thank you for your help
That's exactly what i think i'm doing. The problem is that with register_globals OFF it works, and because in my host they'r ON, then it doesnt work; while i wait for a response from them, i use cookies...
here's my code:
<?php session_start();
$checkbox=$_POST['cookieuser'];
if (isset($checkbox)) {
$expiry = 60*60*24*365;
setcookie('uid', $_POST['uid'], time()+$expiry, "/" );
setcookie('pwd', $_POST['pwd'], time()+$expiry, "/" );
}
$uid=isset($_POST['uid']) ? $_POST['uid'] : $_SESSION['uid'];
$pwd=isset($_POST['pwd']) ? $_POST['pwd'] : $_SESSION['pwd'];
if (isset($_POST['uid'])) {
$_SESSION['uid'] = $_POST['uid'];
$_SESSION['pwd'] = $_POST['pwd'];
}
include("common.php"
;
include("db.php"
;
if ($_COOKIE['uid']) { $uid=($_COOKIE['uid']);
$pwd=($_COOKIE['pwd']);
}
if(!isset($uid)) {
?>

<?php
exit;
}
$_SESSION['uid'] = $uid;
$_SESSION['pwd'] = $pwd;
dbConnect("***"
;// function that deals with database credentials
$sql = "SELECT * FROM autores WHERE nome = '$uid' AND palavrapasse = '$pwd'";
$result = mysql_query($sql);
if (!$result) {

}
$id=mysql_result($result,0,"id"

if (mysql_num_rows($result) == 0) {

}
unset($_SESSION['uid']);
unset($_SESSION['pwd']);
