i'm trying to do an online purchase for logging to a system. basically what i'm doing here is after they have registered and pay,then can only login to my website.
so i found lots of examples online on doing the buy button. however i cant find how it handles return url and and return variables. i would need the return variables so that i can verify payment is made and save it to my database.
is there anywhere i could refer?
basically i need to somehow crosscheck payment status for an item so that i can save it to db.
