Hey matteo,
the function "filtra()" which u’ve used in u’r script, i think that is not a native PHP script. I think, that’s might have define in that "filtro.php" file.

Am i right ? If yes, then can u show us u’r "filtro.php" file code… ?

sure, it’s a function for filter possibile exploit.
function filtra($testo) { // funzione che pulisce le stringe per prevenire exploit;
$array = array("", "?>", "", "", "", "", "", "", " $testo = str_replace($array, "", $testo);

Hi Matteo,
I feel u’ve some problem in u’r logic. SO, do one thing…

Just insert some dummy line like :    echo "All is well";  inside u’r registration script to detect how long u’r registration script is executing.


      echo "All is well";  //  it’ll help u to detect u’r registration script is really executing

include "config.php";
include "emailcheck.php";
include "filtro.php";

if(isset($_SESSION[‘username’]) && isset($_SESSION[‘password’]))
  header("Location: index.php");

include "config.php";     
include "emailcheck.php";
include "filtro.php";
      echo "All is well";  //  it’ll help u to detect above 3 line will executing successfully & control coming to next line


if(isset($_SESSION[‘username’]) && isset($_SESSION[‘password’]))
  header("Location: index.php");

Similarly go step by step & try to detect the line from where u’r script is jumping out. This will definitely help to detect the error position. From me it’s getting difficult because due to some language problem in error code…

Matteo, i don’t believe magic in codes… ;)
If u r getting error then there must have something going wrong some where in u’r script. OK, let me see once again to u’r script…

Hey matteo, one thing i noticed in u’r registrati script that , from where u’r all those nested if are starting with this…

if($username == NULL
// This section is empty.  

But, there are nothing in it’s ELSE part. I mean, if user will not enter any thing in that username filed of form then u’r script has code to handle to those part but if one user will enter some thing in that username field then there is nothing in u’r code to handle that part…

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /homepages/35/htdocs/accedi.php:1) in /homepages/35/htdocs/accedi.php on line 2

if(isset($_SESSION[‘username’]) && isset($_SESSION[‘password’])){

if (!empty($_SERVER[‘HTTP_CLIENT_IP’])) {
} elseif (!empty($_SERVER[‘HTTP_X_FORWARDED_FOR’])) {
} else {

$lastdata = mktime();

$username= filtra(trim($_POST[‘username’]));
$password = filtra(trim($_POST[‘password’]));
$check_user_data = mysql_query("SELECT * FROM `members` WHERE `username` = ‘$username’") or die(mysql_error());
if($username == NULL OR $password == NULL){
$final_report="Accesso fallito: dati non inseriti.";
if(mysql_num_rows($check_user_data) == 0){
$final_report="Login failed!";
$get_user_data = mysql_fetch_array($check_user_data);
if($get_user_data[‘password’] !== $password){
$final_report="Login failed!";
$get_user_stato = mysql_fetch_array($check_user_data);
if($get_user_stato[‘stato’] == "0"){
$final_report="Failed: you are banned.";
$get_user_verificato = mysql_fetch_array($check_user_data);
if($get_user_verificato[‘verificato’] == "0"){
$final_report="Your account isn’t verified yet. check inbox.";
$start_idsess = $_SESSION[‘username’] = "".$get_user_data[‘username’]."";
$start_passsess = $_SESSION[‘password’] = "".$get_user_data[‘password’]."";
$update_ip = mysql_query("UPDATE `members` SET lastip =’$ip’ WHERE `username` = ‘$username’") or die(mysql_error());
$update_ip = mysql_query("UPDATE `members` SET lastdata =’$lastdata’ WHERE `username` = ‘$username’") or die(mysql_error());

$final_report=‘Please wait… .redirect’;

Hi Matteo,
That "headers already sent" error also shows due to unknown blank space which exist before HEADER. Check u’r "accedi.php" file’s 1st 3/4 lines(as error report showing error is coming from line-2) carefully for any unknown blank space.

Mhhhh most likely you have reason, last night i made some correction ( including remove the blank line) and now it magically works. Thanks a lot Suresh, you have helped me another time
