How to integrate Recaptcha in Prestashop in 3 steps
Prestashop is one of the most used ecommerce on the internet BUT the contact form has no protection again the spam. Of course you can buy an additional plugin but I will explain how to integrate a spam protection without paying. You have to create and configure an account, change 2 sources. You can make it in 30 mn or less.
Here is a howto step by step for prestashop 1.6 (I don’t know about prestashop 1.7 but I imagine it should be similar).
1 Setup your Google reCAPTCHA if you don’t have it
https://www.google.com/recaptcha/intro/index.html
Note the key and the secret key
You have to configure it and put your domain name.
2 Change the contact-form.tpl
First you have to change the contact form (client side) contact-form.tpl should be in your theme. Open an editor and search the submit botton
For me it is like that
<div class="submit">
<button type="submit" name="submitMessage" id="submitMessage" class="button"><span>{l s='Send'}<i class="icon-chevron-right right"></i></span></button>
</div>
</form>
Just above add few lines of code. Replace key by your key
<script src='https://www.google.com/recaptcha/api.js'></script> <div class="g-recaptcha" data-sitekey="key"></div>
That should look like that
<div>
<script src='https://www.google.com/recaptcha/api.js'></script>
<div class="g-recaptcha" data-sitekey="key"></div>
</div>
<div class="submit">
<button type="submit" name="submitMessage" id="submitMessage" class="button"><span>
{l s='Send'}
<i class="icon-chevron-right right"></i></span>
</button>
</div>
</form>
3 Change ContactControler.php
If you don’t have this source in override\controllers\front copy it from controllers\front
Then you have to add few lines to check if the captcha is ok or not
search the postProcess() function it should be at the begining (2nd function) and add
if (Tools::isSubmit('submitMessage')) {
$extension = array('.txt', '.rtf', '.doc', '.docx', '.pdf', '.zip', '.png', '.jpeg', '.gif', '.jpg');
$file_attachment = Tools::fileAttachment('fileUpload');
$message = Tools::getValue('message'); // Html entities is not usefull, iscleanHtml check there is no bad html tags.
$id_order = (int)$this->getOrder();
if (!($from = trim(Tools::getValue('from'))) || !Validate::isEmail($from)) {
$this->errors[] = Tools::displayError('Invalid email address.');
// add the 2 lines from here
} elseif (!($gcaptcha = (int)(Tools::getValue('g-recaptcha-response')))) {
$this->errors[] = Tools::displayError('Captcha error');
// to here
