I need help with sessions... How do I get it so when you are not logged in, It says login or register in the corner but if you are it says who you are logged in as? I'm learning PHP atm, You can see what I mean by going to http://www.gergy.info

quick version...

 

<?php if(!$_SESSION['loggedinornot']) { echo "Register | Login"; } else { echo "Welcome back!!"; } ?>

 

changing loggedinornot to match you session id..

Heres a basic example

When i user logs in, you can set a session like this

<?php
session_start();
//connect to database and check login details
//get UserID eg $row['UserName']
//set to session
$_SESSION['UserName'] = $row['UserName'];
?>

 

Now on other pages if that session is set you can check it like this

<?php
session_start();
if(!empty($_SESSION['UserName']))
{
echo "Welcome Guest <a href=\"login.php\">Login</a>";
}else{
echo "Welcome ".$_SESSION['UserName'];
}
?>
