* Class ShoppingCartModule - mini shopping cart display
|
|
*@author Erik Winn <erikwinnmail@yahoo.com>
|
|
*
|
|
* This module provides the mini cart view for items in the shopping cart.
|
|
* It is created by default for any user that signs in. An account has one
|
|
* shopping cart, when checkout occurs the items are removed from the
|
|
* cart when the order is created.
|
|
*
|
|
* The mini view is a small box containing a hyperlinked list of the items
|
|
* in the cart, clicking on an item redirects the user to the product page, clicking
|
|
* on the title header ("Shopping Cart") redirects the user to a full cart view page.
|
|
*
|
|
*@todo
|
|
* - add total price (incl. shipping) estimates
