Where is $_SESSION['cart'] set?

Hello

I would like to know where $_SESSION['cart'] is set?

In v1.5.6 it's set here:

Thanks DrByte, what about v1.5.1?

I'm really hitting hard my head to figure out how I could do.

Each product_id of my catalog comes in different "versions". Those versions are identified by a serial number. I want customer to choose from a dropdown the serial number they want.

I could do this with attributes, BUT I store serial numbers in a separate database, on the same server, so I need to pass to shopping cart, and to classes/order.php and classes/shopping_cart.php this variable.

I really don't know how to make it work. I see in shopping cart page that it gets a POST "serialNumber" as it should, but I don't understand how to store that with the product.

It should work just like TEXT attribute.

But I don't understand.

Could you please give me an hint so I can maybe find the way?

Thank you

Wasn't this already asked here: https://www.zen-cart.com/showthread....79#post1367479

What new information has been provided?

It was a different approach using $_SESSION because you suggestion to go through extra_cart_actions was no help.
