How to Get Value of Product Custom Option from Cart & Order in Magento 2

If you are wondering how to get the value of product custom option from cart and order in Magento 2, this is the right place for you to learn that. Published by Mageplaza, this topic will point you how to do that with two examples as the following.

Firstly, you can use ObjectManager:

  • Get custom options of products present in shopping cart
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$cart = $objectManager->get('\Magento\Checkout\Model\Cart'); 
 
// get cart items
$items = $cart->getItems();
 
// get custom options value of cart items
foreach ($items as $item) {
    $options = $item->getProduct()->getTypeInstance(true)->getOrderOptions($item->getProduct());
    $customOptions = $options['options'];
    if (!empty($customOptions)) {
        foreach ($customOptions as $option) {
            $optionTitle = $option['label'];
            $optionId = $option['option_id'];
            $optionType = $option['type'];
            $optionValue = $option['value'];
        }
    }
}
  • Retrieve custom options of products present any order
$orderObject = $objectManager->get('\Magento\Sales\Model\Order'); 
 
// 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 the great solution. You can still use the code with dependency injection as the below:

  • Open the block class Mageplaza_HelloWorld, then inject the object of \Magento\Sales\Model\Order in the constructor of my module’s block class.

app/code/Mageplaza/HelloWorld/Block/HelloWorld.php

<?php
namespace Mageplaza\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
    protected $_orderModel;    
    
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,
        \Magento\Sales\Model\Order $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 />';
        }
    }
}
