Spiltting Magento Order Error: Invalid method Mage_Sales_Model_Quote::removeItemByKey()

Question

I'm spliting the magento order separately like different vendors, I'm fallowing the Vinai Answer from previous post. But it's returning an error.

Error: Invalid method Mage_Sales_Model_Quote::removeItemByKey()

Mage_Sales_Model_Quote this class have this method but it's returning error WHY?

my code is

<?php

class Easylife_SplitOrder_Model_Type_Onepage extends Mage_Checkout_Model_Type_Onepage
{

    public function saveOrder()
    {
        $quote = $this->getQuote();

        // First build an array with the items split by vendor
        $sortedItems = array();
        foreach ($quote->getAllItems() as $item) {
            //$vendor = $item->getProduct()->getVendor(); // <- whatever you need
            $product = Mage::getModel('catalog/product')->load($item->getProductId());
            //Mage::log($product->getVendor());
            $vendor = $product->getVendor();
            if($vendor != 0){
                if (! isset($sortedItems[$vendor])) {
                    $sortedItems[$vendor] = $item;
                    //Mage::log('vendor');
                }
            }
            //Mage::log('$vendor');
        }

        Mage::log('One');
        foreach ($sortedItems as $vendor => $items) {
            // Empty quote
            foreach ($quote->getAllItems() as $item) {
                $quote->removeItemByKey($item->getId());
            }
            foreach ($items as $item) {
                $quote->addItem($item);
            }
            // Update totals for vendor
            $quote->setTotalsCollectedFlag(false)->collectTotals();

            // Delegate to parent method to place an order for each vendor
            parent::saveOrder();
        }
        Mage::log('2');
        return $this;
    }

}

How can I solve this?

Thanks in advance..

Answer 1

Mage_Sales_Model_Quote::removeItemByKey()

This method doesn't quite exist in Mage_Sales_Model_Quote in Magento and this is why you are getting this error.

Answer 2

The function removeItemByKey can be found on the class Varien_Data_Collection. This means that is is a core function for collection objects. The class Mage_Sales_Model_Quote is not a collection object and so does not have this class.

I think what you want is removeItem this will take the id of the item you wish to remove and removes the item.

$quote->removeItem($item->getId());

Answer 3

What Vinai wrote is:

$quote->getItemsCollection()->removeItemByKey($item->getId());
