What to Look for in an OpenCart Developer for Your Customization and How to Validate Their Work

When you hire an experienced OpenCart developer, you ensure that your eCommerce store will work appropriately and meet your demands. OpenCart is powerful software; however, customization of the software requires a special set of skills. Here are the aspects you will require to look into while hiring an OpenCart developer and how you can check his/her work.

Key Skills An OpenCart Developer Should Have

Following are the Opencart developer traits:

Experience In OpenCart Development

A qualified developer will have hands-on experience in OpenCart, specifically:
In-depth understanding of the core structure of OpenCart.
Knowledge about OpenCart modules and extensions.
Familiarity with the admin panel and customization options of OpenCart.

Strong Knowledge Of PHP

Since OpenCart is basically designed in PHP, the developer will be required to have good knowledge of:
Writing extremely efficient and clean PHP code.
Application of the MVC (Model-View-Controller) architecture in OpenCart.
Debugging PHP errors and optimizing performance.

Expertise In HTML, CSS, And Bootstrap Framework

To be in front-end customization, the developer will have:
Strong knowledge of HTML and CSS to manipulate layouts and styles.
Experience with the bootstrap framework for developing responsive designs.
Ability to create mobile-friendly and user-friendly interfaces.

OCMOD And VqMod Customization

A good OpenCart developer would have a good grasp in:
Using OCMOD (OpenCart Modification System) for smooth, efficient code modifications.
The knowledge of VqMod (Virtual Quick Mod): to override core files without making direct changes.

Understanding Of Server-Side Issues

Most OpenCart stores are hosted on servers using cPanel with an added advantage of Apache. The developer should know about:
How to configure the .htaccess for SEO friendly URL and security upgrades.
Responsible for managing Apache configuration and troubleshooting server-related issues.
How to handle MySQL database operations to optimize speed.

How to Validate OpenCart Developer’s Work

Once you hire a developer, you should assure quality in their work. Some ways of validating this work include:

Code Quality and Best Practices

You want to assure that the code is in compliance with the OpenCart development guidelines.
See that OCMOD/VqMod are being leveraged rather than modifying core files directly.
Check that the code is well-commented and structured.

Performance and Security Checks

Test page load speed to ensure no unnecessary slows.
Check the security measures, like protection against SQL injection and CSRF.
Verify .htaccess security and SEO configuration.

Functionality Testing

General testing should confirm custom features function properly.
Check compatibility with existing extensions and themes.
Cross-browser testing for responsiveness using a wide range of devices.

SEO and URL Structure

Make sure that SEO-friendly URLs have been established properly.
Check for meta-data, alt tags, and structured data setting up.
Test OpenCart built-in SEO features for completeness.

Backup and Documentation

Check for post-change backup from the developer.
Request for documentation of customizations worthy of future reference.
Assure rollback plans for the issue at hand.

Conclusion

Finding the right OpenCart developer for your customizations will require assessment in technical capability, knowledge of OpenCart architecture, and addressing server-side tasks. Testing, checking performance, and documentation around the work done becomes essential in ensuring a smooth and efficient eCommerce experience. Keep focus on these factors and maintain a secure, scalable, and high-performing OpenCart store to suit your business needs.

How to Customize the 404 Not Found Page in OpenCart

A well-designed 404 Not Found page is crucial for improving user experience and retaining customers who land on unavailable pages. OpenCart allows you to customize this page to align with your branding and provide useful navigation options.

Mostly, the 404 page looks like below in Opencart:

Steps to Customize the 404 Page in OpenCart

We used to need the custom module or extensions for these kinds of functionalities, but with the introduction of Language Editor in Opencart, it is easier. If you are looking to just edit the “The page you requested cannot be found!”, then you can easily do it by the language editor of Opencart. Go to the admin section >> Design >> Language Editor and click the Add button

Enter the following details:

Now the 404 will look like below:

Example 404 page:

Here is one design and code example to show the different titles for Category not found, product not found, and other not found.

