E-commerce platforms must prioritize security to maintain trust and protect transactions. OpenCart 4 comes equipped with features to combat fraudulent activities, one of which is the Anti-Fraud IP functionality. This feature allows store administrators to block specific IP addresses suspected of fraudulent behavior, safeguarding the integrity of the store and its customers.
Key Features of Anti-Fraud IP
Custom IP Blocking: Administrators can manually add IP addresses to the blocked list.
Real-Time Monitoring: Detect and flag suspicious activities originating from certain IP addresses.
Integration with Other Anti-Fraud Modules: OpenCart’s Anti-Fraud system integrates seamlessly with extensions that provide additional fraud detection capabilities.
Logs and Reports: View logs of blocked IPs to analyze patterns and improve fraud detection strategies.
Go to Extensions > Extensions > Anti-Fraud> Anti-Fraud IP.
If not installed, install it then click edit it.
Paste the IP in IP input box and Click the Add IP button.
Save the changes.
The blocked IPs will be listed under the Anti-Fraud IP section.
Identify fraudulent IPs
One way to identify fraudulent IP is by analyzing the Recent Activities in the Dashboard activities
We saw the First name and Last name looks suspicious and we click to get the details. Those name looks suspicious and we clicked the IP addresses tab.
We saw two IPs and one IP created multiple accounts:
When we click the 3 in the Total Accounts column, then we got a list of customers with weird name so those are suspicious registration so we blocked that IP.
Other ways to identify fraudulent IPs effectively are by following steps below:
Monitor Website Traffic Logs:
Use tools like Google Analytics, server logs, or third-party monitoring tools to review unusual patterns, such as spikes in requests or repeated access attempts.
Look for Repeated Failed Login Attempts:
Multiple login failures from the same IP might indicate brute-force attempts.
Analyze Suspicious Order Patterns:
Orders with mismatched billing and shipping addresses or unusually large volumes from a single IP.
Check for Scraping Activity:
Bots scraping product data may send multiple rapid requests, which can be traced to specific IPs.
Use Anti-Fraud Tools:
Platforms like FraudLabs Pro or MaxMind can help detect fraudulent IPs by analyzing behavioral patterns.
Engage Real-Time Blacklists (RBL):
Use databases like Spamhaus or Project Honeypot to cross-check IPs against known malicious addresses.
Monitor Failed Payment Attempts:
Repeated payment failures, especially if associated with multiple card details, can signal fraud.
Enable Firewall Alerts:
Security solutions like Cloudflare or Sucuri can provide alerts for unusual IP activity.
Customer Feedback:
If customers report unusual account activity or transactions, investigate the associated IPs.
Geolocation Analysis:
Check if the IP location aligns with the user’s claimed location. Discrepancies might indicate proxy or VPN usage.
Benefits of Blocking Fraudulent IPs
Enhanced Security: Prevent unauthorized access and fraudulent transactions.
Reduced Chargebacks: Mitigate the risk of financial loss due to fraudulent orders.
Improved Customer Trust: Demonstrates a commitment to protecting customer data and transactions.
Better Resource Management: Minimize server load caused by malicious traffic.
Best Practices for Anti-Fraud IP Management
Use Trusted Fraud Detection Services: Integrate third-party fraud detection tools for more comprehensive coverage.
Regularly Monitor Activity Logs: Review logs to identify new threats and patterns.
Whitelist Trusted IPs: Ensure essential partners or services are not accidentally blocked.
Educate Your Team: Train staff to recognize signs of fraudulent behavior.
Conclusion
The Anti-Fraud IP feature in OpenCart 4 provides a robust line of defense against fraudulent activities. By actively monitoring and managing IP addresses, store administrators can enhance security, protect revenue, and foster customer trust. Coupled with other security measures, it is an essential tool for any e-commerce business aiming to stay ahead of fraudsters.
OpenCart 4 provides a robust and flexible design layout system for customizing the appearance and functionality of your online store. One of the standout features is the ability to override design layouts without modifying core files. This functionality ensures that you can implement customizations in a way that’s easy to manage and update. Let’s explore what design layout overrides are, their use cases, and how to implement them effectively.
What Are Design Layout Overrides?
In OpenCart, layouts define how different pages of your store are structured. A layout specifies which modules appear in various positions (e.g., header, footer, sidebar) on a page. Design layout overrides allow you to customize these layouts for specific pages, categories, or products without altering the default settings or core files. This makes your store highly customizable while maintaining compatibility with future updates. This helps on:
Implementing unique promotional layouts
Maintaining upgradability
Creating custom pages
Modifying existing layouts for specific categories or products
Why Use Design Layout Overrides?
1. Custom Page Designs
You can create unique designs for individual pages, such as a custom homepage, promotional landing pages, or special campaign pages.
For example, you might want a “Black Friday Sale” page with its own layout and modules like countdown timers and banners.
2. Category-Specific Layouts
Different categories may require unique layouts based on the type of products they contain.
For example, the “Electronics” category might feature a slideshow of gadgets, while the “Clothing” category displays a carousel of featured apparel.
3. Product-Specific Layouts
Highlight premium or featured products with dedicated layouts.
For instance, a flagship product might have an expanded description, video module, and additional call-to-action buttons.
4. SEO and User Experience Enhancements
Tailored layouts can improve user experience (UX) by presenting content in a way that’s optimized for specific audiences.
This also enhances SEO by ensuring relevant and structured content is displayed for search engines.
How to Implement Design Layout Overrides in OpenCart 4
Follow these steps to apply design layout overrides in OpenCart 4:
Step 1: Access Layouts in Admin Panel
Log in to your OpenCart admin panel.
Navigate to Design > Layouts.
You will see a list of predefined layouts (e.g., Home, Product, Category).
Step 2: Create or Edit a Layout
Click the Add New button to create a new layout or edit an existing one.
Provide a meaningful name for your layout (e.g., “Black Friday Sale”).
Assign the desired route (e.g., black-friday-sale). Routes define where the layout will be applied.
Step 3: Add Modules to Layout Positions
In the layout editor, assign modules (e.g., Banners, Carousels, Latest Products) to specific positions (e.g., Content Top, Content Bottom, Column Left and Column Right).
Configure each module as needed. For example, set banner images or define product categories.
Step 4: Save and Test
Save your changes and navigate to the assigned route in your store.
