Is there a guide on how to create a log in + sign up, referral system for a website that sells stuff? (referral gets a % of who he refers)
Can you be a tad more specific, I think you're probably going to be looking for an already coded solution for what that's sounding like. Otherwise its a matter of keeping track of your members ID (or making a unique refferal ID for them when they sign up), and then when new users sign up to paste that refferal ID into the box, you could just simply have it look up in the database if that user exists, and to add whatever count to their field.
I hope you are trying to create an affiliate program. There scripts available with this facility. But I am not sure whether there some free ones. You will have to search for this. Just to have a demo you can try Jrox and idev affiliate programs
Yea, kind of. For example if someone refers his friend and his friend buys something, the referrer would get 0.20% of what his referrer spent.. Where can I find this script?
