这是我到目前为止的情况。

  function zip_gallery()
  {
      global $post;
      $images = get_children(array(\'post_parent\' => get_the_ID(), \'post_type\' => \'attachment\', \'numberposts\' => -1, \'post_status\' => null, \'post_mime_type\' => \'image\', ));

      if ($images) {
          $save = $post->post_title;

          $zip = new ZipArchive;
          if ($zip->open($save . \'.zip\', ZIPARCHIVE::CREATE) === true) {
              foreach ($images as $image) {
                  $file = wp_get_attachment_url($image->ID, \'full\', false, false);
                  $filename = pathinfo($file);
                  $zip->addFile($file, $filename);
              }

              $zip->close();
          }
      }
  }
