Loginscriptet:<?php
require_once('connect.php');
if ($_POST['action'] == "login") {
$data = mysql_query("SELECT * FROM brugere WHERE login = '" . $_POST['login'] . "' AND password = '" . $_POST['password'] . "'") or die(mysql_error());
$num = mysql_numrows($data);
$row = mysql_fetch_array($data);
if($num == 0){
header("location: login.php?error=1");
echo "Du har indtastet forkert brugernavn/password";
} else {
session_start();
$_SESSION["brugernavn"] = $_POST['login'];
$_SESSION["password"] = $_POST['password'];
$_SESSION["level"] = $row['level'];
header("location: brugerside" . $_SESSION['level'] .".php");
exit;
}
}
switch ($_GET['error']) {
case "1":
echo "<font color='#FFFFFF'>Du har indtastet forkert brugernavn/password.</font>";
break;
case "2":
echo "<font color='#FFFFFF'>Du er ikke logget ind.</font>";

Skriver jeg bruger og password rigtigt får jeg denne besked! :
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at logon.php:2) in logon.php on line 12
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at logon.php:2) in logon.php on line 12
Warning: Cannot modify header information - headers already sent by (output started at logon.php:2) in
Og skriver jeg det bare forkert så siger den:
Warning: Cannot modify header information - headers already sent by (output started at logon.php:2) in logon.php on line 9
Du har indtastet forkert brugernavn/password
I må meget gerne hjælpe :)
