email field validation

Hi @jpgoem

Hope this message finds you well.

Currently, there is no option to customize the email validation, however, our developers coded a snippet to check a list of forbidden domains:

add_filter( 'forminator_custom_form_submit_errors', function( $submit_errors, $form_id, $field_data_array ){

	$email_field = 'email-1';
	$forbitten_public_emails = array( 'gmail', 'yahoo' );

	$email = isset( $_POST[ $email_field ] ) ? $_POST[ $email_field ] : false;
	if ( ! $email ) {
		return $submit_errors;
	}

	list( $user, $domain ) = explode( '@', $email );

	foreach ( $forbitten_public_emails as $forbitten_public_email ) {

		if ( strpos( $domain, $forbitten_public_email ) !== false ) {
		    $submit_errors[][ $email_field ] = __( 'Please avoid using gmail, yahoo etc and use a private email instead' );
		    break;
		}

	}

	return $submit_errors

You will need to update these lines:

$forbitten_public_emails = array( 'gmail', 'yahoo' );

Replace gmail, yahoo, with the domains you want to block or verify.

$email_field = ’email-1′;

Replace the email-1 with your form email field tag.

You might need to install it as a mu-plugin following the instructions on this link https://wpmudev.com/docs/using-wordpress/installing-wordpress-plugins/#installing-mu-plugins.

Hi Laura,

I am not looking to exclude “forbidden” domains. Thank you anyway for the research.
