Errore con redirect: Cannot modify header...
ciao gente.
mi sapreste aiutare:
ho questo schema:
header.php
starter.php (contiene una parte di scrit per caricare le immagini per la navigazione)
login.php
elabora_login.php
header contiene solo codice html coi css.
starter NON contiene alcn header
login è una pagina html che contiene un form e qualche script per le immagini,
elabora contiene:
Codice PHP:
<?php
include_once('script/check_login.php');
include('header.php');
include('starter.php');
include('script/conn.php');
if(!$_POST['username'] | !$_POST['password']){
echo'<h1 align=center >:: Errore ::</h1>Devi inserire tutti i campi<br>';
echo"<a href=javascript:history.back()>Indietro</a>";
exit;
}
$usern = $_POST['username'];
$query = "SELECT * FROM utenti WHERE username='$usern'";
$check = mysql_query($query);
if(!$check){
die(mysql_error());
}
$row = mysql_fetch_array($check);
if($check && mysql_num_rows($check)<=0){
die("<h1 align=center>:: Errore ::</h1>Non risulti registrato. <br>Torna <a href=javascript:history.back()>Indietro</a> <br>oppure <a href='reg.php'> Registrati</a>.");
}
$passw = md5($_POST['password']);
if($passw != $row['password']){
die('<h1 align=center>:: Errore ::</h1>Password inserita <b>NON</b> corretta!. Torna <a href=javascript:history.back()>Indietro</a> ');
}
else{
header("Refresh: 3; URL=index.php"); //GUARDA QUI
$_SESSION['username'] = $usern;
$_SESSION['password'] = $passw;
if($_POST['auto_log']){
setcookie('autolog','loggato',time()+864000);
setcookie('user',$usern,time()+864000);
setcookie('pw',$passw,time()+864000);
}
echo"<h1>:: Bentornato $usern ::</h1>Login effettuato con successo! Attendi il reindirizzamento in 3 secondi...<br>Oppure <a href=index.php> clicca qui per tornare alla home page</a>.";
}
include("footer.php");
?>
mi sapreste dire perchè al login effettuato con successo, ricevo il classico messaggio d'errore:
Citazione:
Warning: Cannot modify header information - headers already sent by (output started at C:\WM\www\lsdBlogs\starter.php:59) in C:\WM\www\lsdBlogs\login.php on line 30
e la stessa cosa al logout?
ora, posso pure togliere il redirect, ma mi rode!
grazie
