Logging in problems - need to login twice?

[downah]

Hi guys, have a little problem here, when you login first it seems to work fine, and redirects back to index.php showing your username etc, but then when I click on another page which checks if session is set, it asks me to login again, so I do that, get redirected back to index.php again and click on the same page and then it works.. but almost every time it asks me to login twice.. and not sure why?

 

Logging in / creating the session :

<?php
// Login
  session_start();
  $_SESSION['username'] = htmlspecialchars($username); // htmlspecialchars() sanitises XSS

header( 'Location: index.php' ) ;
?>

 

then on index.php:

 

<?php
include 'connect.php';
session_start();
$username = $_SESSION['username'];
?>

 

And on another page:

 

<?php
include 'connect.php';
include_once "markdown.php";
session_start();
if(!isset($_SESSION['username']))
{
//code
}
?>

is there anything in markdown.php that could be destroying or resetting the session?

Nope, got rid of markdown and still doing the same..

Shouldnt "session_start();" be at the top of the page? before any includes.

Try that!

 

<?php
session_start();
include('connect.php');
$username = $_SESSION['username'];
?>

 

And if you are including pages that also have session start on them remove session start you will only need it once!
