The product ID (and other attributes) will -be identical for both sizes because it's the same shirt. The only -difference will be the size. The cart must therefore have a means of -identifying this difference so that the two sizes of shirts can be -managed independently. It does so by creating a unique "row ID" based on -the product ID and any options associated with it. - -In nearly all cases, updating the cart will be something the user does -via the "view cart" page, so as a developer, it is unlikely that you -will ever have to concern yourself with the "row ID", other than making -sure your "view cart" page contains this information in a hidden form -field, and making sure it gets passed to the ``update()`` method when -the update form is submitted.
