hi,

$_SESSION["cart"][] = $id;

hi,
the items are displayed in a shopping cart and i would like to have a function that removes them. currently the item id is stored in an array and i post it to this...

$id=$POST['id'];
unset($SESSION['cart'][$id]);

but now i have changed it so i can add a quantity feature. so is it possible to add the index number to the value of an hidden field and post it to this...

$id=$POST['id'];
unset($SESSION['cart'][$id]);

Sure here is an example:

<?php
$cart = array();
$cart['cart']['id']['shampoo']['quantity'] = 1;
print_r($cart);
?>

this will produce:

Array ( [cart] => Array ( [id] => Array ( [shampoo] => Array ( [quantity] => 1 ) ) ) )

ok...

i have items stored in an array in a session.

if ( !isset( $_SESSION["cart"] ) ) { 
    $_SESSION["cart"] = array(); 
} 

$id = $_POST["id"]; 
$_SESSION["cart"][] = $id; 

so when the session is looped is it possible to put the [xnumber] into this..

<form id="id" name="id" method="post" action="/cart/remove_item.php">
<input type="image" src="/images/x2.gif" alt="Remove This Item">
<input name="id" type="hidden" id="id" value="<?php echo $xnumber ; ?>" />
</form>

which is sent to this...

$id=$POST['xnumber'];
unset($SESSION['cart'][$id]);

What you want to do is find the key of the array item that holds $id, so something like this should work:

unset($_SESSION['cart'][array_search($id,$_SESSION['cart'])]);
