login problem

Du har husket session_start(); i toppen den side du redirecter til?

Prøv evt også at se siden her: http://dk2.php.net/session_start

Many people were having trouble with PHP losing $_SESSION on header redirect. Most of the examples did not set a session id. Before session_start() remember to put a session_id, this way it sets the information to a place, and then calls on it from the same place.

page 1
<?php
session_id('8675309');
session_start();
$_SESSION['username']="USERNAME";
header(redirect......);
?>

page2
<?php
session_id('8675309');
session_start();
echo $_SESSION['username'];
?>

this way will not lose the data since you are telling it where to go and calling on it from the same place.
