quote id  77.

I have try below blog; Programmatically add items to cart and assign to guest user

Answer 1

Have a look at the merge() method in Mage_Sales_Model_Quote. I've never used it, but it should be something such as:

$quoteA = Mage::getModel('sales/quote')->load('5');
$quoteB = Mage::getModel('sales/quote')->load('77');

$quoteB->merge($quoteA);

// Also?
$quoteB->collectTotals()->save();

Zend_Debug::dump($quoteB->getAllItems());

// edit - I looked at what Magento does in the checkout session model, and it also calls collectTotals() and save(), so that's probably necessary as well.

Have a look also at Mage_Checkout_Model_Session

Just an addition to this, to get the quote items copied over, you need to run the following:

foreach($quoteA->getItemsCollection() as $item) {

   $item->setId(null); //Remove the item id, so it gets added
   $quoteB->addItem($item);
}

I had a similar problem, I wanted to create a new quote in the user's session and copy previous items to it, and it worked for me.

$newQuote = Mage::getModel('sales/quote')->merge($quote);
$newQuote->setStoreId($quote->getStoreId());
$newQuote->collectTotals()->save();
Mage::getSingleton('checkout/session')->replaceQuote($newQuote);
