我认为没有函数。但你可以这样创造你自己的

function function_name(){

    global $new_whitelist_options;
    
    // array of option names
    $option_names = $new_whitelist_options[ \'your_option_group_name\' ];

    // your_option_group_name is in register_setting( \'your_option_group_name\', $option_name, $sanitize_callback ); 
    foreach ($option_names as $option_name) {
        echo get_option($option_name).\'<br>\';
    }
    

}
