Q: is registration_errors not triggered ?

Resolved

Hi !

I’m trying to filter email address at register (with the register shortcode) if it doesn’t match certain domain names extensions.

This seems to work fine on native register form,

// Block certain email user registration domain extension
add_filter( 'registration_errors', 'myplugin_check_fields', 10, 3 );
function myplugin_check_fields( $errors, $sanitized_user_login, $user_email ) {

    $retval = preg_match( '/(.+)@(\S+)\.(\w+)/', $user_email, $matches );
    
    $allowed = ["fr", "com", "net"];
    
    if( $retval !== 1 || !isset($matches[3]) || !in_array($matches[3], $allowed ) ) {
        $errors->add( 'demo_error', __( '<strong>ERROR</strong>: User email domain extension not allowed.', 'my_textdomain' ) );
        $errors->add_data( 'demo_error', __( '<strong>ERROR</strong>: User email domain extension not allowed.', 'my_textdomain' ) );
    }
    
    return $errors;
}

(elaborated from https://codex.ww.wp.xz.cn/Plugin_API/Filter_Reference/registration_errors )

But not on the one generated by this plugin. It is as if the filter wasn’t triggered.

Is registration_errors hook triggered bu this plugin ?

Thx for your support !

Hi @x-raym,

Yes, we do not trigger code hooks. We have our own hook to validate fields. Please use the following code for your purpose.

function ur_validate_email_field( $single_form_field, $data, $filter_hook, $form_id ) {

	if ( absint( $form_id ) === 1 ) { // Your form ID to restrict.

		$user_email      = strtolower( $data->value );
		$retval  = preg_match( '/(.+)@(\S+)\.(\w+)/', $user_email, $matches );
		$allowed = [ 'fr', 'com', 'net' ];

		if ( $retval !== 1 || ! isset( $matches[3] ) || ! in_array( $matches[3], $allowed ) ) {
			add_filter(
				$filter_hook,
				function ( $msg ) {
					return __( 'User email domain extension not allowed.', 'user-registration' );
				}
			);
		}
	}
}
add_action( 'user_registration_validate_user_email', 'ur_validate_email_field', 10, 4 );

Regards!

@rumesh38 Many thanks for the quick answer and updated code snippet !

I’m curious though, why not using native hooks ?
It makes porting from my old registration plugin to this one a bit more complex,
and it can bring extensibility down by not allowing other plugin to hook regular filters. :/

At least we have a workarround sure but extensibility ane interoperability are core of WordPress.
