How to use edit_post action in WordPress

edit_post action

Fires once an existing post has been updated.

To use edit_post action, first you have to register it using add_action. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function execute_on_edit_post_event which takes 2 parameters and we registered using add_action. The first parameter edit_post is the name of the hook, the second parameter execute_on_edit_post_event is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_action to remove edit_post action.

Parameters

Below are the 2 parameters required to use this hook.

• $post_ID : (int) Post ID.
• $post : (WP_Post) Post object.

Live Example 1

Below is an example of how you can use this hook.

    function weplugins_execute_on_edit_post_event($post_ID, $post) {
        // You can write code here to be executed when this action occurs in WordPress.
        // Use the parameters received in the function arguments & implement the required additional custom functionality according to your website requirements.
    }
    // Add the action
    add_action("edit_post", "weplugins_execute_on_edit_post_event", 10, 2);
    

Live Example 2

To remove a hook callback, use the example below.

    remove_action("edit_post", "weplugins_execute_on_edit_post_event", 10, 2);
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Live Example 3

Here’s another example where we send an email notification every time a post is updated.

    function weplugins_notify_on_post_update($post_ID, $post) {
        $author_email = get_the_author_meta('user_email', $post->post_author);
        wp_mail($author_email, "Post Updated", "Your post has been updated.");
    }
    // Add the action
    add_action("edit_post", "weplugins_notify_on_post_update", 10, 2);
