How to get cart item details in event observer?

Question

I'm using an event observer which fires when user clicks on the 'Place Order' button in checkout flow. I want to capture the product details which are in the cart. Actually this moment order object has already created. If I can access order object it is more than enough.

I have tried the followings, but no luck.

I'm using the event checkout_submit_all_after. And that event executes the following function in the observer.

public function galileo_booking_request(Varien_Event_Observer $observer)
    {
       // $product = $observer->getData('product');// returns null object
      //   $order = $observer->getEvent()->getOrder();// returns null object
           $request = $observer->getEvent()->getRequest()->getParams();// returns null object
           Mage::log($request['product'],null,'eventoberver.log',true);
    }

Answer 1

The observer receives as a parameter the order (or orders for multishipping) and the quote. Here is how you can get them

public function galileo_booking_request(Varien_Event_Observer $observer) {
    $order = $observer->getEvent()->getOrder(); //I don't know why this returns null for you. It shouldn't
    //or for multishipping
    //$order = $observer->getEvent()->getOrders(); //you should get an array of orders
    //for the quote
    $quote = $observer->getEvent()->getQuote();
}

If it doesn't work for you for the order, try with the quote. After getting the quote object your can loop through the items.

foreach ($quote->getAllItems() as $item) {
    $product = $item->getProduct();//if you need it
    //your magic here.
}

Answer 2

When using one-page checkout your should be able to get the order, quote and recurring profiles.

Mage::dispatchEvent(
    'checkout_submit_all_after',
    array('order' => $order, 'quote' => $this->getQuote(), 'recurring_profiles' => $profiles)
);

In your observer you can use the $observer->getEvent()->getOrder() and $observer->getEvent()->getQuote() to get the information you need.