Design as per category, product, and other page:

Add the following code to the language editor:


<div class="error-container">  
  <!-- Dynamic Error Title -->
  <h1 class="error-title" id="error-title">Oops! 404 Page Not Found</h1>

  <!-- Dynamic Error Message -->
  <p class="error-message" id="error-message">
    The page you are looking for doesn’t exist or has been moved. Try searching for what you need.
  </p>

  <!-- Search Bar -->
  <div class="p-5">
    <form id="searchbottom" method="get" action="index.php" class="input-group mb-3">
      <input type="hidden" name="language" value="en-gb"> 
      <input type="hidden" name="route" value="product/search">
      <input type="text" name="search" value="" placeholder="Search for products" class="form-control form-control-lg">  
      <button type="submit" class="btn btn-light btn-lg"><i class="fa-solid fa-magnifying-glass"></i></button>
    </form>
  </div>
  <!-- Call to Action -->
  <a href="/" class="btn btn-primary-home btn-lg">Go to Homepage</a>
</div>

<style>
  .error-container {
      border-radius: 10px;
      padding: 3rem;
      margin: auto;
      text-align: center;
      background: linear-gradient(135deg, #ff6f61, #d6a4a4);
      color: #fff;
      margin: 0;
  }
  .error-title {
      font-size: 3rem;
      font-weight: bold;
      margin-bottom: 1rem;
      color: #fff;
  }
  .error-message {
      font-size: 1.5rem;
      margin-bottom: 2rem;
      line-height: 2rem;
  }
  .btn-primary-home {
      background-color: #d9534f;
      border-color: #d9534f;
      color: #fff;
  }
</style>
<script>
  // Function to get the value of a specific query parameter from the URL
  function getQueryParam(param) {
    const urlParams = new URLSearchParams(window.location.search);
    return urlParams.get(param);
  }
  // Get the 'route' parameter from the URL
  const routeParam = getQueryParam("route");
  const errorTitle = document.getElementById("error-title");
  const errorMessage = document.getElementById("error-message");
  // Determine the error type based on the route parameter
  if (routeParam === "product/product") {
    errorTitle.textContent = "Product Not Found";
    errorMessage.textContent =
      "We couldn’t find the product you’re looking for. Try searching below.";
  } else if (routeParam === "product/category") {
    errorTitle.textContent = "Category Not Found";
    errorMessage.textContent =
      "The category you’re looking for doesn’t exist or is no longer available. Try searching for what you need.";
  } else {
    // Default to Page Not Found
    errorTitle.textContent = "Oops! Page Not Found";
    errorMessage.textContent =
      "The page you are looking for might have been moved or deleted. Try searching below.";
  }
</script>

Here is one language editor:

The JavaScript in the code finds the route and shows an error message as per the product, category another page. If you need a similar design, then you need to select a different language in the Language editor and enter a different value as per language.

Add Google Analytics Tracking

To monitor the 404 errors on your site:

Use Google Analytics to track 404 errors.
Set up a custom report for pages with the “404 Not Found” response.
Add a tracking script to the 404 page to log user behavior. Example:

<script>
    // Google Analytics event tracking
    gtag('event', '404_error', {
        'page_path': window.location.pathname
    });
</script>

Best Practices for a 404 Page

Provide Helpful Suggestions: Include links to your homepage, categories, or popular products.
Apologize for the Inconvenience: Acknowledge the error with a friendly, empathetic text.
Use Humor or Branding: Lighten the mood with creative messaging that reflects your brand’s personality.
Include a Call-to-Action: Guide users back to the shopping experience with CTAs like “Continue Shopping” or “Search Our Store.”

Conclusion

Customizing the 404 Not Found page in OpenCart is an effective way to improve user experience and reduce bounce rates. By adding helpful navigation tools, engaging content, and personalized branding, you can turn an error page into an opportunity to retain potential customers and guide them back into your store.

Opencart migration – How to copy the Opencart website to another URL? or transfer to another hosting?

Opencart migration – How to copy the Opencart website to another URL? or transfer to another hosting?

