Ciao, questo codice fa la stessa cosa, proprio su un forum.
Studialo ed adattalo alle tue esigenze.
Codice PHP:
<?php
include("inc/header.inc.php");
if ($SGET[step] == "2" AND $_SESSION[username] == "") {
############################
$_POST[username] = str_replace(">", ">", $_POST[username]);
$_POST[username] = str_replace("<", "<", $_POST[username]);
$_POST[password] = md5($_POST[password]);
$query_user = "SELECT username,id,type FROM $table_users WHERE username=\"$_POST[username]\" AND password=\"$_POST[password]\"";
$result_user = mysql_query($query_user, $db);
$row_user = mysql_fetch_array($result_user);
if ($row_user[username] != "") {
$_SESSION[username] = "$_POST[username]";
$_SESSION[user_id] = "$row_user[id]";
$_SESSION[type] = "$row_user[type]";
$q = "UPDATE $table_users SET last_login=\"Date: $date2 \n Ip: $ip\" WHERE id=\"$_SESSION[user_id]\"";
mysql_query($q, $db);
#####COOKIE########

setcookie("user_id","$row_user[id]",$current_time + 31536000);
// Mod By Neoscript
// Possibilità di loggarsi tramite modifica del cookies con account di altri senza password
// Scrivo nel cookie un nuovo campo con un nuovo valore che poi servira nel login automatico
setcookie("password","$_POST[password]",$current_time + 31536000); // Mod By Neoscript
