Максим,
if (isset($_COOKIE['gskin'])) {
$set_user['skin'] = check($_COOKIE['gskin']);
if ($_COOKIE['verified'] != "ok") {
if (is_file($rootpath . 'theme/' . $set_user['skin'].'/style.css')) {
setcookie("verified", "ok", time() + 3600 * 24 * 365);
} else {
$set_user['skin'] = $set['skindef'];
setcookie("gskin", $set['skindef'], time() + 3600 * 24 * 365);
setcookie('verified', 'ok');
}
}
}Вот так
