$items = Mage::getSingleton('checkout/cart')->getQuote()->getAllItems();

foreach($items as $item){

}

public function hookToControllerActionPostDispatch($observer)

{

if($observer->getEvent()->getControllerAction()->getFullActionName() == 'checkout_cart_delete' || $observer->getEvent()->getControllerAction()->getFullActionName() == 'checkout_cart_updatePost' ){

$items = Mage::getSingleton('checkout/cart')->getQuote()->getAllItems();

foreach($items as $item){

if ($item->getOriginalCustomPrice()==0 && Mage::getModel('catalog/product')->load($item['product_id'])->getGiftvalue()> Mage::getSingleton('checkout/cart')->getQuote()->getGrandTotal()){

Mage::getSingleton('checkout/cart')->removeItem($item->getId())->save();

}

public function controlQty($observer)

{

$items = Mage::getSingleton('checkout/cart')->getQuote()->getAllItems();

foreach($items as $item){

if ($item->getPrice()==0 && Mage::getModel('catalog/product')->load($item['product_id'])->getGiftvalue()>Mage::getSingleton('checkout/cart')->getQuote()->getGrandTotal()){

Mage::getSingleton('checkout/cart')->removeItem($item->getId())->save();

}

$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()){

if ($item->getOriginalCustomPrice()!=null){

if ($item->getOriginalCustomPrice()==0.00){

$item->setQty(1);

$item->save();

}

public function make_gift($observer)

{

$items = Mage::getModel('checkout/cart')->getQuote()->getAllItems();

$event = $observer->getEvent();

$product = $event->getProduct();

$quote_item = $event->getQuoteItem();

foreach($items as $item){

if (Mage::getModel('catalog/product')->load($item['product_id'])->getGiftvalue() && ($item->getOriginalCustomPrice())){

if ($item->getOriginalCustomPrice()==0.00){

if ($item['sku']==$quote_item['sku']){

$item->setQty(1);

$item->save();

}

if (Mage::app()->getRequest()->getParam('g')){

if (Mage::getModel('catalog/product')->load($quote_item['product_id'])->getGiftvalue()){

if (Mage::getModel('catalog/product')->load($quote_item['product_id'])->getGiftvalue()<Mage::getModel('checkout/session')->getQuote()->getGrandTotal()){
