I am writing an extension where I need to place an order with the items already in the user's cart (added programmatically). I have been successful with this, however my orders lose custom options added via $_product->addCustomOption().

$addOptns['my_custom_option'] = 3;

foreach ($addOptns as $key => $value) {

    $_product->addCustomOption( $key, $value);

}

$params = array(

    'product' => 123, //product Id

    'qty'   => 100    //quantity of product

);

$this->_cart->addProduct(

    $_product,

    $params

);

$this->_cart->save();

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



...[shipping and payment config]...



$order_id = $this->cartManagementInterface->placeOrder($quote->getId());

When I try to receive my_custom_option from the order that is placed, I get null.

var_dump($item->getCustomOptions()); // NULL

Any guess what is wrong with my approach?

Note: This is not a 'custom option' like those created in the admin UI nor do I expect it to be, I use these custom options for other customized processes and they are not directly user selectable.

Order object does not take custom options from quote but you can force it with event

sales_model_service_quote_submit_before

check this tutorial: https://www.cloudways.com/blog/add-additional-options-in-magento-2/. it covers your case completely

You can achieve by a plugin in Magento 2.2.*

First of all, we need to create an observer file and one Magento event file to implement this functionality.

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">

    <event name="catalog_product_load_after">

        <observer name="set_additional_options" instance="CompanyNameModuleNameModelSetAdditionalOptions" />

    </event>    

</config>

Once you have created this file, now you need to Create another file and named as: CompanyNameModuleName/Model/SetAdditionalOptions.php

<?php

namespace CompanyNameModuleNameModel;



use MagentoFrameworkEventObserverInterface;

use MagentoFrameworkAppRequestInterface;

use MagentoFrameworkAppObjectManager;

use MagentoFrameworkSerializeSerializerJson;



class SetAdditionalOptions implements ObserverInterface

{

    protected $_request;    

    public function __construct(RequestInterface $request, Json $serializer = null) 

    {

        $this->_request = $request;

        $this->serializer = $serializer ?: MagentoFrameworkAppObjectManager::getInstance()

            ->get(MagentoFrameworkSerializeSerializerJson::class);

    }



    /**

     * @param MagentoFrameworkEventObserver $observer

     */

    public function execute(MagentoFrameworkEventObserver $observer)

    {

        // Check and set information according to your need

        $product = $observer->getProduct();                    

        if ($this->_request->getFullActionName() == 'checkout_cart_add') { //checking when product is adding to cart

            $product = $observer->getProduct();

            $additionalOptions = ;

            $additionalOptions = array(

                'label' => "Release Date", //Custom option label

                'value' => $product->getReleaseDate(), //Custom option value

            );                        

            $product->addCustomOption('additional_options', $this->serializer->serialize($additionalOptions));

        }

    }



}

Now, We need to create a plugin for the retrieve custom option from cart to order.

First We need to create di.xml.

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <type name="MagentoQuoteModelQuoteItemToOrderItem">

        <plugin name="unique_name" type="CompanyNameModuleNameModelPluginQuoteToOrderItem" sortOrder="1" />

    </type>

</config>

Once you have created this file, now you need to Create another file and named as: CompanyNameModuleNameModelPluginQuoteToOrderItem.php

<?php

namespace ZCompanyNameModuleNameModelPluginQuote;



use MagentoQuoteModelQuoteItemToOrderItem as QuoteToOrderItem;

use MagentoFrameworkSerializeSerializerJson;

class ToOrderItem

{    

    public function __construct(Json $serializer = null) 

    {        

        $this->serializer = $serializer ?: MagentoFrameworkAppObjectManager::getInstance()

            ->get(MagentoFrameworkSerializeSerializerJson::class);

    }



    public function aroundConvert(QuoteToOrderItem $subject,

        Closure $proceed,

        $item,

        $data = 

    ) {

        // Get Order Item

        $orderItem = $proceed($item, $data);               



        $additionalOptions = $item->getOptionByCode('additional_options');        

        // Check if there is any additional options in Quote Item                    

        if (count($additionalOptions) > 0) {

            // Get Order Item's other options

            $options = $orderItem->getProductOptions();

            // Set additional options to Order Item

            $options['additional_options'] = $this->serializer->unserialize($additionalOptions->getValue());

            $orderItem->setProductOptions($options);

        }



        return $orderItem;

    }

}

Retrieve custom options of products present any order

$orderObject = $objectManager->get('MagentoSalesModelOrder'); 



// load by order id

$orderId = 1; // YOUR ORDER ID

$order = $orderObject->load($orderId);



// load by order increment id

// $incrementId = '000000001'; // YOUR ORDER INCREMENT ID

// $order = $orderObject->loadByIncrementId($incrementId);



$items = $order->getAllVisibleItems(); // get all items aren't marked as deleted and that do not have parent item; for e.g. here associated simple products of a configurable products are not fetched



// Order items can also be fetched with the following functions

// $items = $order->getAllItems(); // get all items that are not marked as deleted

// $items = $order->getItems(); // get all items



foreach ($items as $item) {

    $options = $item->getProductOptions();        

    if (isset($options['options']) && !empty($options['options'])) {        

        foreach ($options['options'] as $option) {

            echo 'Title: ' . $option['label'] . '<br />';

            echo 'ID: ' . $option['option_id'] . '<br />';

            echo 'Type: ' . $option['option_type'] . '<br />';

            echo 'Value: ' . $option['option_value'] . '<br />' . '<br />';

        }

    }

}

However, using ObjectManager directly for that is not a great solution. You can still use the code with dependency injection as the below:

• Open the block class Yourcompany_HelloWorld, then inject the object of MagentoSalesModelOrder in the constructor of my module’s block class.

app/code/Yourcompany/HelloWorld/Block/HelloWorld.php

<?php

namespace YourcompanyHelloWorldBlock;

class HelloWorld extends MagentoFrameworkViewElementTemplate

{

    protected $_orderModel;    



    public function __construct(

        MagentoBackendBlockTemplateContext $context,

        MagentoSalesModelOrder $orderModel,

        array $data = 

        )

        {        

            $this->_orderModel = $orderModel;

            parent::__construct($context, $data);

        }



        public function getOrderItems($orderId) 

        {

            $order = $this->_orderModel->load($orderId);

            return $order->getAllVisibleItems();        

        }

}

?>

Like that, you can use the function in the .phtml file.

$orderId = 1; // YOUR ORDER ID

$items = $block->getOrderItems($orderId);



foreach ($items as $item) {

    $options = $item->getProductOptions();        

    if (isset($options['options']) && !empty($options['options'])) {        

        foreach ($options['options'] as $option) {

            echo 'Title: ' . $option['label'] . '<br />';

            echo 'ID: ' . $option['option_id'] . '<br />';

            echo 'Type: ' . $option['option_type'] . '<br />';

            echo 'Value: ' . $option['option_value'] . '<br />' . '<br />';

        }

    }

}

That is all things you will use to retrieve value product custom option cart order in Magento 2.
