registration php file.
I have been trying to get this sign up php to work. I'm close, I guess. But there's a problem. The result is always a button that redirects to the homepage(You'll know what I'm talkin about when you read the code.) If you could find the problem please tell me.

You're missing an = on the line
if($status="NOTOK"){
It will assign the "NOTOK" to the $status and be boolean true.
