[SOLVED] multiple items in array

[wmguk]

Hey,

 

I'm using a cart system and I'm changing the code quite a lot to handle the item and the price...

 

I click a link

<td><a href=cart.php?action=add&id=$name&cost=$cost>Add</a></td>

 

which goes to:

if ($action=="add") {

	if ($cart) {
		$cart .= ','.$id.":".$cost;
	} else {
		$cart = $id;
	}

 

and then when i try to see whats in the cart i use:

 

<?
$cart = $_SESSION['cart'];
if ($cart) {
	$items = explode(',',$cart);
	$contents = array();
	foreach ($items as $item) {
		$contents[$item] = (isset($contents[$item])) ? $contents[$item] + 1 : 1;

	echo $item."<br>";
	}}
?>

 

but i dont get to see the cost, is there a way of using more than one variable in an array?

[wmguk]

ah ok,

 

I used list...

 

list($name, $cost) = explode(":", $item);
echo $name." - ".$cost."<br>";

is there anyway to add the $cost together to create a total?

[wmguk]

nevermind....

 

$total += $cost ;

 

I'm going home now
