How to use add_settings_error in register_setting callback

2 Views
public function database_name_check($input){
    //debug
    add_settings_error('notice', 'lol', 'lol');
    if($this->wpdb->get_var($this->wpdb->prepare('SHOW DATABASES LIKE %s', $input)) == $input)
        return $input;
    else{
        add_settings_error('notice', 'lol', 'lol');
        return FALSE;
    }
}

I can not understand why the error does not exceed, any suggestions?

  1. Take a look at the add_settings_error prototype.

    add_settings_error( $setting, $code, $message, $type );

    The first argument is your settings name/key — or if your setting is on another page (eg general) it should be the page key. The second is whatever you’d like to add to the ID attribute, then error/updated message, and finally type. It doesn’t work because you’re using it incorrectly.

    So you probably want…

    <?php
add_settings_error(
    'your_setting_key', // whatever you registered in `register_setting
    'a_code_here', // doesn't really mater
    __('This is the message itself', 'wpse'),
    'error', // error or notice works to make things pretty
);

    You also need to tell WordPress to display your settings errors. If it’s on a custom page, you’ll need to include settings_errors in the callback.

    settings_errors('your_setting_key');
