I am looking to integrate an ecommerce facility into an existing mature zope application. Anyone have any tips?

Thanks in advance,

Can you give a hint as to what you're looking for?

I was hoping for a solution for handling shopping carts, checkout processing, payment. A ready-made solution, so I dont have to think too much obout my requirements ;-) Also, something open enough that I can integrate it with the existing site that has a product catalog, but no way to purchase online.

You could take a look at CMFCommerce, which is fairly far along. Dunno how useful it would be if you don't care to use CMF. At the very least, you can take code from it.

Thanks. Ill take a look -- Toby Dickenson

Well, since you have to integrate with an existing system, you're going to have to modify any off-the-shelf component you find. I found the shopping cart to be trivial to do, so not worth trying to package as a product. on http://www.adirondackcraft.com we use a SESSION to hold a dict. The dict is keyed on item-number and the value is qty. Add to cart and remove from cart functions adjust the dict's values. When the customer clicks on "checkout", we pickle the dict's content into the URL and switch the browser to https. We had to put the dict into the url because some browsers dropped the session cookie when moving to https mode. The first https: url they land on is the "billing info" page. We have a database with an order table, and a line-items table. We create a new order record, populate the line items with the contents of the dict (encoded in the url when they first enter this page). Then we use a 'wizard like' interface to step them through billing info form, shipping info form and finally entering the credit card info. The credit card info doesn't get recorded in the database, instead we use the Cybercash Zope product to call out to (oh, guess it's verisign now) for real-time CC processing, then we record the AUTH details in the order record, navigate the user to a "here's a copy of your invoice page" and also email them a copy of their invoice. We spent far more time working on the layout of the forms than the backend processing. It's pretty easy, actually.

Also, something open enough that I can integrate it with the existing site that has a product catalog, but no way to purchase online. (http://www.geminidataloggers.com/products/selector)
