MySQLi Log In User - How to detect if a user is logged in and how to hide certain content based on that (not auth levels)

I need to display either a "Sign in" button or a "Log Off" button depending on whether or not a user is logged in or not.
Can this be done considering I've built the whole thing in MySQLi?

Thank you

When you create the login behavior, the First setting on the general tab is the login name.

On login success a session variable is created using the login name as:
WA_AUTH_<login name>

so for example if you name the login "MyLogin", the session will be created as
WA_AUTH_MyLogin

you can create an if statement to check for that session variable and show logged in or not logged:

<?php
@session_start();
if(isset($_SESSION['WA_AUTH_MyLogin'])) { 
?>
Logged In
<?php } else { ?>
Not Logged In
<?php } ?>

Receiving a Parse error with that code:

Parse error: syntax error, unexpected 'if' (T_IF) in C:\inetpub\wwwroot\smt\smtadmin\navbar.php on line 27

Line 27 is:
if(isset($_SESSION['WA_AUTH_USER'])) {

Thank you.

sorry, forgot the semi colon at the end of the session_start line.

that line should be:
@session_start();

Thank you. That's fixed it.

you're welcome.
