}
}
$event = $observer->getEvent();
$product = $event->getProduct();
$cart = $event->getCart();
$data = $event->getInfo();
foreach ($data as $itemId => $itemInfo) {
$item = $cart->getQuote()->getItemById($itemId);
if (!$item) {
continue;
}
if (Mage::getModel('catalog/product')->load($item['product_id'])->getGiftvalue()){
