Question

What is wrong with this login script? I have a modal-style iframe login box which is /login.php and I have a /index.php.

After logging in, the login.php redirects to the index.php, but I don’t see the username. just Hello Guest. When I try to login it says you, username, are already logged in.

login.php:

<?php session_start(); require_once('connections/Main.php');

if(isset($_SESSION['username'])) {

    echo '<div class="error_message">Attention! You, '.$_SESSION['username'].' are already logged in.</div>';
    echo "<br />";
    echo "Go <a href='javascript:history.go(-1)'>back</a> to the page you were viewing before this.</li>";

    exit();
}
?>

index.php:

<?php session_start(); 
   require_once('connections/Main.php'); 
     ?>

<div> Hello <?php   if(isset($_SESSION['username'])) { 
          echo $_SESSION['username']; }
                    else{ echo 'Guest'; } ?></div>

Answer 1

start your session with this.

$_SESSION["im_going_in"]=true; 
$_SESSION["username"]=$username;//get data from db.

index.php

<?php
if($_SESSION["im_going_in"]) {
?>

  <?=strtoupper($_SESSION["username"])?>// welcome dear bla bla...

<?
}
?>
