How to use delete_comment action in WordPress

Alright, so you’re diving into the world of WordPress hooks, and today we’re focusing on the delete_comment action hook. This hook is super handy because it lets you execute custom code right before a comment is deleted from your site’s database. Whether you’re adding this to your theme’s functions.php or creating a custom plugin (which we highly recommend to keep things tidy during theme updates), the delete_comment action is a go-to for developers looking to customize comment deletion behavior.

Example 1: Adding Custom Functionality on Comment Deletion

Here’s a basic example that shows how you can use the delete_comment action. In this snippet, we define a function called weplugins_execute_on_delete_comment_event that performs actions when a comment is about to be deleted.

    function weplugins_execute_on_delete_comment_event($comment_id, $comment){
       // Custom logic here
    }
    // Add the action
    add_action( "delete_comment", "weplugins_execute_on_delete_comment_event" , 10, 2);
    

Example 2: Removing the Action Hook

Sometimes, you might need to remove an action hook. Here’s how you can remove the delete_comment action using remove_action.

    remove_action( "delete_comment", "weplugins_execute_on_delete_comment_event", 10, 2 );
    

Example 3: Logging Deleted Comments

In this example, let’s log the details of a comment right before it’s deleted. This can be useful for auditing or maintaining records.

    function weplugins_log_deleted_comment($comment_id, $comment){
        error_log('Comment ID ' . $comment_id . ' is about to be deleted.');
    }
    add_action( "delete_comment", "weplugins_log_deleted_comment" , 10, 2);
