Cart³

Cart3 requires the cart3 Centre Option in order to work
Note: You do not need the new_cart centre option, but new_order_proccess is required.

Overview

Cart3 is the new Core dna eCommerce cart. It was created to combat the problems of the other carts becoming complex and hard to use. It no longer stores it's data in the session, using the database instead. This allows us to retain guest carts and pull out old carts at any time.

On every page load, Cart3 is assigned - so no matter where you are you will have access to the Cart3 object. It's called $cart3.

Every load of Cart3 will also load all the current Discounts and Vouchers. We no longer insert this data into the checkout screen in one go - but allow this information to be passed at anytime, anywhere.

Every Cart3 is loaded by what is called the Cart Key. This is a salt of the centre_id, session_id and user_id. This is unique to every Cart3 instance.
