I'm not sure what the other progammer did, but I only have this checkout_paypalipn.php file.
Had searched the net and this module seems to be the one that's using this file. (PayPal IPN v0.981 for Milestone 2)
I wish to modify the way this script works by updating the products_ordered DB only when the order status has been set to Delivered.
Any off hand solutions out there?