Verify that the layout displays as expected. Tweak module settings or positions if necessary.
Step 5: Assign Layout to the Category
Edit the category where you want to assign the new layout. Here for an example, we will edit the Camera category and assign the Black Friday Sale layout to override the default category layout.
Then in the frontend the layout is different for the Camera category.
Examples of Layout Overrides
1. Promotional Landing Page
Use Case: A dedicated page for a holiday sale.
Implementation:
Create a new layout.
Assign modules like a countdown timer, featured products, and promotional banners.
Route: promo/holiday-sale.
2. Category-Specific Layout
Use Case: Enhancing the layout of the “Books” category.
Implementation:
Edit the “Category” layout or create a new one.
Assign a carousel module to display bestsellers in “Books.”
Route: category/books.
3. Product-Specific Layout
Use Case: Highlighting a flagship smartphone.
Implementation:
Create a new layout.
Add modules such as a video gallery and a technical specifications block.
Route: product/flagship-smartphone.
Best Practices for Using Design Layout Overrides
Plan Ahead: Sketch your desired layouts and identify which pages need overrides.
Use Descriptive Names: Name your layouts meaningfully to avoid confusion.
Test Thoroughly: Always test your layouts on different devices and browsers.
Keep It Modular: Utilize reusable modules to streamline your design process.
Backup Regularly: Before making major changes, back up your store to avoid data loss.
Conclusion
Design layout overrides in OpenCart 4 provide unparalleled flexibility for customizing your store. By leveraging this feature, you can create unique and engaging shopping experiences tailored to your customers’ needs. With proper planning and implementation, layout overrides can significantly enhance your store’s visual appeal and functionality.

This Opencart tutorial collects the most common errors that we face while developing and provides solutions for errors, try them and hope you could solve the issues
foreach (glob(trim($next, '/') . '/{*,.[!.]*,..?*}', GLOB_BRACE) as $file) {
to following
foreach (glob($next . '/{*,.[!.]*,..?*}', GLOB_MARK|GLOB_BRACE) as $file) {
2. Blank White Pages or 500 Internal Server Error
Blank white pages are a PHP error that for some reason the error messages don’t show because your server is not set up to display the errors.
Go to the admin>> System >> Setting >> Edit store >> Server tab and at the end where you see the Error handling choose Yes to “Display Errors “.
If you still don’t see the error, open php.ini and add code below: display_errors = 1; error_reporting = E_ALL; log_errors = 1;
If you still don’t see the error then open index.php and add code below at the top (line 2): ini_set(‘display_errors’, 1); ini_set(‘log_errors’, 1); error_reporting(E_ALL);
Still seeing the error then, set your “Output Compression Level” to 0 in the System > Settings > Server tab.
If you still see the error, solve the issues but if you did not see the errors then most probably it will be a Server error.
You can see error logs in the file also if you had enabled it.
Above mostly it gets solved and the 500 Internal Server Error can be solved with a similar approach.
2. Undefined Index / Variable
An undefined variable in the source code of a computer program is a variable that is accessed in the code but has not been previously declared by that code. So for that using “isset()” to check if the variable has been set will solve the issue.
Error variant:
Notice: Undefined index: filter in /Applications/XAMPP/xamppfiles/htdocs/opencart303/catalog/controller/product/category.php on lin
Commenting $filter = $this->request->get[‘filter’]; and checking with isset is one way to solve it.
If you get the issue while installing the modules or extensions then you need to check the code or solve the issues or contacting the developer can be also another solution.
3. Undefined Function / Method
Undefined function/method errors are seen when you call those functions or methods that are not defined and not found. IE_ERROR: A fatal error that causes script termination “Fatal error: Call to undefined function” or “Fatal error: Call to undefined method”. It happens if files are not found or the extensions are not compatible with your OpenCart version. Solutions can be below:
Error variant:
Related to OpenCart core files
Fatal error: Uncaught Error: Call to undefined method DB\MySQLi::query()
Fatal error: Uncaught Error: Call to undefined method Cart\Cart::getProducts()
Fatal error: Uncaught Error: Call to undefined method ControllerAccountLogin::validate() in …/catalog/controller/account/login.php:54
Go to the file and check whether the function or methods are defined there.
4. Headers Already Sent
Error variant:
Warning: Cannot modify header information – headers already sent by (output started at /public_html/config.php:31) in /path/public_html/index.php online.
Solution:
Remove spaces at the beginning and end of the file mentioned. Like in the above error check with the config.php
5. Session Issue
The product on the cart is self-cleared.
The product on the cart is cleared after the user logged in.
No items stored at product compares.
OpenCart admin always asking to login and get message “Invalid token session. Please log in again”.
Error variant:
Warning: session_start () [function.session-start]: open (/tmp/…, O_RDWR) failed: No such file or directory (2) in /path/public_html/system /library /session.php on line
Solution:
No such file or directory issue
Open php.ini and add code below:session.save_path = /tmp;
If the solution above does not work, contact your host and ask them how to set session.save_path.
6. Allowed Memory Size Exhausted
This error happens because your memory is not enough to execute the PHP code (uploading large images, deleting a lot of products, sending mass emails, etc). Increasing the memory allocated for PHP will solve the issue.
Error variant:
Fatal error: the Allowed memory size of 1111 bytes exhausted (tried to allocate 1111 bytes) in /path/public_html/system/library/image.php on line
Solution:
Edit php.ini and set memory_limit = 128M;
Or put code below to .htaccess php_value memory_limit 128M
If the above does not works then contacting the hosting providers is only the solution where they can increase the number.
Warning: Use of undefined constant DIR_STORAGE – assumed ‘DIR_STORAGE’ (this will throw an Error in a future version of PHP) in …/config.php on line
Some other errors that you can face are below:
Error: Calls to magic methods are not allowed!
// Stop any magical methods being called
if (substr($this->method, 0, 2) == '__') {
return new \Exception('Error: Calls to magic methods are not allowed!');
}

if (is_file($file)) {
include_once($file);
$proxy = new Proxy();
// Overriding models is a little harder so we have to use
// PHP's magic methods
// In future version we can use runkit
foreach (get_class_methods($class) as $method) {
$proxy->{$method} = $this->callback($this->registry, $route . '/' . $method);
}
$this->registry->set('model_' . str_replace('/', '_', (string)$route), $proxy);
} else {
throw new \Exception('Error: Could not load model ' . $route . '!');
}
}

In this Opencart tutorial, we are showing you how to add HTML in Opencart, similarly how to add google analytics, google tag manager, Adroll, Facebook pixels, MailChimp conversion code, google ads conversion in success page only, and other third-party JavaScript code in the Opencart, likewise our best way to manage the JavaScript code through google tag manager and test and preview in the google tag manager.
