Im trying to make a referral script that will log how many individual visitors a person has referred with their link. For instance: they sign up for the referral program and get their own link:
If someone goes to this link:
Then it would check the person's IP (to see if they have already been counted in the referral system before), then if they haven't been counted... it would log one new click for the user: Xibe.
How can I make something like this?
