Hi i trying to call the php reset function in ajax but when i googling i know that not possibilities of direct calling php function so I put that particular function in seperate php file and call that php file i am not sure how can i do this in ajax i tried this above code but nothing happen. Settings Resets Message appear. How Can I do this Any Help would be great. Before using the ajax concept i tried with issetfunction in php But it getting page load every time for that only i jump into the ajax.
嗨，我试图在 ajax 中调用 php reset 函数，但是当我使用谷歌搜索时，我知道直接调用 php 函数的可能性不大，所以我将该特定函数放在单独的 php 文件中并调用该 php 文件，我不知道如何在ajax 我试过上面的代码，但没有任何反应。出现设置重置消息。我该怎么做 任何帮助都会很棒。在使用 ajax 概念之前，我尝试isset在 php 中使用函数，但每次都会加载页面，只有我跳入 ajax。

There is a standard way of achieving AJAX in WordPress plugin by relying on the admin_ajax.php. The file name is misleading, as it can be used in the frontend too, by assigning functions to AJAX actions.
有一种标准的方式可以通过 admin_ajax.php 在 WordPress 插件中实现 AJAX。文件名具有误导性，因为它也可以通过将函数分配给 AJAX 操作在前端使用。
There is a good description on the WordPress Codex:
WordPress Codex 上有很好的描述：
http://codex.wordpress.org/AJAX_in_Plugins
http://codex.wordpress.org/AJAX_in_Plugins
One thing to be aware of: Your AJAX handler functions will always have to terminate with a die()command, to avoid the extra '0' output from WordPress.
需要注意的一件事：您的 AJAX 处理程序函数将始终必须以die()命令终止，以避免来自 WordPress 的额外“0”输出。
