hi everyone...im having an issue with collecting the data using HTTP_REFERER
the problem is if i paste or type a referral url into the url bar it gives an error :-
Message: Undefined index: HTTP_REFERER
but if i click the link from another site it works perfect...
i understand that the error is because ts looking for a url of where the link came from, and if i pasted it, then there isnt a refferal url
but how would i write a code that will bypass this?
im thinking it would be a if/else command but i cant seem to get anything to work!
i need somethin that will say "if site url exists then collect data otherwise goto website normally"
any ideas please??
