Cart Order Tracking and Authorize.net Full/Partial Refunds

Premise: I need a cart created using an existing source for a website. It has database backend mysql. the site is coded in PHP. I already have the [login to view URL] forms worked out for data entry but I don't actually have the cart done yet (partially done). the cart needs to 1) send a confirmation after order to customer with order details, 2) write that information to a text file and also email it to me. I wish to also have an admin area that 1) View shopping cart information 2) section for admin refunds, partial refunds, full refunds 3) Add payment gateway [login to view URL] (already have the scripts kinda worked out see order dir) 4) Cart progress information (I can change the customers order: delete items, add items, mark certain items as backorder/out of stock current problems with the cart that I have coded is that it won't add the actual product to the table and won't increment the price when quantity goes up but that's it and then mysql needs to be integrated into it so it'll actually pull the product info and then the above steps of course ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
