What Gumbo meant with his "use array instead" comment is the following:

In your HTML-form use this:

and $_POST['quantity'] will then be an array of all containing all of your quantities.

If you need to supply an id you can also do this:

$_POST['quantity][0] will then hold the corresponding quantity.
