[RESOLVED] Using While Loops on Session Arrays - please help!

[designrandom]

Can I use a While Loop on a session array?

What I mean is, can I do this, but for an array result instead of a mysql query result?

while ($row = mysql_fetch_array ($result)) {
echo 'output goes here';
}

How would I do this for a session array that looks like this? I need to get the $sessID for each instance of the shopping cart session.

$_SESSION['cart'][$sessID] = array ('quantity' => 1, 'price' => $prodPrice, 'prodName' => $prodName, 'handle' => $handle);

There is a good chance that I'm actually making this very difficult for myself. If any one has a better idea of how to do the following, I would love to hear it! Thanks...

I am building a php/mysql shopping cart for a cricket website. When the website user adds a cricket bat to the shopping cart they must select some options:

Bat size, Handle size, Bat Edges, Bat Weight, Etc...

There are between 6 and 10 options depending on the chosen cricket bat.

I add the details to the shopping cart session like this:

$sessID = uniqid();

$prodID = (int) $_POST['prodID'];
$prodName = $_POST['prodName'];
$prodPrice = $_POST['prodPrice'];
$size = $_POST['size'];
$handle = $_POST['handle'];
$weight = $_POST['weight'];
$edges = $_POST['edges'];

$_SESSION['cart'][$sessID] = array ('quantity' => 1, 'price' => $prodPrice, 'prodName' => $prodName, 'handle' => $handle);

On the viewcart.php page I intend on outputting the price and product name from the shopping cart arrays.

The problem is, I don't know how to set a while loop for all the instances of $sessID?

Any thoughts on this would be greatly appreciated.

Thanks

Not sure if this is what you want, but it might be something like:

foreach($_SESSION['cart'] as $id => $data)
{
   echo "<tr><td>$id</td><td>".$data['quantity']."</td><td>".$data['price']>."</td>etc....</tr>";
}

NogDog,

I can't tell you how much I appreciate this!! Thanks so much. It seems to work perfectly.

Thanks again.

NogDog,

I forgot to ask you about adding the totals for the shopping cart!!

This obviously outputs the same price a few times, rather than multiplying them together:

foreach($_SESSION['cart'] as $id => $data)
		{
			$subtotal = $data['quantity'] * $data['price'];
			$total += $subtotal;

	echo $subtotal;
	}

Any ideas?

Thanks again

Erm, sorry - I've actually sussed the problem!!

This does it, for anyone that cares:

foreach($_SESSION['cart'] as $id => $data)
		{
			$subtotal = $data['quantity'] * $data['price'];
			$total += $subtotal;

	}
	echo $total;
