Magento: Get the quantity in cart for a given product

Question

I use this code :

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


        

Answer 1

You should use the

setQUote

method when calling the collection. Should looks like this

$quote = Mage::getModel('sales/quote')->load($quote_id);
$salesQuoteItem = Mage::getModel('sales/quote_item')->getCollection()
            ->setQuote($quote)
            ->addFieldToFilter('quote_id', $quote_id)
            ->addFieldToFilter('product_id', $data['product_id'])
            ->getFirstItem();
