I want to assign items added to cart by one customer to the other customer's cart.

For this I see two tables responsible for holding that data. One is table named "quote" and other is "Quote_item".The customer in which I want to transfer the cart item already has a quote created on quote table. so I thought changing the quote_id of that customer on quote_item table would do the trick.

Let me explain by example:

Let us assume we have two customer with quote id 1 and 2.
Customer 1 added a product to the cart so on quote_item table the item will be saved with quote id 1. so if I could change the quote id of that item to 2 than that product will be assigned to customer 2.

I tried it by manually changing to the database and it worked. But When I tried to update that table programatically than it couldn't update the row. I think there is some kind of dependencies that I couldn't figure out.So I hope if someone could help me figure it out.

Below is the update code that I have written.

$_objectManager = MagentoFrameworkAppObjectManager::getInstance();



$quoteItemModel = $_objectManager->create('MagentoQuoteModelQuoteItem');

//filter the product with same quote id     

        $productCollection = $_objectManager->create('MagentoQuoteModelResourceModelQuoteItemCollection')->addFieldToFilter('quote_id',$quoteId);

            if($products = $productCollection->getData()){

                foreach ($products as $product) {

                    $itemId = $product['item_id'];

                    $data = array();

                    //just putting a static value to check if the data gets updated

                    $data['quote_id']='2';

                    //updating the quote_item table

                    $quoteItemModel->load($itemId)->addData($data);

                    try {

                        $quoteItemModel->setId($itemId)->save();

                        echo "Data updated successfully.";



                    } catch (Exception $e){

                        echo $e->getMessage(); 

                     }

                    }

I know the code works perfectly with other custom tables.But in this case it is not updating the data.
Its gives below error:

Fatal error: Call to a member function getStoreId() on null in
E:xampphtdocs...vendormagentomodule-quoteModelQuoteItemAbstractItem.php
on line 144

When I checked that file. The function is:

 public function getProduct()

    {

        $product = $this->_getData('product');

        if ($product === null && $this->getProductId()) {

            $product = clone $this->productRepository->getById(

                $this->getProductId(),

                false,

                $this->getQuote()->getStoreId()

            );

            $this->setProduct($product);

        }

I don't understand what it has to do with the update of table quote_item.I think there is some foreign key constraints or some dependency which is why it is not letting me update the quote_id of quote_item table.

Can some genius mind please help me out here or clearify what could have possibly gone wrong?

Actually I searched the whole internet and also posted question on stackoverflow about the migration of customer cart from one customer to another but still I haven't got a perfect working solution for it.

If someone could help me on this, it would be greatly appreciated.

Thanks.

could you explain more your task ? the customer 1 has to keep his quote and items ? and the customer 2 just have the same items than the customer 1 that's it?
In this case just use the addProduct method which take 2 parameters ($product, $qty).

Get the items from customer 1's quote. Loop on it, and add product to your customer 2's quote.
