Redirect to member profile after login

[basketmen]

1. i need user redirect to member profile after they login, so not redirect to forumhome

I am find this and try it www.vbulletin.com/forum/showthread.php?t=184417&highlight=login+redirect






2. Thread above is almost right to add the code but i dont find the right REDIRECTION URL format for userid

This is the code from thread above that i need to add
<input type="hidden" name="url" value="REDIRECTION URL HERE" />




This is REDIRECTION URL that i tried

<input type="hidden" name="url" value="profile.php?id=$bbuserinfo[userid]" />

but the result is this

http://www.domain.com/profile.php?id=0





I tried this too





<input type="hidden" name="url" value="profile.php?id=$userid" />

but the result is this

http://www.domain.com/profile.php?id=








Those url redirect format is not works, what is the right userid format that i need to use? or username format is OK too


Really need help for this
