我有一个功能正在做一些很棒的功能，当它完成工作时它应该删除一个文件夹但事实并非如此。这是什么以及如何：
这是我挂钩我的功能的地方
add_action('option_after_ajax_save', 'run_custom_function');
这是我的功能
function run_custom_function() {
global $wp_rewrite, $wp_filesystem;
$my_folder = ABSPATH . 'wp-content/themes/' . $themename . '/inc/my-folder/';
//other code
//now once everything else is done and everything works to this point, delete the folder
unlink($my_folder); // I also tried rmdir($my_folder); and it's not working
}
