我正在尝试创建一个插件，该插件将通过管理面板（wp admin/edit tags.php）从数据库中删除有关删除自定义帖子（sp\\U场馆）的图片和其他信息

在插件中，我使用它来捕捉事件：

add_action( \'delete_post\', \'kg_delete_post\' );

function kg_delete_post($postId) {

    $post = get_post($postId);

    if ($post->post_type != \'attachment\') {
        return false;
    }

    $url = str_replace($dirs[\'baseurl\'],\'\',$post->guid);
    $urlParts = explode("/",$url);
    $numberOfParts = sizeof($urlParts) - 1;

    $dirs = wp_upload_dir();
    $fileNameParts = explode(".", $urlParts[$numberOfParts]);
    $fileName = str_replace(\'.\' . end($fileNameParts), \'\', $urlParts[$numberOfParts]) . "-*." . end($fileNameParts);
    $path =$dirs[\'basedir\'] ."/".  $urlParts[$numberOfParts-2] . "/" . $urlParts[$numberOfParts-1] . "/";
    $fullPath = $path  . $urlParts[$numberOfParts];
    $fullPathSearch = $path . $fileName;

    @unlink($fullPath);
    foreach (glob($fullPathSearch) as $filename) {
        @unlink($path . $filename);
    }
}

wp_delete_post($Id, true)

我应该用什么来让它工作？非常感谢。
