Update Function Shopping_Cart

[wizzard81]

Hello,

I need some help with an update function for my shopping cart. If there are 2 or more items in the basket like

1) INTEL CPU 2.4 Quantity:1
2) MB AsuS Quanity1

If the user changed the quantity from one or 2 products and press on the recalculate button everything has to be updated.

My problem is how do i send all the productids and quantity's to a function so the function knows what has to be updated. Can someone gives me an example?

Regards
Kris

anyone?

I send it via javascript, like this...

function UpdateQty(item) {
	itemId = item.name;
	newQty = item.options[item.selectedIndex].text;
	document.location.href = 'cart.php?action=update_item&id='+itemId+'&qty='+newQty;
}

Which is then sent to the php function

function UpdateItem($itemId, $qty)
{ 
	// Updates the quantity of an item in the users cart.
	// If the qutnaity is zero, then RemoveItem will be
	// called instead
	global $dbServer, $dbUser, $dbPass, $dbName; 
	// Get a connection to the database
	$cxn = @ConnectToDb($dbServer, $dbUser, $dbPass, $dbName);

if ($qty == 0) {
	// Remove the item from the users cart
	RemoveItem($itemId);
} else {
	mysql_query("update cart set qty = $qty where cookieId = '" . GetCartId() . "' and itemId = $itemId");
} 
} 

You'll have to mess about with that, else it will do absolutely nothing.

It's not exactly what i'm looking for.

does that function change quantity? because what i did when i needed to change quanity in my script is select the number subtract or add how many... then replace
