Simple Session Help

[herghost]

Hi all,

 

I am trying to display a link if a user is logged in or  not etc, here is my code:

<div id="nav">
                  <a href="">My Account</a>  
<?php
if ($_SESSION['logged'] !="1")
{
?> 
| <a href="scripts/login.php" onclick="return GB_showCenter('Login', this.href, 200, 400)">Login</a>|
                  <a href="scripts/reg.php" onclick="return GB_showCenter('Register', this.href, 280,550)">Register</a>
                  <?php   

}
else {
}
?>| 
                  <a href="">Contact</a>| 
                  

<a href="scripts/logout.php" onclick="return GB_showCenter('Logout', this.href, 200, 400)">Logout</a>


                     
              </div>

 

Basically this all works if the user is logged in, the reg and login links are not shown, however if no user is logged in then I get an error saying the session is an undefined index.

 

I am guessing that i have to say 'only if the user is logged in then check this', iI think i do this with isset but not sure on how I include the ! clause in a isset statement.

 

Any help would be greatly appreciated!

 

Thanks

Not to worry:

 

<div id="nav">
                  
<?php
if(isset($_SESSION['logged']))
{
	?>
        <a href="scripts/logout.php" onclick="return GB_showCenter('Logout', this.href, 200, 400)">Logout</a>

	|<a href="">My Account</a> <?php 
}
else
{

?> 
| <a href="scripts/login.php" onclick="return GB_showCenter('Login', this.href, 200, 400)">Login</a>|
  <a href="scripts/reg.php" onclick="return GB_showCenter('Register', this.href, 280,550)">Register</a>
<?php   
}
?>| 
                  <a href="">Contact</a> 
                  



                     
              </div>
