Pow Captcha for PrestaShop

This plugin allows you to validate the contact form using Pow Captcha. Tested on PrestaShop 1.6 to 8.1.

Requirements

PHP 7.1+ and php_curl is needed to use this module.

Installation

PrestaShop 1.7+

For PrestaShop 1.7+, require the plugin with Composer using the following command:

composer require aeyoll/pow_captcha

PrestaShop 1.6

For Prestashop 1.6, this minimum composer.json file is required at the root of your project.

{
    "name": "project-name/project-name",
    "require": {
        "aeyoll/pow_captcha": "dev-main",
        "composer/installers": "^1.0.21"
    },
    "config": {
        "allow-plugins": {
            "composer/installers": true
        },
        "sort-packages": true
    },
    "minimum-stability": "dev"
}

Then, you need to override this Controller class (classes/controller/Controller.php), so the actionControllerInitAfter is called:

/**
  * Initialize the page
  */
public function init()
{
    if (_PS_MODE_DEV_ && $this->controller_type == 'admin') {
        set_error_handler(array(__CLASS__, 'myErrorHandler'));
    }

    if (!defined('_PS_BASE_URL_')) {
        define('_PS_BASE_URL_', Tools::getShopDomain(true));
    }

    if (!defined('_PS_BASE_URL_SSL_')) {
        define('_PS_BASE_URL_SSL_', Tools::getShopDomainSsl(true));
    }

    // Override
    Hook::exec(
        'actionControllerInitAfter',
        [
            'controller' => $this,
        ]
    );
    // /Override
}

Usage

In each form template, add the following above the submit button:

{hook h='displayBeforeContactFormSubmit' m='pow_captcha'}
