I'm currently using the PayPal IPN payment module, although I'm not entirely sure if this issue is related to it or not. The problem seems to be centred around the checkout_confirmation page.
If a customer reaches that page and then decides to go back and change their shipping address, billing address, or shipping method, the order that was written into the database does not reflect the changes they make, nor is a new order generated. What the customer sees on the screen changes, and the correct data is sent to Paypal when they pay (new order total, shipping method & rate, etc.), however the order I see in admin (and thus what they see in their order history and order confirmation email) shows the order as it was before they made any changes. In addition, even though payment is successfully completed, the order status displays as "Pending" "PayPal IPN Verified [payment status: Completed]" instead of "Completed" "PayPal IPN Verified [payment status: Completed]". Interestingly, when a customer makes any change to items in the shopping cart, a new order *is* generated in the database when they hit the checkout_confirmation page again.
What can I do to allow these other changes to be "recorded" in oscommerce?
(thanks in advance for any advice!)
