 * I have a one problem about my website . I have tried a lot of ways for fix it
   but I could not find a solution.
 * I use query_vars parameters in [that pages oyna ](http://www.soloyun.com)and 
   there isn’t any problem. But i don’t use different parameters or the same parameters
   in different custom page. Parameter value is always empty.

 * Did you put this in your theme’s functions.php:
 *     ```
       function parameter($qvars)
       {
       $qvars[] = 'kategori';
       $qvars[] = 'ara';
       $qvars[] = 'numara';
       $qvars[] = 'tur';
       return $qvars;
       }
       add_filter('query_vars', 'parameter');
       ```
   
 * try it with:
 *     ```
       $tur = get_query_var('tur');
       echo $tur;
       ```
