note 83714 rejected from ref.session by mgf

Note Submitter: dchouser at gmail dot com ---- question: Lets say I have a MYSQL table called "users". I've created a registration page that inputs their name, password, email, etcl. I want to have a login form on my index. If somebody is already logged in, I don't want the form to show, I want it to say "Logged in as - "userName"". I figured I could use sessions. Like: session_start(); if (!isset($_SESSION['SESS_MEMBER_ID'])) { show "logged in as" } else { show form} Is this right? I cant seem to get it to work.
