I am attempting to understand how the product line entries in the shopping cart are filled in. I am assuming the bulk of this data comes together in the /includes/classes/shopping_cart.php file? I've tracked down most of the variables but I can't seem to get a grip on how the line item price is identified and the cart total. I'm not trying to change anything but simply trying to have a better understanding of the code. Any direction would be greatly appreciated. Maybe one day I'll be able to answer questions rather than always ask. Thanks. (ver 1.3.9h)
