php - Wordpress - save filter settings into cookie -

i have custom post type in wordpress, custom filters.

i able save user's filter cookie, when comes posts lists, last filter set automatically.

i have code saving cookie:

function set_newuser_cookie() {     if ( is_admin() && $_get['post_type'] == 'tickets') {          setcookie('bs_tickets_filter', $_server['query_string'], time()+3600*24*100, cookiepath, cookie_domain, false);      } } add_action( 'init', 'set_newuser_cookie');  

this code saves whole query string cookie, like:

orderby=status&order=asc&s&post_status=all&post_type=tickets&action=-1&m=0&status=0&type=0&priority=0&state=2135&author&paged=1&mode=list&action2=-1 

how can set filter again, when user comes posts listing?

i think solved this:

function bs_set_filter_cookie() {     if ( is_admin() && $_get['post_type'] == 'tickets' ) {       // if theres filter request, update cookie       if (isset($_get['status'])) {         $query = http_build_query($_get);          setcookie('bs_tickets_filter', $query, time()+3600*24*100, cookiepath, cookie_domain, false);    }   }    // if there's no filter request, add variable $_get   if (!isset($_get['status'])) {      parse_str($_cookie["bs_tickets_filter"], $output);      foreach ($output $key => $val) {         $_get[$key] = $val;      }    } } add_action( 'init', 'bs_set_filter_cookie');
