search multiple fields using multiple form elements

bickyz · March 24, 2013

thank you very much barand, I have set the session at the top of the page, no errors now.

how do i now tag the session from index page to the sort-by drop down list in results page so that selecting items from the drop down will use the session.

<?php
ini_set('display_errors',1);
error_reporting(E_ALL);
?>
<?php
include 'db.inc.php';
?>
<?php
session_start();
$_SESSION['duration']='duration';
$_SESSION['datepicker']='datepicker';
$_SESSION['transport']='transport';
$_SESSION['activity']='activity';
?>