How to add HTML in the Opencart?
Opencart has an HTML content module in which you can add the custom HTML in the Opencart and show in any layout you want. Go to admin >> Extensions >> Extensions >> Choose the extension type “Modules”, then look for HTML content and then install it. As HTML content is a multi-instance Opencart module, you can install as many different modules as you want.
Once you install, click the add module button of the HTML content and you will see a form like below:
Click the </> icon then paste the HTML that you have and again click the icon </> and then only the HTML will be saved, else HTML code will not be saved. So be sure to click </> and see WYSIWYG editor and then only click the Save button.
Now, go to admin >> Design >> Layouts and edit where you want to show the module and then select the positions where to show. Here is a video which shows the layouts and position details of Opencart 3
How to add google analytics in the Opencart?
Go to https://google.com/analytics, then log in, choose your accounts and select the “All Web Site Data”, then click in the left menu (1) “Admin”, then to the (2) Tracking Code and then (3) copy the code.
Once you copy the code, go to the Opencart admin >> Extensions >> Extensions >> Choose the extension type “Analytics”. Click the install button.
After install click the edit button and you will see the form like below where you can paste the javascript analytics code.
Similarly, you can add any third-party JavaScript code here like, the google tag manager, Facebook pixels, MailChimp conversion code, etc.
How to add conversion code on the success page of Opencart?
Conversion codes are mostly added on the success page. Here are the steps to add conversions the Opencart way, it may long way but it is Opencart way taking layouts into consideration:
Go to admin >> Extensions >> Extensions >> Choose the extension type “Module” and install the Custom HTML module >> add new >> Enter module name >> Click the </> icon on description >> insert the JavaScript code >> Click the </> icon again >> select Enabled on status >> click Save.
Now, go to admin >> Design >> Layouts
Edit the checkout layout
Change the module name to “Checkout Cart”
In the route field change “checkout/%” to “checkout/cart”
Now, click add a new layout, then enter module name is “Checkout Checkout” and in the route field click “add new” button and add the route as “checkout/checkout” and then click Save.
Similarly, click add a new layout, then enter the module name as “Checkout Success” and in the route field click “add new” button, enter “checkout/success”, then click the add button on the Content Bottom position and select the Conversion code HTML module, then click Save button.
With the above steps, the conversions code is shown only on the success page.
In this way, you can add conversion code on the success page only. We made three different layouts because checkout/% took preferences so we cannot create only checkout/success only. Thus we need to create for all of the routes that checkout contains, thus there are three different layouts.
If you are a developer and using the default theme then you can add the code directly into the code from theme editor. Go to admin >> Design >> Theme Editor >> Choose your store mostly “Default” >> Choose the template “Common” >>then click “success.twig” and add JavaScript code above {{footer}}.
How to add custom JavaScript code and custom CSS code in the Opencart Journal theme?
Go to admin >> Journal >> System >> Settings >> Edit your store >> Then Custom Code >> you can add css and Javascript here.
Our best way to manage third-party JavaScript code is by using Google Tag manager
We use Google Tag Manager to manage third-party JavaScript code and we think this is the best way because all of our external JavaScript will be on Google Tag manager and we can control a lot of things in google tag manager. Go to http://tagmanager.google.com, sign in, and create an account.
Enter the Account Name, select Country, Container Name, and select Web for a website, then click create button. You will get code to add in your website:
Copy the JS code and go to Opencart admin >> Extensions >> Extensions >> Choose extension type “Analytics”, then install the Google Analytics and edit and you can add the Google tag manager code at the “Google Analytics Code”, enabled it and click save. Once these are done, the google tag manager is installed in Opencart.
Now in the Google tag manager admin section, click the Tags, then click New, click Triggering, click “All Pages”, after that click the Tag configuration, choose the custom HTML, where you can add any third party JavaScripts.
Here let’s take an example of MailChimp. Login to the MailChimp, click on the profile, in the dropdown click Connect, then integrations,
Then custom website, enter the website URL, and click “Get Code”.
You will get like below:
Copy that code and paste that code in the google tag manager Custom HTML like below:
Click Save. Then submit.
Enter the version details:
It saved the tag and show details like below:
Now your tag is shown in your Opencart store. Likewise, you can add as many third-party JavaScript codes as you want, similarly, you can add code on different pages with the help of triggers.
In this way, you can add the custom Javascript, custom HTML module, CSS, google analytics, Mailchimp tracking code, google tag manager, etc in the Opencart. Please post your questions or comments or errors so that we can help you. You can follow us at our twitter account @rupaknpl.

In Opencart Order total modules are those which decrease or increase the total price of the total order. Some of the order total which decreases the total price are coupons, store credits, reward points, etc. Some of the order totals which increases the total price are Handling fees, low order fees, taxes, etc. You can see order totals by going to Admin >> Extensions >> Extensions >> Choose the extension type Order Totals, then you will see all the order totals. Some of the default order totals are the following:
Coupon
Store Credit
Handling Fee
Klarna Fee
Low Order Fee
Reward Points
Shipping
Sub-total
Taxes
Total
Gift Voucher
How to install the Order total in Opencart?
Go to Admin >> Extensions >> Extensions >> Choose the extension type “Order Totals” and click the install button that you want to install and Edit it, Enabled it and click Save.
Order totals affect the total price of order so they are placed in the order total so you will find the order total at the shopping cart page and the confirmation page of the order.
Why shipping is not showing in Opencart?
First, check if the shipping order total is enabled or not. If it is not enabled then we need to enabled it. Next is to check for the Geozone setting of Opencart for the products.
How to apply and create the Order total in Opencart?
When we install the Order total modules then it is stored as ‘total’ code in the oc_extension database table. Check the following code how it pulls all the enabled Order total and applied it to the order total costs.