Transferring an OpenCart website to a new domain requires careful planning and execution to maintain its functionality, SEO, and data integrity. Copying a website to another host can be daunting, especially if you have never done it before. However, with the right steps, it can be a straightforward process. Here are the steps that we follow mostly when we have to copy a website to another host. Below is an expanded, detailed step-by-step guide:

Step 1: Backup Your Website

Backup Files:
- Log in to your hosting and go to the root folder where opencart is installed. If you are using cPanel, log in >> public_html
  
  In the above list, you can be different, like mine is wpadmin, yours can be admin, and you may not have vqmod, upload, so it depends on your settings and configuration.
- From the root folder, open config.php
  
  define(‘DIR_OPENCART’, ‘/home3/webocreation/public_html/’);
  Look at the path of DIR_OPENCART and download all the files and folders inside the public_html folder.
  
  define(‘DIR_STORAGE’, ‘/home/webocreation/23storage/’);
  Check the DIR_STORAGE and you need to download all of the files and folders inside the path /home/webocreation/23storage/ except the cache and logs folder. Sometimes cache has lots of files, so you can ignore them as they will be automatically generated.
- Use an FTP client like FileZilla or your hosting control panel to download all files from your current website directory
Backup Database:
- In the config.php, look for the constant DB_DATABASE and see which database is connected to it.
  define(‘DB_DATABASE’, ‘webocreation_demo3’);
  Here, webocreation_demo3 is the database connected.
- Access phpMyAdmin, select your OpenCart database, and export it as an SQL file.
- Ensure you select both “structure” and “data” while exporting.

Step 2: Set Up the New Domain

SSL Certificate: Install an SSL certificate for the new domain to enable HTTPS.
Read more: Install a free SSL certificate on Opencart Let’s Encrypt™
Hosting Environment: Ensure the new domain has a hosting environment compatible with OpenCart’s requirements (PHP version, database type, etc.).

OpenCart Version	Minimum PHP Version	Recommended PHP Version
OpenCart 1.5.x	PHP 5.2.4+	PHP 5.4
OpenCart 2.0.x	PHP 5.3.10+	PHP 5.6
OpenCart 2.3.x	PHP 5.4+	PHP 5.6
OpenCart 3.0.x	PHP 5.6+	PHP 7.1
OpenCart 3.0.3.7+	PHP 7.1+	PHP 7.4
OpenCart 4.x	PHP 8.0+	PHP 8.1 or PHP 8.2

Recommendation: Keep both OpenCart and PHP versions up to date to avoid compatibility or security issues.

Step 3: Upload Files to the New Domain

Use an FTP client or hosting control panel to upload the backed-up files to the root directory (public_html) or the appropriate folder.
Verify that all files have been uploaded correctly, ensuring no files are missing.
Make sure you uploaded the storage folder files and the folder as well.

Step 4: Import the Database to the New Server

Create a New Database:
- Log in to your new hosting control panel.
- Create a new database, user, and password for the website.
Import the Database:
- Open phpMyAdmin, select the new database, and import the SQL file you exported earlier.

Step 5: Update Configuration Files

Update config.php (Root Directory):
- Open the config.php file and update the domain, directory paths, and database details:
Update admin/config.php (Admin Directory):
- Update the admin URLs and paths similarly in admin/config.php.

<?php
// APPLICATION
define('APPLICATION', 'Catalog');

// HTTP
define('HTTP_SERVER', 'https://demo.webocreation.com/');

