# "Likes" Hook

 * [11 years, 2 months ago](https://wordpress.org/support/topic/likes-hook/)
 * My site allows users to “Like” other peoples posts.
 * I was wondering how I can use this meta-key;
    _Likes Count
 * I’ve taken the “comment.php” hook and changed all to likes…but nothing is displaying
   in the “points hooks”
 *     ```
       <?php

        * The like points hook class.

        */
   
       // Register the like hook.
       WordPoints_Points_Hooks::register( 'WordPoints_Like_Points_Hook' );
   
       /**

        * @since 1.4.0 No longer subtracts points for like removal.

       	 * such a case it will always return true.

 * The reason why it isn’t working is because most of the important logic is provided
   by `WordPoints_Comment_Approved_Points_Hook_Base` (in `abstracts/comment-approved.
   php`).
 * If you let me know what plugin/theme you are using, I’ll consider creating a 
   module for the plugin that offers this feature.

 * No I didn’t get it. I guess I’ll have to find out what is wrong with my contact
   form. Meanwhile, you will find instructions to contact me here: [http://codesymphony.co/contact/](http://codesymphony.co/contact/)(

 * Hey robint,

    I need to realize the same thing (see
   the newest topic in this support section)
 * Maybe you can help me with that?