$results = $this->model_setting_extension->getExtensions('total');
foreach ($results as $key => $value) {
$sort_order[$key] = $this->config->get('total_' . $value['code'] . '_sort_order');
}
array_multisort($sort_order, SORT_ASC, $results);
foreach ($results as $result) {
if ($this->config->get('total_' . $result['code'] . '_status')) {
$this->load->model('extension/total/' . $result['code']);
// We have to put the totals in an array so that they pass by reference.
$this->{'model_extension_total_' . $result['code']}->getTotal($total_data);
}
}
We hope this post may help you understand the Order total of Opencart 3. Let us know if you have any questions or suggestions, please subscribe to our YouTube Channel for Opencart video tutorials. You can also find us on Twitter and Facebook. Enjoy!
With the launch of Opencart 4 and lots of changes, today we are showing how we can install the Opencart 4 theme and how to create the Opencart 4 theme admin section. How to install is the Opencart user manual, and we will go through all the code for the developer guide. For demo purposes we are showing you the admin section in this tutorial and in the next upcoming Opencart 4 tutorial, we will go through Opencart frontend settings and codes.
Once you download the above, you will get a zip file named webocreation4.ocmod.zip, then go to Opencart admin >> Extensions >> Installer >> Click the blue upload button. Once the upload is completed, it will list in the Installed Extensions, when you can click the install green button.
Now, go to Extensions >> Extensions >> Choose the extension type >> Themes
Click the green install button on the new theme, and you can uninstall the old one. Then, click the blue edit button and change the status to enable, and click Save.
With these, your new Opencart 4 theme is active.
How to uninstall the Opencart 4 theme?
Login into Opencart admin, then Extensions >> Installer >> Find the theme and click Uninstall. If you totally want to remove it then you can delete it.
File and folders structure of the Opencart 4 theme
Now all theme files and folders also reside in the extension folder. The theme folder should be inside the theme folder. Here is one example of how the admin files and folders reside, overall our main theme folder is named “webocreation4” and all the files are named as standard.***. You can name them as you like.
Admin Language of custom Opencart 4 theme
Let’s start by creating the language file for the Opencart 4 theme. Create files and fodlers like extension >> webocreation4 >> admin >> language >> en-gb >> theme >> theme_standard.php. Here is one simple example of texts added for our custom theme.
<?php
// Heading
$_['heading_title'] = 'Webocreation Theme';
// Text
$_['text_extension'] = 'Extensions';
$_['text_success'] = 'Success: You have modified the Webocreation theme!';
$_['text_edit'] = 'Edit Webocreation Theme';
// Entry
$_['entry_status'] = 'Status';
// Error
$_['error_permission'] = 'Warning: You do not have permission to modify the Webocreation theme!';
Admin View of custom Opencart 4 theme
Create a new file at extension >> webocreation4 >> admin >> view >> template >> theme and create theme_standard.twig. Paste following code. Most of the code are similar to other modules.
“Check the Select field name, which is name=”theme_standard_status” the name of all settings for theme should start with theme_ and then with the file name, as our file name is standard.php so each field name should start with theme_standard_
Only we need to make sure that the field names start with theme_standard_, others are similar to other module codes.
Admin Controller of custom Opencart 4 theme
Now, let’s create a controller file and folders like extension >> webocreation4 >> admin >> controller >> theme >> theme_standard.php. Now you can add following code, we are describing some important code below:
Now Opencart 4 starts using namespace a powerful concept that provides a way to organize code into groups that allow you to create reusable components that can be reused across multiple projects. So, each Opencart modules, theme, and all extensions now start with a namespace. As we are creating a theme so at the end it is Theme, if you are creating a module, it will be Module, if you are creating an analytics extension then it will be Analytics.
Now, in the second line, we create the class with the name same as the file, as our file name is standard.php, so we name the class as Standard and inherits the main Opencart controller.
class ThemeStandard extends \Opencart\System\Engine\Controller
Now, we create an index method and add the return type
public function index(): void
In the index method, all other codes are similar to other modules and extensions, one line of code that you need to look at is below where you add the theme_standard as the first parameter. This first parameter and each field name of the form should start with the same so here in our example is theme_standard
Another code to look into is below, right now we have one field so it is like below, you need to do similar for each field that you will add. $setting_info holds all the setting that is given by the above getSetting method.
The first parameter of editSetting method should be theme_standard.
Above is the main code that we need to check and change, other similar to all other Opencart 4 modules or extensions or themes.
public function install(): void
{
if ($this->user->hasPermission('modify', 'extension/webocreation4/theme/standard')) {
$this->load->model('setting/startup');
$this->model_setting_startup->addStartup('theme_standard', 'catalog/extension/webocreation4/startup/standard', 1, 2);
}
}
The above code will add the Startup like below which we will be using in the catalog code, which we will show in the next upcoming post.
Likewise, we add the uninstall code like below so that all rows are removed from the database
public function uninstall(): void
{
if ($this->user->hasPermission('modify', 'extension/webocreation4/theme/standard')) {
$this->load->model('setting/startup');
$this->model_setting_startup->deleteStartupByCode('theme_standard');
}
}
In this way, you can install and create a new custom Opencart 4 theme and create the form in the admin section where you can add the setting for the custom theme. Hope you liked this article, please subscribe to our YouTube Channel for Opencart video tutorials. You can also find us on Webocreation Twitter and Webocreation Facebook. Please let us know if you have any questions or concerns. In our next upcoming tutorial, we will go through how to show in the frontend, as now everything is events based so there will be a lot of changes for the new frontend changes of the Opencart 4 custom theme. Please let us know if you have any questions or concerns.

Opencart 4 and 3 has lots of reportings, it is in the Reports section and some are available in the admin dashboard as well. But still, there are some functionalities that are missing like exporting on CSV or excels, reporting on charts and sometimes the best report of what visitors are doing on your website is tricky, however, to get the best reporting we would recommend you use Google analytics enhanced reporting as well so that you can analyze what visitors and customers are doing in your website and get best decisions. In this way, you can see reporting in Opencart 4 and 3. Please don’t forget to post your questions or comments. Additionally, this will allow us to add extra topics.

In this Opencart tips and tricks, we are showing you 25 Opencart security tactics to make Opencart’s website secure by providing a cheat sheet for Opencart eCommerce users, so that the customers can buy products confidently which may increase your conversion rates. Here are the 25 lists of things that you can do to make the Opencart website secure:
Use good and secure hosting
Research and buy good, reliable, and secure hosting.
