WordPress的挂钩前发布更新 [英] Wordpress Hook Pre Post Update

问题描述

我正在写一个wordpress插件.如果发布状态为将来，我想将发布状态设置为发布.

I am writing a wordpress plugin. I would like to to set the post status to publish if post status is future.

我知道要使用的一个钩子是pre_post_update.

I know one hook that is to be used that is pre_post_update.

但是，与帖子相关的详细信息数组存储在哪里，以便我可以更改post_status?

However where is the array of post related details stored so that I can change the post_status?

感谢您的帮助

推荐答案

调用pre_post_update挂钩的函数对我来说出现在wp-includes/posts.php的第1525行:

The function that calls the pre_post_update hook appears on line 1525 of wp-includes/posts.php for me:

do_action( 'pre_post_update', $post_ID );

如您所见，它在执行时传递要更新的帖子的ID.要从那里获取帖子，您只需致电get_post()，例如:

As you can see, it passes the ID of the post being updated when it is executed. To get the post from there, you would just call get_post(), e.g.:

function do_something_with_a_post($post_id, $post_data) {
     // now do something with $post_data
}
add_action('pre_post_update', 'do_something_with_a_post', 10, 2);

希望，上面的$post变量应该引用一个对象，该对象具有与您正在寻找的帖子有关的所有各种属性.

The $post variable above should reference an object with all of the various attributes about a post you are looking for, hopefully.
