Undefined index error after logout

Question

I am getting undefined index error after logging out from my web page. When i stay loged in it is all good, but when there is no1 loged in it shows error. Session active i checked. Undefined index: User from

if($_SESSION['Auth']['User']['role'] == 'admin') {
    echo 'some html code';
}

only when no user is loged in! Any ideas? Thanks in advance.

you have destroy the session when logout. so `$_SESSION['Auth']['User']['role']` on login page. — Satish Sharma, May 26 '14 at 06:03
Why are you referring to `$_SESSION` in a CakePHP application? — AD7six, May 26 '14 at 08:09

If no one is logged in, then $_SESSION['Auth']['User']['role'] does not exist, so you are getting the undefined index error. Try this instead:

if (isset($_SESSION['Auth']['User']['role']) 
    && $_SESSION['Auth']['User']['role'] == 'admin') { 
    // admin is logged in
}

you have destroy the session when logout. so $_SESSION['Auth']['User']['role'] on login page.

But you can avoid the error which you are getting by checking isset

if(isset($_SESSION['Auth']['User']['role']) && $_SESSION['Auth']['User']['role'] == 'admin') {
    echo 'some html code';
}

Try this

if(isset($_SESSION['Auth']['User']['role']))
{ 
        $_SESSION['Auth']['User']['role'] == 'admin') 
        {
            echo 'some html code';
        }
}
