 * I have Wp blog that need to receive a custom paramter on category page for filter
   the posts like my rule.
 * For example: http;//mysite.com/category/teste?myvar=ABC
 * How can I get the myvar from URL? I tried a lot of examples on the web, but no
   one works for the category page.
 * Thanks!

 * Solved with:
 *     ```
       add_filter( 'category_link','append_parameter', 10, 2 );
   
           function append_parameter( $link, $my_parameter ) {
           $my_parameter = $_GET['sort']; //get sort value
           if ( isset($my_parameter) ) {
               $link = add_query_arg( 'sort', $my_parameter, $link );
           }
               return $link;
           }
       ```
