 * Hello everybody,
 * Can anybody tell me where the value of $PHP_SELF comes from. Most of the times
   is blank and is causing me troubles in some of my pages. I’m using the next form
   in my side bar
 *     ```
       <form action="<?php echo $PHP_SELF ?>" method="get">
       ...
       </form>
       ```
   
 * To displays the categories using the function wp_dropdown_categories(), but only
   works in the main template. When I’m under another template (ie: single post,
   search results) the form doesn’t work.
 * Should I change the value of the action parameter to my main page?
 * Thanks a lot.
