Hi, If you use namecheap.com you'll know you can credit your account by simply following through the appropriate linked namecheap and paypal pages, and at the end of the transaction your account will now have more money. I'm running a pay-per-click service which is run on points. I desperately need help with a paypal merchant standard check out I've signed up to. Basically, how do I allow it so that when the user logs in on my site, clicks "Buy points" their username is then taken to paypal so the transaction bar (like on namecheap) will show something like: Then, after the transaction, how will I retreive the username so I can then credit their account using PHP? Help is greatly appreciated. Thanks, Lee.
