Good day,

I have tried the following approaches to block spammers from creating further accounts but unfortunately nether of the 2 approaches worked.

Users are still able to create accounts as per normal so I believe either you have custom actions or shortcodes that I am missing.

Can you please assist me, the code I tried is below.

add_action('woocommerce_register_post','is_valid_registration_email_domain', 10, 3 );
function is_valid_registration_email_domain( $username, $email, $validation_errors ){
    $valid_email_domains = array( 'gmail.com', 'yahoo.com' ); // Allowed domains
    $valid = false; // sets default validation to false
    foreach( $valid_email_domains as $d ){
        $d_length = strlen( $d );
        $current_email_domain = strtolower( substr( $email, -($d_length), $d_length));
        if( $current_email_domain != strtolower($d) ){
            $valid = true;
            break;
        }
    }

    // Return error message for invalid domains
    if( ! $valid ){
        $error_text = __( "<strong>ERROR</strong>: Registration is only allowed from selected approved domains. If you think you are seeing this in error, please contact the system administrator.", "woocommerce" );
        $validation_errors->add( 'domain_whitelist_error', $error_text );
    }
}

// Allow Registration Only from @warrenchandler.com email addresses

function is_valid_email_domain($login, $email, $errors ){
 $valid_email_domains = array("warrenchandler.com","warrenchandler.co.uk");// allowed domains
 $valid = false; // sets default validation to false
 foreach( $valid_email_domains as $d ){
  $d_length = strlen( $d );
  $current_email_domain = strtolower( substr( $email, -($d_length), $d_length));
 if( $current_email_domain != strtolower($d) ){
  $valid = true;
  break;
 }
 }
 // Return error message for invalid domains
 if( $valid === false ){

$errors->add('domain_whitelist_error',__( '<strong>ERROR</strong>: Registration is only allowed from selected approved domains. If you think you are seeing this in error, please contact the system administrator.' ));
 }
}
add_action('register_post', 'is_valid_email_domain',10,3 );

Hello, Dominus,

Thank you for contacting us and for using XStore.

Please note that additional customization in files is out of our basic support scope.

We have developed the following functions for you, simply add them to the functions.php of the child theme.
Note: if you are using additional plugins for user registration, the sent functions may not work.

if (! function_exists('et_validate_registration_by_email_domain')){
    // Hook into the registration_errors action (To prevent default WordPress registration)
    add_action('registration_errors', 'et_validate_registration_by_email_domain', 10, 3);

    function et_validate_registration_by_email_domain($errors, $sanitized_user_login, $user_email) {
        // Define the list of allowed email domains
        $allowed_domains = array('gmail.com', 'yahoo.com');

        // Extract the domain part of the email address
        $user_email_parts = explode('@', $user_email);
        $user_domain = strtolower(end($user_email_parts));

        // Check if the user's email domain is in the allowed list
        if (!in_array($user_domain, $allowed_domains)) {
            $errors->add('email_domain_not_allowed', __('Registration is allowed only with specific email domains.', 'xstore-child'));
        }

        // Return the modified errors object
        return $errors;
    }
}

if (! function_exists('et_wc_validate_registration_by_email_domain')){
    // Hook into the woocommerce_new_customer_data filter (To prevent WooCommerce registration)
    add_filter('woocommerce_new_customer_data', 'et_wc_validate_registration_by_email_domain', 10, 1);

    function et_wc_validate_registration_by_email_domain($customer_data) {
        // Define the list of allowed email domains
        $allowed_domains = array('gmail.com', 'yahoo.com');

        // Get the email address from the customer data
        $user_email = $customer_data['user_email'];

        // Extract the domain part of the email address
        $user_email_parts = explode('@', $user_email);
        $user_domain = strtolower(end($user_email_parts));

        // Check if the user's email domain is in the allowed list
        if (!in_array($user_domain, $allowed_domains)) {
            throw new Exception(__('Registration is allowed only with specific email domains.', 'xstore-child'));
        }

        // Return the modified customer data
        return $customer_data;
    }
}

Kind Regards,
