Am acest script si am urmatoarea eroare pe php 4.3.3
<?php
session_start();

$user_name = $_POST['user_name'];
$password = $_POST['password'];

$db_user = 'xxx';
$db_pass = 'xxx';
//connect to the DB and select the "dictator" database
$connection = mysql_connect('localhost', $db_user, $db_pass) or die(mysql_error());
mysql_select_db('xxx', $connection) or die(mysql_error());
//set up the query
$query = "SELECT * FROM admin WHERE user='$user_name' AND pass='$password'";
$result = mysql_query($query, $connection) or die('error making query');
$affected_rows = mysql_num_rows($result);
//run the query and get the number of affected rows
$result = mysql_query($query, $connection) or die('error making query');
$affected_rows = mysql_num_rows($result);
//if there's exactly one result, the user is validated. Otherwise, he's invalid
if($affected_rows == 1) {
$row = mysql_fetch_row($result);
$_SESSION['username'] = $user_name;
$to = "saptamana.php";
header('Location: '. $to);
exit;
}
else {
print 'User sau parola GRESIT. Va rugam mai incercati <br>';
echo "<form name=login method=post action=validate.php>
<div align=center>username:
<input type=text name=user_name>
<br>
password:
<input type=password name=password>
<br>
<input type=submit value=submit>
</div>
</form>";
}
?>
EROARE:

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/mancare/public_html/validate.php:12) in /home/mancare/public_html/validate.php on line 22

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/mancare/public_html/validate.php:12) in /home/mancare/public_html/validate.php on line 22

CE ar trebuie sa fac??? Poate sa ma ajute cineva?

Problema ta e foarte simpla. Nu ma uit peste cod din lipsa de timp, dar stiu sigur ce e gresit. Undeva inainte de session_start(), este trimis ceva text catre browser, care poate fi si un singur caracter. Daca te uiti la eroare, iti spune si linia unde trimiti text catre browser [ 22 ]

ai rezolvat problema intre timp ? daca nu, ce versiune de php folosesti ??

[computershop]

ma scuzi am vazut pe urma ca 4.3.3. de aici e problema din fisierul de configurare a php-ului <<php.ini>> . Nu mai stiu foarte bine dar uita-te ca exista in sectiunea [session] ai o chesatie de genul auto.start.sesion = 0, pune-o pe 1 si o sa mearga.

m-am dat si eu cu capul de pereti:
Cod:
 echo '<pre>';
session_start();
$_SESSION['error_message'][] = 'No Upload!';
print_r($_SESSION);

si nu intelegeam de ce !!!
Merci pentru raspuns si lui google :)

Un mic sfat: Incercati eventual sa folositi ob_start() si ob_end_flush() / ob_flush() ca sa scapati permanent de probleme de genul acesta.
