I have validate the custom field in registration form, I read out the codex of wordpress so that itself i do this way. But I figure out it throws error like this one
Call to a member function add() on a non-object
I don't know why this should happen. How can I fix this? Any Suggestion would be great.
Code:
function myplugin_check_fields($errors, $sanitized_user_login, $user_email) {
$errors->add( 'demo_error', __('<strong>ERROR</strong>: This is a demo error. Registration halted.','mydomain') );
return $errors;
}
add_filter('registration_errors', 'myplugin_check_fields', 10, 3);
