Hello everyone, I have 2 of my php pages. I am starting a session in my first page and setting the setting variables but whenever I am trying to access that variable in the 2nd page it doesn't show an error neither it pops out my desired result. In short its not showing the session value, its null. In my 2nd page(cms.php) at line 48 you can see that my variable is called but no output is there please help

It looks like this logic might be a little askew in cms.php:

$something = isset($_POST['user_name'])?$_POST['user_name']:'';
if($something) {
    $_SESSION['user_name']=$something;
}

As you are attempting to pull it out of the session in cms.php after the login, it should be

$something = isset($_SESSION['user_name']) ? $_SESSION['user_name'] : null;
if ($something === null) {
    echo '<p>Not logged in.</p>';
    //exit();
}

(Just for reference, this is a continuation )
