What is WordPress Hook: pre_post_update

Understanding the Hook: pre_post_update
The pre_post_update hook is located within the wp-includes/post.php file in WordPress. It is called within the wp_insert_post() function, just before the post data is updated in the database. This allows developers to intervene and make changes to the post data before it is saved.
Hook Parameters (if applicable): pre_post_update
The pre_post_update hook accepts two parameters: $post_ID and $data. The $post_ID parameter is the ID of the post being updated, while the $data parameter contains the post data that is about to be updated. Developers can use these parameters to perform actions or modify the post data as needed.
