Invisible Recaptcha

This extension helps easily integrate Invisible reCAPTCHA from Google. Simply install it and configure it by following instructions on this page.

However it doesn't seem to support form that make calls via AJAX. Therefore some further modification needs to be made. Modifications listed below are dirty, but solves the problem quickly.

  • Edit {webroot}/app/design/frontend/base/default/template/amasty/aminvisiblecaptcha/captcha.phtml
  • Find the line that says currentForm.submit();
  • And replace that line with the code below
if ( == 'your-form-id') {
    var data = jQuery('#your-form-id').serialize();
    var url= "<?php echo Mage::app()->getStore()->isCurrentlySecure() ? Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_LINK, true) : Mage::getBaseUrl(); ?>{some/location}";

        url: url,
        dataType: 'json',
        type : 'post',
        data: data,
        success: function(data){
           // some logic
} else {
  • Test your ajax form and enjoy.
