making FORM dissapear when successful login

JHollis <jhollis@xxxxxxxxx> · Tue, 04 Jan 2005 21:05:25 -0500

I had this code working the way i wanted it to (as far as correct 
username and password allowing successful login)...but what i want to 
happen now is when a user successfully logs it it will make the login 
form disappear and just say successfully logged in or welcome user and a 
link below it so they can log off and make the form re-appear.  Below is 
the code that i have where i tried to get it to disappear on successful 
login, but it stays disappeared all the time.  Can someone please point 
out what im doing wrong.  I have tried everything i can think of...and 
nothing works.  Im a PHP newbie...so im sure some of you might get a 
laugh out of this...if it is real easy.
