How to save a Item Object in Magento to get it back later

Question

I want save

$this->_getCart()->getItems()

And save it so i can work with the Items after checkout! After the checkout i want to write the items backk to the cart.

Does anybody has a Idea to proceed?

Answer 1

It was easy:

Mage::getSingleton('core/session')->setData('old_items', serialize($items));

and

$items = unserialize(Mage::getSingleton('core/session')->getData('old_items'));
