让 WordPress 插件在特定事件后工作（例如，当创建草稿帖子时）

我创建了一个 WordPress 插件（在 ChatGPT 的帮助下），它可以重写草稿中的帖子标题，以满足我需要的长度在 36 到 38 个字符之间的标准。目前这是通过单击“自动填充”按钮来实现的，然后让 ChatGPT 重写当前草稿标题，然后检查回复以查看其长度，如果不符合 36-38 个字符的限制，则过程为重复直到完成。然后更改标题并发布帖子。

这工作正常，但是，我试图使其更加自动化，因此不必登录 WordPress 并单击按钮来启动重写过程，只要保存新的草稿帖子，我就希望它，该过程然后自动启动。无论我尝试过什么，我都无法做到这一点，有谁知道我如何实现这一目标？下面是我手动按下按钮时有效的代码

<?php

    'chatgpt_dashboard_page',
    'dashicons-format-chat', // You can change the icon here
    20
  );
}
add_action('admin_menu', 'chatgpt_dashboard_menu');

我尝试创建一个钩子和一个 cron 作业，但我有限的 php 知识无法实现这一点

假设您已经熟悉如何在 WordPress 中正确使用和实现钩子，我建议使用钩子“save_post”。 我就是这样做的：

// Register the hook
add_action('save_post', 'your_function');

// Whatever function you need to be executed
function your_function($post_id) {
    // Check if the post is a draft
    if (get_post_status($post_id) === 'draft') {
       
    }
}

参考： https://developer.wordpress.org/reference/hooks/save_post/

下次，如果你想让更多人愿意阅读并帮助你，请尝试缩短代码并注释它
