  1. Hi,

    Thanks for the sharing. I have an issue with OC 2.3.0.2. After enabled with google recaptcha and applied to the contact form but it doesn’t work. I can see the google captcha “I am not Robot” appear but it simply doesn’t work and bypass it no matter you have authenticating it or not. Do you have any idea? I have checked the catalog/controller/information/contact.php the google reCaptcha seems no code applying in there. Can you help please?

    Thanks,

    Paul

    • Hi @Paul,

      In catalog/controller/information/contact.php you can find the code implemented in the validate method.
      ==================
      protected function validate() {
      if ((utf8_strlen($this->request->post[‘name’]) < 3) || (utf8_strlen($this->request->post[‘name’]) > 32)) {
      $this->error[‘name’] = $this->language->get(‘error_name’);
      }
      if (!filter_var($this->request->post[’email’], FILTER_VALIDATE_EMAIL)) {
      $this->error[’email’] = $this->language->get(‘error_email’);
      }
      if ((utf8_strlen($this->request->post[‘enquiry’]) < 10) || (utf8_strlen($this->request->post[‘enquiry’]) > 3000)) {
      $this->error[‘enquiry’] = $this->language->get(‘error_enquiry’);
      }
      // Captcha
      if ($this->config->get($this->config->get(‘config_captcha’) . ‘_status’) && in_array(‘contact’, (array)$this->config->get(‘config_captcha_page’))) {
      $captcha = $this->load->controller(‘extension/captcha/’ . $this->config->get(‘config_captcha’) . ‘/validate’);
      if ($captcha) {
      $this->error[‘captcha’] = $captcha;
      }
      }
      return !$this->error;
      }
      ==================
      Please verify yout secret key and site key again.

  2. Hello Rupak,

    Thanks for the reply. Yes I double checked I have all exact the same coding in the contact.php. Actually I refreshed the module modification and it works now. Not sure if were related but I am glad it is resolved. Thanks you for great help and excellent site.
