If you omit any of them the data will not be - saved to the cart. The fifth index (options) is optional. It is intended - to be used in cases where your product has options associated with it. - Use an array for options, as shown above. - -The five reserved indexes are: - -- **id** - Each product in your store must have a unique identifier. - Typically this will be an "sku" or other such identifier. -- **qty** - The quantity being purchased. -- **price** - The price of the item. -- **name** - The name of the item. -- **options** - Any additional attributes that are needed to identify - the product. These must be passed via an array. - -In addition to the five indexes above, there are two reserved words: -rowid and subtotal. These are used internally by the Cart class, so -please do NOT use those words as index names when inserting data into -the cart. - -Your array may contain additional data.

The reason a unique ID is created -is so that identical products with different options can be managed -by the cart. - -For example, let's say someone buys two identical t-shirts (same product -ID), but in different sizes. 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.
