php - How to pass the $_SESSION value after using AJAX -


i trying if-statement respond change in $_session['view'] value, after using ajax filter query results. however, if-statement not nested within ajax div section, rather adjacent , below.

what think need, perhaps function within ajax page call reload of if-statement, thereby checking new $_session['view'] value.

this present structure.

<?php session_start(); ?> <body>     <div class="content">content here          <div class="filters">              <select name="view">view                  <option value="standard">standard</option>                  <option value="gallery">gallery</option>              </select>          </div><!--end filters-->          <div class="show"> ajax results here </div>     </div>     // below displays adjacent div     <?php     $sess == ($_session['view'])     if(!isset($sess)||($sess=='standard')){         echo '<div>standard</div>'     } else {         switch ($sess) {             case 'gallery' : echo '<div>gallery</div>';         }     }     ?> </body>

i have tried initiate refresh following on (external) ajax page;

$prior = $_session['view']; $_session['view'] = $_request['view'];  //allows filter set new value $post = $_session['view'] if($prior !== $post){header('location:'.$_server['php_self'].'?refresh=1');}

this did not work, because header sent (naturally), but thought !== approach step in right direction.

in second failed attempt, tried adding "refresh-page" code ajax script, reset filters values - defeating point.

$(document).ajaxstop(function(){     window.location.reload(); });

how can ajax (which included via external file) trigger if-statement re-check $_session value?
