ciao..
io sto cercando di fare il login ad un mio sito tramite database sql
una volta che provo a far andare il login mi da questo errore:
Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /Applications/XAMPP/xamppfiles/htdocs/xampp/tesina/login.php:13) in /Applications/XAMPP/xamppfiles/htdocs/xampp/tesina/login.php on line 15
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /Applications/XAMPP/xamppfiles/htdocs/xampp/tesina/login.php:13) in /Applications/XAMPP/xamppfiles/htdocs/xampp/tesina/login.php on line 15
Warning: session_regenerate_id() [function.session-regenerate-id]: Cannot regenerate session id - headers already sent in /Applications/XAMPP/xamppfiles/htdocs/xampp/tesina/login.php on line 17
questo è il mio codice:
la riga 15 in cui mi da errore è quella della session start
la 13 invece è quella con <?php

$result = mysql_query($query, $conn);

$_SESSION['password'] = $password;
} else {

exit;