Check if the install/ folder is still there
Once Opencart is installed, you need to remove/delete the install/ folder. Renaming the folder will also have a security hole. Thus, always delete the install/ folder.
Proper Security settings in the admin
Login to the admin section >> System >> Settings >> Edit required store >> then in the Server tab, select the use SSL to Yes
Use SSL: To use SSL check with your host if an SSL certificate is installed and add the SSL URL to the catalog and admin config files.
Allow Forgotten Password: Allow forgotten passwords to be used for the admin. This will be disabled automatically if the system detects a hack attempt.
Use Shared Sessions: Try to share the session cookie between stores so the cart can be passed between different domains.
Encryption Key: Please provide a secret key that will be used to encrypt private information when processing orders.
Use HTTPS/SSL Certificate
Selecting SSL to Yes on the above setting will not give you an HTTPS URL, your server also need to have SSL installed. Nowadays most servers provide free encrypt SSL certificates which can be setups with just some clicks, or you can use more secure SSL certificates.
One thing you need to take care of is all of your URL links need to start with HTTPS:// instead of HTTP:// else it will not be fully secured. If you are using external URLs, make sure they start with HTTPS://. With proper SSL installation, your URL will look like the below when you clicked on the SSL icon:
Protect your storage/ folder and other files like the config.php file and admin/config.php
Keep storage/ folder outside of the public_html folder. In the image below, my storage folder is v3storage. Similarly, check your file permission and keep it below 0644.
Use the latest PHP version
See the chart the PHP V5.6 is already at the end of its life which means there will be no update of security, and they are exposed to unpatched security vulnerabilities. So for security always use the latest version of PHP.
https://www.php.net/supported-versions.php
Watch this session, on how the creator of PHP describes the performance in PHP 7. Performance always good impact.
Use Anti-fraud extension
Opencart by default provides some Anti-fraud extensions, they help store owner to secure their online e-commerce website from malicious fraudsters and make it more secure. Login to admin >> Extensions >> Extensions >> Choose the extension type as Anti-Fraud >> then you will see lists of modules that you can use. You can use some of them for free like 500 queries/month.
Error handling setting
Enable error logging into the error.log file and it will insert into the database. It is a better idea not to display errors. If you display errors then it will show all full paths of files and it may help hackers. While you perform your debugging errors you can enable it but for security reasons keep it checked as No. You can set the error handling at admin >> System >> Settings >> edit Your Store >> Server tab and you will see the error handling section at the end.
Monitor your admin error logs
Analyzing error logs also gives what issues are happening and fixing them is important. Similarly, check logs at admin >> Extensions >> Modifications >> Log tab. Fixing errors makes the site more secure.
Block bad bots
Opencart provides settings for Robots. You can get it at admin >> System >> Settings >> Edit Your Store >> Server tab and you can see the Robots field. A list of web crawler user agents that shared sessions will not be used with. Use separate lines for each user agent.
Be sure there are no PHP and JS. In this way, you can secure your file upload buttons.
Review All Users, User group and Grant the Minimum Permissions Necessary
Go to admin >> System >> Users and see all users and verify what user group is assigned. Then check all User groups and see what access permission and modification permissions are given. Try to grant the minimum permissions as necessary. In Opencart you can make as many User groups as you want.
Use a strong username and password
Set a strong password. Better not to use admin as a username.
Opencart V3 has Max Login Attempts
Maximum login attempts are allowed before the account is locked for 1 hour. Customer and affiliate accounts can be unlocked on the customer or affiliate admin pages.
It is available only on Opencart v3 but you can implement this by following the tutorials at https://forum.opencart.com/viewtopic.php?t=218405#p790296
Similarly, check your API access as well. Go to admin >> System >> Users >> API and review all your API usernames and set proper API usernames, API keys, and IP addresses.
Always use the latest Opencart version, theme, modules, and extensions
It is better to use the latest Opencart version, theme, modules, and extensions. You may get problems getting the upgraded version of your custom modules and extensions but if you don’t update it then you risk the security.
Remove unused modules or extensions
Login to admin >> Extensions >> Installer >> you can see a list of modules that are installed. Remove unused modules or extensions. Similarly verify if old files and folders are remaining, especially for custom modules and themes.
Don’t use nulled Opencart theme or modules or extensions
Choose trustworthy plugins and theme providers, it can cost you some but it will protect you a lot.
Monitor your server logs as well
If you are using CPanel hosting then you can check the Resources Usage at Login to Cpanel >> Metrics >> Resources Usage >> Snapshots. You can check that resource limits are being reached, resulting in slow performance or errors. Often resource issues are due to scripting/plugins on your site, development work such as making changes, or an increased amount of traffic. You and your web developer can review the resource usage of your account and take steps to reduce the load. Some scripts which are running long by some IP address means there is some fishy going on, so make sure to keep on checking it and see if you can improve your code and scripts.
If the programmer is tricky then in Opencart it is easy to add the JS script which may easily cause Cross-Site Scripting. Cross-Site Scripting (XSS) is when a malicious script is injected into a trusted website or application. The attacker uses this to send malicious code, typically browser-side scripts, to the end-user without them knowing it. The purpose is usually to grab cookies or session data or perhaps even rewrite HTML on a page. Go to admin>> Extensions >> Extensions >> Choose the Extensions Type as “Analytics” and see in the Google Analytics code field, if only required JS codes are added. If you see suspicious JS code then better to remove it.
Database Security and SQL Injections
Always use a strong database username and strong password. You can check this at config.php and admin/config.php, if you don’t have then you need to change to a strong password and username.
Similarly, if you are using custom modules and there are database queries then you need to verify whether the queries are written properly, whether all the fields are escaped properly or not and so.
One example of how they can inject the extra queries if you don’t escape the fields is below:
See that bold section in the above queries, another query is concatenated and SQL injected is done.
Denial of Service
This is the most dangerous vulnerability, Denial of Service (DoS) exploits errors and bugs in the code to overwhelm the memory of website operating systems. Hackers have compromised millions of websites and raked in millions of dollars by exploiting outdated and buggy versions of Opencart software with DoS attacks. The hackers keep on running the code and your server CPU usage will be 100%, your server’s Physical Memory Usage is full and the website will not be available for real users or customers.
