Trzeba robić różne rzeczy. Ale możesz zmienić haczyk, którego używa Ultimate Member. Używają klasy Validation. Ale pamiętając o swoich potrzebach, możesz ominąć użycie tej klasy. To jest rozwiązanie, które myślę, że zadziała

remove_action( 'um_submit_form_register', 'um_submit_form_register', 10 );

Teraz zarejestrujemy nową metodę.

add_action( 'um_submit_form_register', 'my_custom_submit_form_register', 10 );

Oto funkcja. Myślę, że programiści muszą zrobić w następnej wersji, aby zapewnić filtr wewnątrz klasy Validation.

function my_custom_submit_form_register( $args ) {
    if ( isset( UM()->form()->errors ) ) {
        return false;
    }

Nic nie zmieniałem, tylko dodałem filtr, więc nie ma problemu, jeśli programiści coś zmienią (będziesz miał problemy, jeśli programiści dodadzą do tego nowe rzeczy, w przeciwnym razie sięgnę do nich, aby dodać filtr). Oto filtrowana funkcja.

function my_custom_password_strength() {
    global $ultimatemember;
    $password = $_POST['user_password-257'];

     if (preg_match(" /^(?=.*[!@#$%^&*-])(?=.*[0-9])(?=.*[A-Z]).{8,20}$/", $password)) {
             return wp_generate_password(8)
        } else {
            $ultimatemember->classes['form']->add_error( 'user_password-257', __('Your password must have a special character') );
            do_action('um_user_registration', $args); 
        }
}

Tylko w ten sposób możesz to zrobić. Być może będziesz musiał dodać jeszcze kilka czeków. Ale pamiętaj, aby po prostu bawić się funkcją filtrowania my_custom_password_strength().

Mam nadzieję że to pomoże. Dzięki
