How to get items in opencart cart?

Question

opencart

Hello everyone , I'm new to
opencart, so I ran into such a problem (I looked at the PS documentation and did not find an answer to my question there)
each product was assigned a unique number (it will be random from letters and numbers). And even if you bought 2 identical goods, then "bolt 1" will have one number, and "bolt 2" will have another.
The problem is that I can not find the controller and the method that is responsible for the items in the cart.

Answer 1

Most likely you need this file: system/library/cart/cart.php

Answer 2

In opencart, everything is simple,
the controller that is responsible for the cart is called "Cart"

Only the product, when added, as far as I remember, is stored in the session.