One of the best recommendations is to use a reputable 3rd party security service like Cloudflare or Sucuri and be sure to use the code and scripts properly.
Back up
Be sure to make as much backup as possible.
Use Google Captcha or Basic Captcha
Using Google Captcha or basic captcha on the form also helps you remove spam and get emails that contain vulnerable links.
These are some of the securities cheat sheets for Opencart. Please let us know if you are using any other tactics to make the Opencart website secure.

Opencart multiple websites. It can handle multiple stores with one Opencart installation. Creating a Multi-Store Opencart allows for multi-store management using only one installation. If you have installed Opencart into at least one store, you can add multiple stores to your admin panel without having to repeat the installation process. To add a new store you must first create a subdomain in your cPanel, then add the store in the Settings section of the admin panel.
OpenCart 4 allows you to manage multiple online stores from a single admin interface. This multi-site capability is particularly useful for businesses that operate in different regions, sell various product lines, or want to create separate storefronts for different customer segments. Setting up multiple sites in OpenCart is straightforward and provides a centralized way to control and monitor all your stores.
Benefits of a Multisite Setup
Centralized Management: Manage multiple stores from a single admin dashboard. One admin management with one log in for products, categories, customers, orders, design, etc
Shared Resources: Use the same product catalog, customer database, and settings across multiple stores. You can configure each product to show on which store and can set different prices for the same product
Customized Storefronts: Tailor the appearance and functionality of each store to target specific audiences. Although having one admin management, you can have different layouts and different themes for different stores
Cost-Effective: Save on infrastructure and maintenance costs by running multiple stores on the same installation.
Customer easiness: Customers can have a single sign-on for different stores that are managed on multiple.
Prerequisites
Before setting up multiple stores, ensure you have the following:
A working installation of OpenCart 4 on the server (In our example we are using demo.webocreation.com)
Administrative access to the OpenCart admin panel.
Domain names or subdomains for each store, both the server and
DNS Domain name server settings
You use the addon domain in cpanel to add the 2nd domain to your hosting account. Then change the document root in that 2nd domain to be the same as your first store – the folder opencart is installed in. Add the store to opencart settings and done.
Point their A records to the IP of your server.
Associate them with that hosting account which can be done in cPanel via “Aliases” which used to be called “Parked Domains” if I remember correctly.
Step-by-Step Guide to Setting Up Multisite in OpenCart 4
Step 1: Configure Your Domain/Subdomain
First, set up your additional domains or subdomains. This process will vary depending on your hosting provider but generally involves the following steps:
DNS management: Access to domain registrar admin section so you can point domain A records to the server. In this example, we are using Cloudflare DNS so we added the A records like below, as in this example we are using sub-domain demo2.webocreation.com and demo3.webocreation.com, so pointed the A record to the IP address. Fig: 2
For main domains like dpsignadvertising.com, you need to delegate the same name server that you are using for the opencart installed server, here is https://demo.webocreation.com, so for dpsignadvertising.com, we add the same ns1 and ns2 as demo.webocreation.com
Fig: 12.3
Subdomains: Create subdomains (e.g., store1.yourdomain.com, store2.yourdomain.com) and point them to the OpenCart installation directory.
Fig: 12.4
Then click “Create a New Domain” enter the domain URL and submit, here we entered demo3.webocreation.com
Similarly, you can enter as many domains as needed.
Domains: Same as sub-domains, point each domain to the root directory of your OpenCart installation. We are using the cPanel so we find the domain section, for us here is an example, click in the Domains and enter the domains.
2: Add New Stores in OpenCart Admin
Log in to Admin Panel: Log in to your OpenCart admin dashboard.
Navigate to Store Settings: Go to System -> Settings.
Add New Store:
Click the “+” button to add a new store.
Store Name: Enter the name of the new store.
Store URL: Enter the URL of the new store, including the trailing slashLog in., https://dpsignadvertising.com/).
If you forget the trailing slash multi-store will not work
3: Configure Store Settings
General Settings: Configure general settings such as store name, owner, address, email, and phone number. You can select different themes, logos, and layouts for each store
Local Settings: Set local settings like country, region, language, and currency for the new store.
Option Settings: Set all settings like products, legal, etc for the new store.
Image Settings: Enter the image sizes
4: Customize Your Store
Themes: Go to Design -> Themes and select a theme for your new store. You can choose to use the same theme as your main store or a different one.
Layouts: Customize the layouts for your new store by navigating to Design -> Layouts. Adjust the positions and modules according to your requirements.
Banners and Sliders: Set up banners and sliders specific to the new store under Design -> Banners.
5: Assign Products and Categories
Products: Navigate to Catalog -> Products and edit each product to assign it to the new store. Use the “Stores” tab to select the stores where the product should be visible.
Categories: Go to Catalog -> Categories and assign categories to the new store using the “Stores” tab.
6: Test Your Store
Access the Store URL: Open a web browser and navigate to the URL of your new store.
Verify Functionality: Ensure that all links, images, and functionalities are working correctly.
Place a Test Order: Complete a test purchase to verify that the checkout process is functioning correctly.
Setting up a multisite environment in OpenCart 4 is an efficient way to manage multiple online stores from a single admin interface. By following the steps outlined above, you can configure and customize each store to meet the needs of different markets or customer segments. This powerful feature of OpenCart helps streamline operations, reduce costs, and expand your business reach effectively.
This tutorial covers how to change the timezone in OpenCart as well as change time of the database.
Go to system/startup.php and find following lines of code:
if (!ini_get('date.timezone')) {
date_default_timezone_set('UTC');
}
Replace with following lines of code by changing to your timezone
date_default_timezone_set('Australia/Sydney');
Synchronize PHP and Database Timezone
The query we use to set database timezone if you are super admin is below:
SET time_zone='offset';
But everyone has no super admin access so need to change in the code level. For that go to system/library/db/mysqli.php if you are using MySQLi and add code below after $this->connection->query(“SET SQL_MODE = ””);
$dt = new \DateTime();
$this->connection->query("SET time_zone='" . $dt->format('P') . "';");
With these changes your timezone in Opencart are changed.

