Using oscommerce as a cart for other applications

[ajosey]

I want to use oscommerce as a cart/payment engine for other applications we are running to replace

our current use of Paypal basic (in oscommerce we will use the Paypal Direct/Express module).

 

So far i have managed to put some simple php together that allows us to place an add to cart button

in other applications, that uses our model number rather than the oscommerce product id (which might change) and have the appropriate product arrive in the cart when clicked.

 

What i'd like to do is to be able to post some additional text into the query and have that end up

as part of the order number (i.e. part of the specific order data so it can appear on invoices etc), for example a reference id that can link back to my other application, i.e. to buy an event registration with the attendee reference name and number.

 

Has anyone done anything like that (without using a cookie)?

 

The other feature I'd like is a return url , so that after a purchase has been

completed in osc, if the URL was set, the customer could be redirected back to our other application.

 

Any pointers or suggestions would be much appreciated

thanks

Andrew
