Here is what I am trying to do: I'll try to describe it as clearly as possible I have a main website - www.maindomain.com On that website, there is a signup page & link. The URL is encoded with a basic referral ID #.... something like this. https://www.signupserver.com/?referralid=12345 ~~~~~~~~ What I want to be able to do is this. Say someone else has a separate domain name.... say www.anotherdomain.com That domain is set to forward to maindomain.com using a masked forward. If someone visits www.maindomain.com via. the forward-ing domain, and goes to the sign up page, the signup URL would be encoded with a different number, based on the specific forwarded domain that the person used. ~~~~~~~~~ So something like: Singup link: https://www.signup.com/?referral=$variable if forwarded domain = aaa.com then $variable = (value set manually by me) if forwarded domain = different domain then $variable = different value. so forth and so forth. ~~~~~~~~ Any help would be appreciated. I am in the process of learning basic PHP & JS, so if it would be as simple as using certain functions to obtain & read the redirecting domain, I could probably figure it out on my own if I had some pointers to work with.
Perhaps have the other domain redirect to a URL like www.mydomain.com/?idtagnumber=12345 then do something like: https://www.signup.com/?referralid=$variable ~~~~~~~~~~ when someone visits from forwarded domain setcookie (value is based on idtagnumber) if idtagnumber = 12345 then $variable = 12345 or if cookie = 12345 then $variabl = 12345 otherwise $variable = default ~~~~~~~~~~~~~~~ How complicated would this be to set up? Thanks