In this Opencart tutorial, we go through OpenCart Events. Opencart events are hooks that developers can attach custom code to, allowing them to execute specific actions at different points in the application’s lifecycle. Events can be triggered by various actions within the OpenCart system, such as user authentication, order creation, product editing, email sending, and more.
Event Types
Pre-Events:
Triggered before a specific action occurs. For example, a pre-event can be triggered before an order is saved, allowing developers to perform custom actions like validating order data.
Post-Events:
Triggered after a specific action occurs. For example, a post-event can be triggered after a product is edited, allowing developers to perform custom actions like updating related data.
Using OpenCart Events:
To use OpenCart events, developers need to create an event listener, which is a function or method that responds to a specific event. An event completes the tasks that a controller, a model, a theme override, a language, and a config need to be achieved in the back-end of the store. Upon startup, the Engine automatically registers triggers, actions, and sorts orders in both the admin/controller/startup/event.php and catalog/controller/startup/event.php files.
Event listeners are registered using the addEvent method from the Event class. The method takes three parameters: the event name, the class/method to be executed, and the priority of the listener.
Example Code:
// In your custom extension, add this code to the controller
$this->event->addEvent('catalog/controller/product/product/after', 'extension/event/custom_event/afterProductView');
// Define the event listener in your custom event class
class ControllerExtensionEventCustomEvent extends Controller {
public function afterProductView(&$route, &$data, &$output) {
// Custom code to execute after a product view
// Example: modify the product data before it's rendered
$data['custom_text'] = 'This is a custom message after product view.';
}
}
Registering Events:
Events can be registered in an extension’s install method or directly in the controller if needed.
It’s important to unregister events in the extension’s uninstall method to avoid any unwanted behavior after removing the extension.
Using Events for Customization:
Developers can use OpenCart events to customize and extend the platform in various ways, such as:
Adding custom logic to product pages, checkout processes, or other areas of the platform.
Modifying data before it’s displayed to the user.
Integrating with third-party services or APIs.
For developers, add event code, description, trigger, and action in the database. The action is the method that does what you want. The trigger is the path that you want for the existing Opencart controller and methods.
You can see all the events at >> Admin >> Extensions >> Events
List of Events
Catalog and administer events. Here are the lists of Catalog events for different functionalities.
Language events
OpenCart’s language events system is an important part of managing and customizing language-related aspects of the platform. Language events allow developers to add, modify, or manipulate language files and translations within the OpenCart application. This is crucial for providing multilingual support and customizing the text displayed to users.
view/*/before
Dump all the language vars into the template.
controller/*/before
Before the controller loads stores all current loaded language data
controller/*/after
After the controller loads and stores all current loaded language data
Activity events
OpenCart’s activity events system allows developers to monitor and respond to user activities and other important events within the platform. These events are useful for tracking user actions, generating logs, and performing custom operations based on specific activities. This system enhances the ability to understand user behavior, provides better support, and maintains the platform effectively.
Here’s an overview of OpenCart activity events and how you can use them:
Understanding Activity Events:
Activity events in OpenCart track significant actions performed by users, such as login, logout, product views, purchases, and more.
These events enable developers to create custom responses and logs based on specific user activities.
Common Activity Events:
customer_login: Triggered when a customer logs in. This event is useful for monitoring login activity or taking specific actions upon login.
customer_logout: Triggered when a customer logs out. You can use this event to perform cleanup operations or logging.
product_viewed: Triggered when a product is viewed. Useful for tracking product popularity or taking custom actions based on product views.
order_added: Triggered when a new order is added. This event can be used to log order information or trigger post-order processes.
customer_register: Triggered when a customer registers a new account. Useful for sending welcome emails or performing other onboarding activities.
Creating Activity Event Listeners:
To use activity events, create event listeners that respond to specific events of interest.
Register event listeners in your extension’s controller using the addEvent method from the Event class.
// Registering an activity event listener in your controller
$this->event->addEvent('customer_login', 'extension/event/activity/onCustomerLogin');
// Define the event listener method in your custom event class
class ControllerExtensionEventActivity extends Controller {
public function onCustomerLogin(&$route, &$args, &$output) {
// Custom code to execute when a customer logs in
// For example, log the customer login event
$this->log->write('Customer logged in: ' . $args['customer_id']);
}
}
OpenCart’s theme events system allows developers to customize and extend the behavior of themes within the platform. By using Theme events, you can modify how themes render content, alter page elements, and integrate custom logic to achieve a unique look and feel for your store.
Here’s an overview of OpenCart theme events and how you can utilize them:
Understanding Theme Events:
Theme Events are hooks that allow you to customize the rendering of pages and elements in your OpenCart theme.
These events are triggered during different stages of the rendering process and provide opportunities to manipulate the data or layout before it’s displayed to users.
Common Theme Events:
view/*/before: Triggered before rendering a view file in a specific directory, such as catalog/view/theme/[theme_name].
view/*/after: Triggered after rendering a view file in a specific directory.
template/*/before: Triggered before rendering a template file in a specific directory, such as catalog/view/theme/[theme_name]/template.
template/*/after: Triggered after rendering a template file in a specific directory.
Creating Theme Event Listeners:
To use the theme events, you need to create event listeners that respond to the specific events you want to customize.
Register event listeners in your extension’s controller using the addEvent method from the Event class.
// Registering a theme event listener in your controller
$this->event->addEvent('view/common/header/before', 'extension/event/theme/customizeHeader');
// Define the event listener method in your custom event class
class ControllerExtensionEventThemeCustomizeHeader extends Controller {
public function customizeHeader(&$route, &$data, &$output) {
// Custom code to modify the header before rendering
$data['custom_message'] = 'Welcome to our store!';
}
}
Here are lists of Opencart theme events:
view/*/before
view/*/after
template/*/before
template/*/after
Here is the main code for the catalog that controls the theme events: upload/catalog/controller/event/theme.php
class Theme extends \Opencart\System\Engine\Controller {
/**
* Index
*
* @param string $route
* @param array<int, mixed> $args
* @param string $code
*
* @return void
*/
public function index(string &$route, array &$args, string &$code): void {
// If there is a theme override we should get it
$this->load->model('design/theme');
$theme_info = $this->model_design_theme->getTheme($route, $this->config->get('config_theme'));
if ($theme_info) {
$code = html_entity_decode($theme_info['code'], ENT_QUOTES, 'UTF-8');
}
}
}
Admin Currency Events
model/setting/setting/editSetting
model/localisation/currency/addCurrency
model/localisation/currency/editCurrency
Admin Statistics Events
admin/model/catalog/review/addReview/after
admin/model/catalog/review/deleteReview/after
admin/model/sale/returns/addReturn/after
admin/model/sale/returns/deleteReturn/after
Translation Event
OpenCart’s translation events system allows developers to customize and extend the language and translation aspects of the platform. By using translation events, you can modify or extend the existing translations, add new language strings, and customize language files to achieve a more personalized or localized experience for your store. Here is the main code that you can find at upload/catalog/controller/event/translation.php and upload/admin/controller/design/translation.php
By default, in the system/config/catalog.php file, the debug key and value are commented out at the bottom of the file because they should only be active for debugging purposes. Remove the comment from the code like below:
After enabling debugging, you can test the code within the catalog/controller/event/debug.php file. You see the after and before methods. Here is an example of an after-method test to find all the routes used on the page.
