First, you'll need to add session_start()
at the top of any page that you wish to use SESSION
variables on.
Also, you should check to make sure the variable is set first before using it:
if(isset($_SESSION['SESS_fname'])){
echo $_SESSION['SESS_fname'];
}
Or, simply:
echo (isset($_SESSION['SESS_fname']) ? $_SESSION['SESS_fname'] : "Visitor");
