Avatar van SvenP PHP interesse header probleem is opgelost, dankje 

echter maakt hij de cookie niet aan

Avatar van Thomas Moderator if($b_cookie == ON)

wordt dat dan wel uitgevoerd ? Alles uit $_POST is tekst.

Maak je trouwens gebruik van secure pagina's (https) ? Anders moet je die 1 in je cookie weglaten lijkt mij ? En dat subdomein / subdirectory... Ik weet zo gauw niet of dat goed is - haal dat eens weg en probeer het opnieuw.

Avatar van Legolas Onbekend over het algemeen is het een beetje slecht gescript, dit is beter:
php code - Bekijk de code zonder highlighting - Klap code in 
  1. <?php
  2. if($_SESSION){
  3.     $message = "You are already logged in.";    
  4. }
  5. else{
  6. if($_SERVER['REQUEST_METHOD'] == 'POST'){
  7.     $username = $_POST['username'];
  8.     $password = md5($_POST['password']);
  9.     $b_cookie = $_POST['cookie'];
  10.         $query = mysql_query("SELECT * FROM `ts_members` WHERE `username`='".$username."' AND `password`='".$password."'");
  11.         $check = mysql_fetch_assoc($query);
  12.         if(mysql_num_rows($query) != 0 && $check['activated'] == 1){