// DIR
define('DIR_OPENCART', 'YOURNEW_ROOT_FOLDER');
define('DIR_APPLICATION', DIR_OPENCART . 'catalog/');
define('DIR_EXTENSION', DIR_OPENCART . 'extension/');
define('DIR_IMAGE', DIR_OPENCART . 'image/');
define('DIR_SYSTEM', DIR_OPENCART . 'system/');
define('DIR_STORAGE', 'YOURNEWSTORAGE_FOLDER_PATH');
define('DIR_LANGUAGE', DIR_APPLICATION . 'language/');
define('DIR_TEMPLATE', DIR_APPLICATION . 'view/template/');
define('DIR_CONFIG', DIR_SYSTEM . 'config/');
define('DIR_CACHE', DIR_STORAGE . 'cache/');
define('DIR_DOWNLOAD', DIR_STORAGE . 'download/');
define('DIR_LOGS', DIR_STORAGE . 'logs/');
define('DIR_SESSION', DIR_STORAGE . 'session/');
define('DIR_UPLOAD', DIR_STORAGE . 'upload/');

// DB
define('DB_DRIVER', 'mysqli');
define('DB_HOSTNAME', 'localhost');
define('DB_USERNAME', 'YOURNEWUSERNAME');
define('DB_PASSWORD', 'YOURNEWPASSWORD');
define('DB_DATABASE', 'YOURNEWDATABASE');
define('DB_PORT', '3306');
define('DB_PREFIX', 'oc_');

See the config.php and change to the new values which is highlighted.

Step 6: Update Domain References in the Database

Access phpMyAdmin and run the following queries:
- Update the old domain to the new one:
  UPDATE `oc_setting` SET `value` = REPLACE(`value`, 'http://olddomain.com', 'https://newdomain.com');
  Repeat for HTTPS:
  UPDATE `oc_setting` SET `value` = REPLACE(`value`, 'https://olddomain.com', 'https://newdomain.com');
- Update the oc_store table:
  UPDATE `oc_store` SET `url` = 'https://newdomain.com/';
  
  *** oc_ is the database table prefix

Step 7: Update SEO URLs

Open the .htaccess file and verify the RewriteBase: RewriteBase /
Check and regenerate SEO-friendly URLs from the OpenCart admin panel under Design > SEO URLs.

Step 8: Update Email Settings

If your email settings are domain-specific, update them under:
- Admin Panel → Settings → Mail tab.
Ensure the SMTP details are correctly configured for the new domain.

Step 9: Test the Website

Visit the new domain and test:
- Navigation, product listings, and category pages.
- Add-to-cart functionality, checkout, and payment gateways.
- Admin login and backend functionalities.
- Ensure all images and CSS/JS files load correctly.
Clear the OpenCart cache.
Opencart launching checklist

Step 10: Set Up 301 Redirects for the Old Domain

Log in to the old domain’s hosting panel.
Edit the .htaccess file to redirect all traffic to the new domain: Redirect 301 / https://newdomain.com/
Test the redirection to ensure it works properly.

Step 11: Notify Search Engines

Google Search Console:
- Use the “Change of Address” tool to notify Google about the new domain.
Resubmit Sitemap:
- Generate a new sitemap in OpenCart and submit it to Google Search Console and other search engines.

Step 12: Update External Links

Update all external links pointing to your website, including:
- Social media profiles.
- Affiliate sites or partners.
- Email marketing campaigns.

Step 13: Update DNS Records

Update your domain’s DNS records to point to the new server.
Ensure the new domain’s DNS is propagated correctly by using tools like WhatsMyDNS.

Step 14: Monitor Traffic and Performance

Google Analytics:
- Update your Google Analytics property with the new domain URL.
Conversion Tracking:
- Verify all tracking pixels (Google Ads, Facebook Ads, etc.) are working for the new domain.

Step 15: Notify Customers

Send an email to your customer base announcing the domain change.
Highlight the new domain benefits, such as improved performance or security.

Step 16: Perform Final Checks

Conduct a full end-to-end test by placing a few test orders.
Monitor server logs to ensure no broken links or errors are occurring.
After completion of the transfer, don’t forget to go through the Opencart launching checklist to happily launch and check if you forgot something.

Conclusion

Transferring an OpenCart website to a new domain requires careful planning and attention to detail. By following this guide, you can ensure a seamless transition while preserving your site’s functionality, SEO rankings, and user experience. Regularly monitor the new domain post-transfer to address any unforeseen issues promptly.
