Comment Author Checklist


This new template tag generates a list of registered users. The post author and users who have commented on the post are crossed off the list; any users who have not yet commented are left alone.


  • exclude the admin user
  • choose the minimum user role to be show in the list (e.g. Contributor, Author, etc.)
  • sort the list by user ID, display name, first name, last name, or login
  • choose the categories in which to show the list

This plugin requires PHP 5.10.


Installation is pretty standard:


  1. Upload comment-author-checklist.php to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Place <?php if (function_exists('show_comment_author_checklist')) show_comment_author_checklist(); ?> inside the Loop in the template file of your choice (usually single.php).

Example: <?php the_content(); ?>


I can’t get the plugin to show anything.

Check your PHP version. The plugin requires 5.10.
