I updated the confirm.php file to update the orderoptions table and FTP'd it to site.
I then thought I'd test it so I selected a course and clicked on the Buy with PayPal button (the only one available). When I got to PayPal's site I opted not to log-in and bought with a credit card. This should have taken me back to the confirm.php page on the site shouldn't it? But it didn't, it took me to the pp_confirm.php page which already had that "update orderoptions table" code.
I'm confused now. Am I misunderstanding this?
