Only accept certain emails in WooCommerce registration

B.A._Baracus

Hi guys,
Wondering if anyone can point me in the right direction to solve this issue. Long story short I need to allow users to signup only using a certain email address (let's say @yourcompany.com email address) in Woocommerce / registration page . if anyone else was to try and signup it would throw an error saying please use your correct email etc.

Any ideas of how to do this?
I was hoping there would be a plugin out there but cannot find one sadly.


cheers.

Here's a code snippet to perform the task in WordPress.

function whitelist_email_check($errors, $sanitized_user_login, $user_email) {
  $whitelisted_domains = array('mydomain.com'); // whitelist email domains
  $valid_email = false;
  foreach ($whitelisted_domains as $valid_domain) {
    $length = strlen($valid_domain);
    $email_domain = strtolower(substr($user_email, -($length), $length));
    if ($email_domain == strtolower($valid_domain)) {
      $valid_email = true;
      break;
    }
  }
  if ($valid_email == false) {
    $errors->add('user_email_error', __('<strong>ERROR</strong>: The email address is not whitelisted.', 'some_textdomain'));
  }
  return $errors;
}

add_filter('registration_errors', 'whitelist_email_check', 10, 3);

WooCommerce provides the woocommerce_register_post hook which takes different parameters ($username, $email, $errors) so you would have to tweak the code slightly.

function wc_whitelist_email_check($username, $user_email, $errors) {
  $whitelisted_domains = array('mydomain.com'); // whitelist email domains
  $valid_email = false;
  foreach ($whitelisted_domains as $valid_domain) {
    $length = strlen($valid_domain);
    $email_domain = strtolower(substr($user_email, -($length), $length));
    if ($email_domain == strtolower($valid_domain)) {
      $valid_email = true;
      break;
    }
  }
  if ($valid_email == false) {
    $errors->add('email_error', __('<strong>ERROR</strong>: The email address is not whitelisted.', 'some_textdomain'));
  }
}

add_filter('woocommerce_register_post', 'wc_whitelist_email_check', 10, 3);

Update the theme's functions.php file with the code snippet. Modify the whitelisted_domains array to check for the required email domains and you should be good to go.
