I have a client running on a D6 site that is a combination of flash animation and Drupal content. They decided at the start that they didn't want to go the e-commerce route per se, they wanted product pages that fed an online order form that gets e-mailed, despite my advising them that they would probably want to do otherwise later, and that they were not positioning themselves to ease the transition. The product page has a 'cast' of flash animated product thumbnails, and the current product as a large flash animation. A 'baseball' card of Drupal content provides the product info, and a quantity field, which when submitted provides 'add-to-cart' functionality. The client now wants e-commerce, in terms of an order, payment and shipping. They want to retain the product page and the order form as the 'cart.' Those two existing functions are done via a custom module, so I'm thinking that with the 'add-to-cart' functionality I might be able to just change the form name to the one Ubercart uses, if necessary, and replace the content of the standard form. What I'm wondering about is using the online order form as the cart. It looks like image cart detail, with more columns and some ship-to/bill-to data. I can remove the ship-to/bill-to fields and use UC's at order time, but in using this form as the cart, has anyone any tips/pitfalls? Loosely, not having dived into it yet, I'm thinking of 'simply' making use of the UC cart callbacks and ensuring I pass the correct data along...but it's probably not that straight-forward. Jeff
