PrestaShop Captcha Module installation and integration tutorial:

Step 1

Set up your Google reCAPTCHA account at https://www.google.com/recaptcha

Label: indicative name for the reCAPTCHA

Domains: indicate your domain name in the form "my-prestashop-store.com"

You will then have the API keys provided by Google!

Step 2

Download and install the PrestaShop Captcha Module.

Step 3

Configure the PrestaShop Captcha Module in the back office (your admin area)

and paste the public and secret keys provided by Google reCAPTCHA.

Step 4

Open the file www/themes/my-theme/contact-form.tpl and look for the following code (line 148 for PrestaShop 1.6.1.6):

							 <div class="submit">
<button type="submit" name="submitMessage" id="submitMessage" class="button btn btn-default button-medium"><span>{l s='Send'}<i class="icon-chevron-right right"></i></span></button>
</div>
							 

Paste the following code just before replacing "YOUR_PUBLIC_KEY" with your public key provided by Google reCAPTCHA:

							 {if $captcha}
<script src='https://www.google.com/recaptcha/api.js'></script>
<div class="g-recaptcha" data-sitekey="YOUR_PUBLIC_KEY"></div>
{/if}
							 

Save the file and send it back to the server using your FTP client.

Step 5

Open the file /controllers/front/ContactController.php

and just after this line:

$this->errors[] = Tools::displayError('Bad file extension');

add:

} else if (!($gcaptcha = (int)(Tools::getValue('g-recaptcha-response')))){

$this->errors[] = Tools::displayError('Captcha not verified');

}

Step 6

Refresh your Contact page and enjoy the result!
