i am trying to make a little referral sort of system for my site. so for that i settuped an extra parameter in the registeration url as :
www.domain.com/wp-login.php?action=register®ister_me=site_name
and one is adding ip address while registeration, at first i thought it would be a simple form in wp-login.php but i just found out its all based on filters etc.. very complicated stuff.
I did setuped two extra fields in the wp_user table. called 'reg_ip' and 'referral'
..
now i need to understand how to add these two things in wp-login.php so they will be inserted in teh database while registeration.
Help is really really appreciated :) cheers Ayaz
