form with multiple data

[frezno]

in a database products with various attributes are stored, eg
jersey in sizes Small, Medium, Large XLarge
wallet in Black, Blue, Red, Yellow
etc.

when displaying a product those attributes will be shown + a field for entering the desired quantity for purchasing it:

Jersey

Size     | Qty
Small    | [0]
Medium   | [0]
Large    | [0]
XLarge   | [0]

or

Wallet
 
Color    | Qty
Black    | [0]
Blue     | [0]
Red      | [0]
Yellow   | [0]

as said, both attributes (eg size or color) and the quantity are produced dynamically from the database.
Now if a user buys 2 Jerseys in Medium, ie types a 2 into the quantity input field of Medium and presses 'submit',
how do i know that the quantity of 2 refers to the medium jersey?

<input name="items[Jersey][Small]">
<input name="items[Jersey][Medium]">

<input name="items[Wallet][Black]">
<input name="items[Wallet][Blue]">

print_r($_POST['items']); 

However, if you give each item its own itemid, this wouldn't be neccesary at all. A blue wallet would have a different itemid than a black wallet. Then you can just use a single dimensional array like

<input name="items[123]">
<input name="items[124]">

<input name="items[555]">
<input name="items[556]">
