我得到了WordPRess插件的以下代码，它在每个页面/后期编辑屏幕上添加了两个自定义输入。然后将这些值保存并输出到前端页面的标题中。
如果代码位于内部，则可以正常工作。php文件并直接放入“wp内容/插件”。然而，如果我把它放在插件（如“wp-content/plugins/myplugin”）中自己的文件夹中，那么在通过编辑屏幕保存帖子/页面时，输入字段不会保存。此外，它不会向前端页面html标题部分输出任何内容。
这似乎是一个被放弃的项目，所以我无法与原始开发人员一起制定解决方案。然而，代码中的某些内容似乎需要更新，以反映代码被放置在插件文件夹中。
这是代码。。。。。

下面是修复和修改后的代码，该代码存在nonce操作问题。
