Using the existing static (i.e., not database generated) web pages (Note that a complete 'shopping cart' program is neither needed nor desired) 3.? Using PHP5 (not Javascript, hidden HTML form statements, URL parameters, etc.) to transfer the buyer's selected product information to a checkout page (Note that the products' price? must be? changed as specified? when the? shopper selects various? product options) 4.? Make the checkout/submit page which will properly perform the complete [login to view URL] interaction as recommended by [login to view URL] 5. Providing me with step-by-step instructions that I can follow when additional static product pages are to be added and connected to the [login to view URL] account ? At this time - to keep the cost minimized - I am planning to forego the "remove product" and similar shopping cart functions.? The shopper sequence is expected to be: ? * The shopper peruses various products and decides to purchase one. ? * The shopper selects the associated product options (e.g., size, color, etc.) desired.? Note that these options employ a simple XHTML form, and that? OPTION? SELECTIONS? ALTER THE PRICE? of the product being purchased. ? * The shopper, upon clicking a buy now button, is directed to a checkout page whereon their credit card and related information is received, and whereon their product selections are echoed.? It is this checkout page that must "talk to" [login to view URL] in the proper fashion. ? * The shopper, upon successfully completing the checkout information, is directed to a 'thank you' page. ? * The shopper, upon un-successfully completing the checkout information, is directed to an appropriate (i.e., different) page. ## Deliverables The associated product? page layouts (the XHTML, CSS, and graphics), and the 'Thank You for? Your Order'? page layout (the XHTML, CSS, and graphics)? are already designed.
