Грешка в код

[mitko876]

Значи грешката идва от този код

$cookie_name = $config['cookie_name'] . '_user';

$cookie = explode("&&", $_COOKIE[$cookie_name]);

if (($cookie[1] == "")) {

//Check if session exist
$sql_check = "SELECT * FROM " . USERS_ONLINE_TABLE . " 
WHERE username='" . $cookie[1] . "' AND session='" . $cookie[0] . "'";
$query_check = @mysql_query($sql_check, $conn) or die(include "mysql_error.php");
$num_check = mysql_num_rows( $query_check );

if (empty($num_check)) {

$user['username'] = "Anonymous";

setcookie($config['cookie_name'] . '_user', '' . $cookie[0] . '&&' . $cookie[1], time() - $config['session_lenght'], $config['cookie_url']);
} else {

setcookie($config['cookie_name'] . '_user', '' . $cookie[0] . '&&' . $cookie[1], time() + $config['session_lenght'], $config['cookie_url']);

$user['username'] = $cookie[1];
}
} else {

$user['username'] = "Anonymous";
}
?>

и идва от заявката за преброяване то няма грашка но просто кода не си върши работата и не ме настройва като потребител
ето ви и логин кода
