How to use deleted_comment action in WordPress

Welcome to our detailed guide on the deleted_comment action in WordPress. This hook fires immediately after a comment is deleted from the database. Using hooks like this ensures your site remains flexible and up-to-date. Let’s dive into how you can use this to enhance your WordPress site.

To use the deleted_comment action, you first need to register it using add_action. You can add this code to your theme’s functions.php file or, preferably, in a custom WordPress Plugin. WePlugins always suggests using a custom plugin to prevent issues during theme updates.

Sometimes, you might want to remove a registered hook, and you can do that easily using remove_action.

Parameters:

• $comment_id: (string) The comment ID as a numeric string.
• $comment: (WP_Comment) The deleted comment.

Example 1: Executing a Function on Comment Deletion

Below is an example of how you can use this hook in your WordPress site.

    function weplugins_execute_on_deleted_comment_event($comment_id, $comment){
        // Code to execute when a comment is deleted
    }
    add_action("deleted_comment", "weplugins_execute_on_deleted_comment_event", 10, 2);
    

Example 2: Removing a Hook Callback

To remove a hook callback, use the example below.

    remove_action("deleted_comment", "weplugins_execute_on_deleted_comment_event", 10, 2);
    

Ensure you provide the same callback function name, priority, and number of arguments when removing the hook.

Example 3: Logging Deleted Comments

Here’s how you could log details of deleted comments for review.

    function weplugins_log_deleted_comment($comment_id, $comment){
        error_log("Comment ID $comment_id deleted: " . print_r($comment, true));
    }
    add_action("deleted_comment", "weplugins_log_deleted_comment", 10, 2);
