How to use MailboxValidator API to validate email in PrestaShop

Overview #

PrestaShop is a popular e-commerce platform used by merchants worldwide. It comes packed with features to assist merchants in their daily business operations. However, some built-in features offer only basic functionality. Take email validation, for example: PrestaShop only checks basic rules, such as whether the email field is empty or if the address follows a valid format (e.g., user@example.com).

What if you want to block disposable email addresses during account registration? Registering with a temporary email address often indicates suspicious activity due to the anonymity it provides.

To solve this problem, PrestaShop allows you to extend or enhance built-in features using a mechanism called Override. In this article, we will show you how to extend the default form validation to block invalid and disposable email addresses using the MailboxValidator API.

Note: Before making any modifications, please back up your project.

Registration form #

To extend the registration form:

1. Create a new file named CustomerForm.php under web project root/override/classes/form.
2. Open the newly created file and paste the following code into it:

<?php

class CustomerForm extends CustomerFormCore
{
    public function validate()
    {
        $apikey = your_MailboxValidator_API_key;
        $results = file_get_contents('https://api.mailboxvalidator.com/v1/validation/single?key=' . $apikey . '&email=' . $this->getField('email')->getValue() . '&source=prestashop');
        $results = json_decode($results);
        if ($results->status == 'False') {
            $this->getField('email')->addError($this->translator->trans(
                'Please enter a valid email address.',
                array(),
                'Shop.Notifications.Error'
            ));
        }
        parent::validate();
   }
}

3. Finally, navigate to web project root/var/cache/dev (if in development mode), or your web project root/var/cache/prod (if in production mode)and delete the class_index.php file. This manually clears the cache so your changes take effect immediately.
4. Go to the registration form, enter an invalid email address, and test the result. You should see the error message appear.

Contact form #

To extend the contact form:

1. Create a new file named contactform.php under web project root/override/modules/contactform.
2. Open the newly created file and paste the following code into it:

<?php

Class ContactformOverride extends Contactform
{
    public function sendMessage()
    {
        if ($from = trim(Tools::getValue('from'))) {
            $apikey = your_MailboxValidator_API_key;
            $results = file_get_contents('https://api.mailboxvalidator.com/v1/validation/single?key=' . $apikey . '&email=' . $from . '&source=prestashop');
            $results = json_decode($results);
            if ($results->status == 'False') {
                $this->context->controller->errors[] = $this->trans(
                    'Please enter a valid email address.',
                    [],
                    'Shop.Notifications.Error'
                );
            }
            parent::sendMessage();
        }
    }
}

3. Finally, navigate to web project root/var/cache/dev (if in development mode), or your web project root/var/cache/prod (if in production mode)and delete the class_index.php file. This manually clears the cache so your changes take effect immediately.
4. Go to the registration form, enter an invalid email address, and test the result. You should see the error message appear.
