Disable WP notifications for commenting on own posts

1 comment

1. The function that sends emails to the post author is called wp_notify_postauthor() and is located in /wp-includes/pluggable.php. This means that the function is “pluggable” and can be overridden by another function with the same name. We can make a simple plugin to do this.

   This is the code we’ll be adding to the function to check if the author is posting on his own comment.

   if ( $comment->comment_author_email == $author->user_email ) {
        return false;
   }
   

   And here is the completed plugin for WordPress version 3.6. This needs to be saved in a PHP file called custom-author-notification.php and saved in a folder called custom-author-notification in your plugins directory /wp-content/plugins/.

   <?php
   /*
   Plugin Name: Custom Author Notification
   Description: Stops authors from receiving emails when they comment on their own posts. Replaces the default wp_notify_postauthor() function in WordPress v3.6.
   Version: 1.0
