 * Just started making inroads into coding my first plugin. I’ve got a widget that
   displays three tabs of post titles in a tabbed menu. The first tab currently 
   displays the most commented posts written in the last 30 days. I’m using this
   filter:
 *     ```
       $where .= " AND post_date > '" . date('Y-m-d', strtotime('-30 days')) . "'";
       ```
   
 * I’d like to make the 30 days a user configured variable but don’t know how to
   echo this variable within the where filter.
 * How can I make it work?
