Wordpress Admin - required custom meta check

Question

I\'m adding custom user meta in wordpress admin, and I would like my two custom fields are required, but how I show error and tell wordpress to not update profile if error ?

I think you can try this

add_action('user_profile_update_errors', 'validate_extra' 10, 3);
function validate_extra(&$errors, $update = null, &$user  = null)
{
    if (is_super_admin())
    {
        if (!$_POST['country'] || !$_POST['timezone'])
        {
            $errors->add('empty_country', "ERROR: Please select a country in the list");
        }   
        
    }
}

add_action( 'personal_options_update', 'save_extra_profile_fields' );
add_action( 'edit_user_profile_update', 'save_extra_profile_fields' );
function save_extra_profile_fields($user)
{
    if (is_super_admin())
    {
        update_user_meta($user, 'country', $_POST['country']);
        update_user_meta($user, 'timezone_string', $_POST['timezone']);
    }
}
