post the first 10 lines of code please EXACTLY as they are in your script.

most likely you are printing either characters or white space to the browser before you call your session_start(). session_start() is a header function and needs to be called before anything is printed to the browser. ( even white space )

$familyusername = $_POST['username'];
$password = $_POST['password'];

if((!$familyusername) || (!$password)){
echo "Please enter ALL of the information! <br />";
include '../login/login_form.html';
exit();
}

// Convert password to md5 hash
$password = md5($password);

// check if the user info validates the db
$sql = mysql_query("SELECT * FROM users WHERE username='$familyusername' AND password='$password' AND activated='1'");
$login_check = mysql_num_rows($sql);

if($login_check > 0){
while($row = mysql_fetch_array($sql)){
foreach( $row AS $key => $val ){
$$key = stripslashes( $val );
}
// Register some session variables!
session_register('first_name');
$_SESSION['first_name'] = $first_name;
session_register('last_name');
$_SESSION['last_name'] = $last_name;
session_register('username');
$_SESSION['username'] = $familyusername;
session_register('email_address');
$_SESSION['email_address'] = $email_address;
session_register('special_user');
$_SESSION['user_level'] = $user_level;

PHP Code:

<?
include 'db.php';

session_start();
if (!empty($_SESSION['username'])) {
    print "you are already logged in!";
    include '../family/displaytree.php';
    exit();
}

$familyusername = $_POST['username'];
$password = $_POST['password'];

if((!$familyusername) || (!$password)){
    echo "Please enter ALL of the information! <br />";
    include '../login/login_form.html';
    exit();
}

// Convert password to md5 hash
$password = md5($password);

// check if the user info validates the db
$sql = mysql_query("SELECT * FROM users WHERE username='$familyusername' AND password='$password' AND activated='1'");
$login_check = mysql_num_rows($sql);

if($login_check > 0){
    while($row = mysql_fetch_array($sql)){
    foreach( $row AS $key => $val ){
        $$key = stripslashes( $val );
    }
        // Register some session variables!
        session_register('first_name');
        $_SESSION['first_name'] = $first_name;
        session_register('last_name');
        $_SESSION['last_name'] = $last_name;
        session_register('username');
        $_SESSION['username'] = $familyusername;
        session_register('email_address');
        $_SESSION['email_address'] = $email_address;
        session_register('special_user');
        $_SESSION['user_level'] = $user_level;

have you messed with the permissions on your server lately? now that i look again, it seems as though php does not have permission to access the files in : /tmp/p/o/o/poola.com/

[apoola]

not really, the server is not on my computer.

[sde]

the admin probably screwed up the permissions then.

make a new file and just put this:

PHP Code:

<?
session_start();
?>

save it as test.php and see if you get the same errors.

if you do, inform the admin of that server that they need to fix permissions so you can use sessions with php.

[apoola]

thanks.will try that and get back.

[apoola]

I still got the same kind of message
