【问题描述】：
我正在为 wordpress 使用一个名为 gridby 的主题，当 fb_video 字段包含帖子编辑器中的链接并在博客提要页面中显示视频图像时，它使用自己的插件将特色图像更改为 vimeo 或 youtube 的 iframe和帖子中的 iframe 而不是特色图片。到目前为止，我只将它用于 vimeo 链接，它工作正常，今天只是尝试放入一个带有 /embed 的 youtube 视频链接，并且没有并且仍然显示错误。它不是我的代码，所以如果有人可以帮助我变得很棒，因为我需要这个功能，所以不想进一步刹车。我将 iframe 放入编辑器中的空白帖子中，显示效果很好，只是没有通过 PHP 代码显示。