It is essential to undo the changes of the debugging by commenting out the debug line in the system/config/catalog.php file after testing.
Challenges
Performance Impact: Every event adds a layer of processing, which can slightly impact page load times, especially with numerous event handlers. Monitor performance and prioritize essential events to avoid noticeable slowdowns.
Debugging Complexity: Debugging problems within event handlers can be more challenging than traditional code because they may be triggered from different locations. Employ proper logging and testing practices to identify and resolve issues effectively.
Security Risks: Improper event handler implementation might introduce security vulnerabilities. Always validate and sanitize user input within event handlers to prevent potential security risks.
Maintenance burden: As your store and codebase grow, managing numerous event handlers can become complex. Organize your events and handlers logically, document their purpose, and update them regularly to maintain code clarity and avoid conflicts.
Version compatibility: While events strive for backward compatibility, updates to core files or other extensions might break event handlers. Thoroughly test your events after updates to ensure continued functionality.
Best Practices while using Opencart Events:
Use events judiciously: Don’t overuse events for simple tasks that can be handled efficiently within core files. Reserve events for extending functionality beyond core capabilities.
Write clean and efficient code: Optimize your event handlers for performance and avoid unnecessary processing.
Test thoroughly: Test your event handlers under various scenarios, including edge cases and potential conflicts with other extensions.
Document your work: Document the purpose and logic of your event handlers to facilitate future maintenance and collaboration.
Stay updated: Monitor changes in OpenCart and event-related functionality to adapt your code when necessary.
In Opencart 3 we can manage the order statuses. For that go to admin >> System >> Localization >> Order Statuses then click “Add New” and you can enter the Order Status Name. In this section, you can create order statuses that you can use on Payment gateways and manage sales orders. The image below shows default order statuses provided in the Opencart 3:
By default, Opencart provided all the possible order statuses but if you want to add a new order status for your requirement. Then click then click “Add New” blue button in the top right and you will get the form like below:
Enter the order status name and click save and your order status is saved so that you can see it in multiple places like Sales orders, payment gateway settings and many more.
Order status global setting
There are some order status settings at admin >> System >> Settings >> edit the store >> click Options tab and go to the checkout section where you can find following order status settings:
Order Status: Set the default order status when an order is processed.
Processing Order Status: Set the order status the customer’s order must reach before the order starts stock subtraction and coupon, voucher and rewards redemption.
Complete Order Status: Set the order status the customer’s order must reach before they are allowed to access their downloadable products and gift vouchers.
Fraud Order Status: Set the order status when a customer is suspected of trying to alter the order payment details or use a coupon, gift voucher or reward points that have already been used.
Order statuses at Payment gateways
With the above default settings for order statuses, each payment gateway has its own order statuses settings. Like for example, the PayPal payments standard module supports all the order status like in the below example. If an order is canceled then the logged order status will be Canceled as per the setting below. So don’t forget to set up the order status for the payment gateway that you are using. For that go to admin >> Extensions >> Extensions >> Choose the payments as the extension type, which will list out all the payment gateways that are available and edit the one you are using and check the order status.
For Cash on Delivery, the order status is only pending as per the setting below as it does not have all other settings support like for the PayPal. So when someone ordered with Cash on Delivery then all order goes to pending then you can change it on Order History.
Customer Order status in Order History
In the image below the order status is shown in the Order history section. To see it go to admin >> Sales >> Orders >> View one of the order. Then in the Order History section, you can see the drop-down of Oder status which you can notify the customer if needed with the order status. If you don’t notify then it will not show in the order history of the customer at the frontend section. Like this the order status is used, so you can add new order status as per your need.
You can see the order statuses mostly in payment gateways, sales orders, and Customer Orders Report. You can get reports as per the filtering of the order status.
Customers can see the order status when they check their Order history and view their order. Their order statuses are shown in the Order history section:
In this way, you can manage the Order statuses in Opencart. Please don’t forget to post your questions or comments so that we can add extra topics. You can follow us at our twitter account @rupaknpl, subscribe to our YouTube channel for opencart tutorials, and click to see all Opencart user manual.
In Opencart 3 we can manage the stock statuses. For that go to admin >> System >> Localization >> Stock Statuses then you can enter the Stock Status Name. In this section, you can create Out of Stock statuses to be displayed on the product page when a product is out of stock. The image below shows default stock statuses:
Opencart has multiple stock settings at admin >> System >> Settings >> Edit the store >> and go to Option tab >> Stock section, you will see multiple settings for Stock.
Display Stock: Display stock quantity on the product page.
Show Out Of Stock Warning: Display out of stock message on the shopping cart page if a product is out of stock but stock checkout is yes. (Warning always shows if stock checkout is no)
Stock Checkout: If selected yes it allows customers to still check out if the products they are ordering are not in stock.
If you select the Display Stock to Yes then you can select which Stock Status name to show on the product page. Go to admin >> Catalog >> Products >> Edit/Add the product >> go to the Data tab, then go to the Out Of Stock Status field then you can choose which Stock status name to show in the frontend on the product page.
As in the below image, it will show the Out of Stock Status in the frontend.
In this way, you can manage the Stock statuses in Opencart. Please don’t forget to post your questions or comments so that we can add extra topics. You can follow us at our twitter account @rupaknpl, subscribe to our YouTube channel for Opencart tutorials, and click to see all Opencart user manual.
