Return username from MySQL

[Cat]

Hei. Sorry for bad english.
I use

You must be registered for see links

(from here) and I don't know how to return something like "Welcome {username}". I've tried with print_r ($_SESSION); but returns Array ( [loggedin] => 1 ).
Please help me! Also, if it's possible to have a page like user.php?user={username} when show informations about {username}. Thanks!

$_SESSION['username']

$_SESSION['username']

Notice: Undefined index: username in www\1\index.php on line 5
Line 5: echo 'Hi', $_SESSION['username'];.

From what I see, $ _SESSION can only return 0 (if not connected) or 1 (if connected).

After reading through the login.php file for the script you mentioned, it does not register a variable called username in the global $_SESSION variable. To fix this, add this to your login.php

$_SESSION['username'] = $username;

right below the $_SESSION['loggedin'] = "1";

Thanks for reply. I added $_SESSION['username'] = $username; after $_SESSION['loggedin'] = "1"; and before header("Location: index.php"); but still don't work; same error.

Are you sure you logged out (reset session) and tried again?

You need to be checking if they logged in first before echoing that. Look at main.php

Hey there, <?=$_SESSION['username']?>!

No problem

Unfortunately this thread is made in a request section, so you can't mark my answer as the best answer. The thread would have to be moved to a Help section.

The shorthand echo method in PHP isn't advised, some web servers don't allow it.

But it seems this problem is sorted. Closed. (also moved to help & support)
