RE: [CFCDev] Help with OO Model for Shopping Cart

Title: Message

I’d personally model the coupon as a separate object, and maybe extending a default discount object. The discount object is always calculated on checkout and this enables you to do multiple discount types using inheritance. Not only coupons, but also customer specific discounts.

This works well and I have no real problem with it.   However, I now need to implement a pretty robust coupon/discount functionality into the app, and I can't seem to figure out how to do it. I need to allow for four types of coupons:   (1) Whole order coupon (NN% off entire order) (2) Single item coupon (NN% off this item) (3) Multiple item coupon (buy one (or two), get the 2nd (or third) NN% off) (4) Free item coupon (buy this item, get a free toaster)   I think I can figure out how to model a single coupon type, but as I'm an OOP newb, figuring out how to model and implement the whole range has got my head spinning.   Can anyone point me in the right direction?   Jim McMullen Devlab, Inc. ---------------------------------------------------------- You are subscribed to cfcdev.
