Hi
I'm built a fairly basic add to shortlist function on my website similar to a session based add to cart.
Here is the code for my add to shortlist button.
<a href = "http://www.website.com/cart.php?action=add&id=' . $id . '" <b>Add to Shortlist<b> </a>
Here is the code for my cart page.
`<?php
// Start the session
session_start();
?>

$id=1;

$action='empty';
switch($action)
{
case 'add':
if (isset($_SESSION['cart'][$id]))
$_SESSION['cart'][$id]++;
else
$_SESSION['cart'][$id]=1;
break;
case 'remove':
if (isset($_SESSION['cart'][$id]))
{
$_SESSION['cart'][$id]--;
if ($_SESSION['cart'][$id]==0)
unset($_SESSION['cart'][$id]);
}
break;
case 'empty':
unset($_SESSION['cart']);
break;
}
/*Display cart*/
if (isset($_SESSION['cart']))
{
foreach($_SESSION['cart'] as $id)
{
$result = mysql_query('SELECT * FROM test WHERE id= '. $id .' ');
$row = mysql_fetch_array($result);
}
if($result === FALSE) {
die(mysql_error());
}
while($row = mysql_fetch_array($result))
{
echo $row['name'];
}
}
else
echo 'Cart is empty';
?>
</div></div>
<?php include ("footer.php"); ?>
</body>
</html>`
The cart is empty message is working fine but when I add anything to the cart the results are blank. I'm sure its something simple but I can't see it.
Thanks
