PHP Output Variable Not Appearing

Question

I am using an open source login repository from Github (https://github.com/panique/php-login-minimal) to create a login system for my website. The login process seems to be successful and the new user registrations are populating to my MySQL database, but when I try to echo session variables like the username it is just coming up blank.

Here's a sample code that doesn't show up:

<p>Hey, <?php echo $_SESSION['user_name']; ?>. You are logged in.</p>

and I have also tried this:

<p>Hey, <?php echo("{$_SESSION['user_name']}"); ?>. You are logged in.</p>

but to no avail. You can also see how this problem works on the live site at http://www.geneticgolf.com/views/logged_in.php .

Any help on what I'm doing wrong would be appreciated.

Are you sure authentication is happening? That's when the `$_SESSION` var is set. have you tried `print_r($_SESSION);` to see if it has ANY data? — Andrew Coder, Jan 21 '16 at 23:43
That class seems like an overly odd way to handle authentication... but thats just an opinion. — Andrew Coder, Jan 21 '16 at 23:48

Ensure that at the top of the same page that has this code:

<p>Hey, <?php echo $_SESSION['user_name']; ?>. You are logged in.</p>

that you have (as the first instruction):

<?php
    session_start();

If you have that correct, then try this:

<?php
    session_start();
    echo '<pre>'
    echo $_SESSION;
    echo '</pre>'
    die();

At the least, that will tell you what is in your $_SESSION variable.
