[RESOLVED] Session Array Problem

kbc1

I am having a problem with a session array and hope someone can correct my problem.

When i post a page which allows the user to select the quantity of a product they wish to buy, I run this code:

	    

if (!empty($_POST['quantity'])) {
$_SESSION['cart'][$_POST['product']] = array('quantity' => $_POST['quantity'], 'productprice' => $_POST['productprice']); 
		$totalordervalue = CalculateMyOrder();
}

And the function which is called CalculateMyOrder is below:

function CalculateMyOrder () {

$quantitytotal = 0;
$pricetotal = 0;

foreach($_SESSION['cart'] as $product) {
   $quantitytotal += $product['quantity']; 
   $pricetotal += $product['quantity'] * $product['productprice']; 
   $newprice += $pricetotal;
}

$totalordercost = $newprice;

$_SESSION['S_TEMP_BASKET_QUANTITY'] = $quantitytotal;
$_SESSION['S_BASKET_TOTAL_QUANTITY'] = $quantitytotal;
$_SESSION['S_BASKET_TOTAL_PRICE'] = $totalordercost;

return $totalordercost;
}

The problem i am having is that when a user add a 2nd item to the cart, the function above is adding the new item price to the 1st item price plus the first item price again.

And when i add a 3rd item to the basket, it adds all items together plus, the 1st and 2nd items again and so on ..

I hope that is clear and i havent confused you.

How can i prevent the $_SESSION['S_BASKET_TOTAL_PRICE'] from being updated incorrectly?

Thanks in advance.

Change:

$pricetotal += $product['quantity'] * $product['productprice'];

To:

$pricetotal = $product['quantity'] * $product['productprice'];

And see of that helps.
