Shop cart

[Zita]

Hi ! I need your help to change the item quantity in the cart.I thought to use a button “update” and change the total price only that item. I attach the source:
<?php if(!empty($_SESSION[“cart”]))
{
$total = 0;
foreach($_SESSION[“cart”] as $keys => $values)
{
?>

<?php echo $values["item_name"]; ?>
<?php echo $values["item_quantity"];?>
<?php echo number_format($values["product_price"],2); ?>
<?php echo number_format($values["item_quantity"] * $values["product_price"], 2); ?>

<?php
$total = $total + ($values[“item_quantity”]*$values[“product_price”]);
}
$totalI = 0;
foreach($_SESSION[“cart”] as $keys => $values)
{
$totalI = $totalI + ($values[“item_quantity”] );
}

        ?>

i don’t even see any “update button”, maybe you start with that?
