Question

I was trying to apply this little code on my codeigniter page to see if the login is going to replace the logout if a user logged in, and vice versa. I tested it on welcome page that comes with codeigniter framework, but nothing happen. The only thin I see is login link. I tried to use tank auth as login library to make things easy, but whenever I login to the welcome page, again the login link shows up again, which is none sense.

here is the code I used to replace login/logout

<?php if(isset($_SESSION['username']) && $_SESSION['username']!="")

{
echo("<a href='logout.php'>Logout</a> ");

echo($_SESSION['username']);
``// displays username
}
else
{
echo("<a href='login.php'>Login</a> ");
}
?>

Perhaps your login script is not setting the $_SESSION properly. Use Firebug to see if you have an active session. I’d also use a method to check whether users are logged in:

Your login class:

public function is_logged_in()
{
   if($this->session->userdata('username'))
   {
       return true;
   }
}

Your view:

if($this->login->is_logged_in())
{
   echo anchor('logout','Logout');
}
else
{
   echo anchor('login','Login');
}
