[RESOLVED] array search

[benracer]

how is this wrong?

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

for...

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

Thanks

array_search looks in the values of the array, not the keys, for a match. If $SESSION['cart'][$id] had a value of say "blue", then your unset call would be:
unset($SESSION['cart']['blue'])
instead of your expected result. Since you know the ID, and the key you're trying to unset is the ID, just use:

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