Array Question

[kbc1]

Hi all

I store details of my shopping basket into an array when the user types a quantity and colour required of a product and then hits the submit button. My array is as follows:

 $_SESSION['cart'][$productid] 	= array('quantity' => $_POST['quantity'], 'productprice' => $productprice, 'productsize' 	=> $productsize,'productcolour'	=> $_POST['selectedcolour']);

And then I list the items form the array in my basket as such:

foreach ($_SESSION['cart'] as $k => $v) {
// do stuff here
}

However I have just come across a problem in that, I need to be able to allow the user to go back to the product page and select a different colour/quantity combination and this be ADDED to the basket rather than updating the exisiting record in the array. I think this is because I am using the [$productid] as the key of the array.

How would I get round this without having to re-code much of my work that loops through the array etc?

Thanks for reading.

Hey

I can only think of 2 ways, not sure either will be much help... nest an array of attibutes so you can have multiple quantities etc for that product id but i'm guessing this would be a lot of work

$_SESSION['cart'][$productid] = array(
0=array('quantity' => $_POST['quantity'], 
'productprice' => $productprice, 
'productsize'     => $productsize,
'productcolour'    => $_POST['selectedcolour']);

The other way is to make sure each colour product maps to a different product id. This would probably be the most realist solution as when you order from a supplier, they will have a different code for the same item in different colours. This might also help you track stock better as you'll clearly know how many of each colour you have in stock

Hope this helps
