Getting value from session PHP

Question

I am not sure why the variable username is not being returned in the session. When the user logs in, I start the session:

$username = trim($_POST['username']);
if(!isset($_SESSION)){ session_start(); }
$_SESSION[$this->GetLoginSessionVar()] = $username;

On the user's welcome page, when I run the echo command, I see the proper variable being returned. But I'm not sure why the return statement isn't working. I have the following in my PHP file:

function UserName()
{

    return  isset($_SESSION['name_of_user']) ? $_SESSION['name_of_user'] : "Unknown User" ;
    //echo $_SESSION['name_of_user'];
}

In my html, I have:

Welcome back <?PHP $fgmembersite->UserName(); ?>!

I also checked the session ID, and it's also being generated properly. Can you please help me understand what I'm doing wrong?

Is fgmembersite an object and have it the function called UserName ?

If yes, you simply miss an echo

<?PHP echo $fgmembersite->UserName(); ?>

You must add echo or print so should look like this;

<?PHP echo $fgmembersite->UserName(); ?>

You need to print out your variable. Use

Echo or print

Possibly you should add output:

<?php print $fgmembersite->UserName(); ?>

If you are using the script I think you are using, you need to look through fg_membersite.php at the line that says:

function CheckLoginInDB($username,$password)

whithin that line you should have a MySQL statement:

$qry = "SELECT etc...

When I tried to add UserAvatar I was able to do that by adding it to that MySQL string.

On a side note, I too am having trouble with adding UserName, and for the life of me I can't figure out why it would work any different than my previous workaround, yet somehow it is, but I am still convinced something in that file will do the trick eventually.

Edited:

Ok i got it, just do this:

echo $fgmembersite->UserName($username);

The username will pop right out. I have no idea why, i don't know enough php to explain it, but i can only assume this will get you going.
