I have a test script..
What i'm trying to achieve is once the user has clicked on link1 the value
of item must equal x and if the user clicks on link2 the value of items must
stay equal to x while setting action equal to y ..
<?php
session_start();
echo 'Welcome to testpg';
$_SESSION['time'] = time();
if (isset($_GET['item'])){
$_SESSION['item'] = $_GET['item'];
echo $_SESSION['item'];
}
if (isset($_GET['action'])){
$_SESSION['action'] = $_GET['action'];
echo $_SESSION['action'];
}
?>
<html><br /><a href="test.php?item=x&<?php echo strip_tags(SID);
?>">link1</a></html>
<html><br /><a href="test.php?action=y&<?php echo strip_tags(SID);
?>">link2</a></html>
thanks
