提前感谢所有花时间回复的人。So here is what I am trying to achieve: 本质上，我试图创建一个插件，从插件管理页面编辑我页面上的所有元描述。

我使用以下逻辑来实现这一点-在一个页面上打印数据库中的所有元。使用jQuery AJAX从所述页面获取所有页面ID和值。提交时-将所有更新的值推送到数据库中各自的位置，并更新这些元描述。

我不确定我是否在概念层面上有缺陷的代码，或者只是缺少一些基本的东西，但下面是我编写的代码。我试过阅读和测试我能做的一切，但都没有用。任何启示都是非常有益的。

请注意，我的回调函数有三个foreach循环，它们都不起作用，但我留下了它们，以便您可以看到我尝试过的一些东西。

再次感谢！
