I need to add new option for item.

Now in quote_item_option i have:

{"id":"54","product":"54","selected_configurable_option":"","related_product":"","options":{"4":""},"qty":"1"}

But wanna {"id":"54","product":"54","selected_configurable_option":"","related_product":"","options":{"4":"", "new_option":"some_value"},"qty":"1"}

I created following controller:

<?php



   namespace MySpaceSomeModuleControllerQuote;

    class Index extends MagentoFrameworkAppActionAction

    {

        /**

         * @var MagentoFrameworkControllerResultJsonFactory

         */

        protected $resultJsonFactory;



        /**

         * @var MagentoCheckoutModelSession

         */

        protected $checkoutSession;



        /**

         * Update constructor.

         * @param MagentoFrameworkAppActionContext $context

         * @param MagentoFrameworkControllerResultJsonFactory $resultJsonFactory

         * @param MagentoCheckoutModelSession $checkoutSession

         */

        public function __construct(

            MagentoFrameworkAppActionContext $context,

            MagentoFrameworkControllerResultJsonFactory $resultJsonFactory,

            MagentoCheckoutModelSession $checkoutSession

        ) {

            parent::__construct($context);

            $this->resultJsonFactory = $resultJsonFactory;

            $this->checkoutSession = $checkoutSession;

        }



        /**

         * @return MagentoFrameworkControllerResultJson

         */

        public function execute()

        {

            $a = 3;

            $itemId = (int) $this->getRequest()->getParam('item_id');

            $orderNoteEnabledValue = (string) $this->getRequest()->getParam('new_option');



            if ($itemId && $newOptionValue) {

                $quote = $this->checkoutSession->getQuote();

                /** @var MagentoQuoteModelQuoteItem $item */

                foreach ($this->checkoutSession->getQuote()->getItems() as $item) {

                    if ((int)$item->getItemId() !== $itemId) {

                        continue;

                    }

                    $buyRequest = $item->getBuyRequest();



                    $options = $buyRequest->getData('options');

                    if (!$options) {

                        $options = ;

                    }

                    $options['new_option'] = $newOptionValue;

                    $buyRequest->setData('options', $options);



                    $quote->updateItem($itemId, $buyRequest);

                    $quote->save();



                    break;

                }

            }



            return $this->resultJsonFactory->create()->setData(['message' => 'Error']);

        }

    }

I debugged, script getts data(option value) successfully, modified it also, but not saving option with new field to table.

What is issue or my mistake?

Thanks for any halp and advise:)

Try calling $item->saveItemOptions() instead of (or along side with) $quote->save()
