Magento 2 : Adding Custom Attribute "color" to Order Items in Backend

Question

How do I add custom attribute "color". I have made to order items in backend.

I have tried:

• $_item->getColor()
• $_item->getAttributes()
• $_item->getAttribute('color')

And a bunch of other stuff:

vendor\magento\module-sales\view\adminhtml\templates\items\column\name.phtml

<?php
/**

 * See COPYING.txt for license details.
 */

// @codingStandardsIgnoreFile

?>
<?php
/**
 * @see \Magento\Sales\Block\Adminhtml\Items\Column\Name
 */
?>

<?php if ($_item = $block->getItem()): ?>
    <div id="order_item_<?php /* @escapeNotVerified */ echo $_item->getId() ?>_title"
         class="product-title">
        <?php echo $block->escapeHtml($_item->getName()) ?>
    </div>

    <div class="product-sku-block">
        <span><?php /* @escapeNotVerified */ echo __('SKU') ?>:</span> <?php echo implode('<br />', $this->helper('Magento\Catalog\Helper\Data')->splitSku($block->escapeHtml($block->getSku()))); ?>
    </div>

    <?php if ($block->getOrderOptions()): ?>
        <dl class="item-options">
            <?php foreach ($block->getOrderOptions() as $_option): ?>
                <dt><?php /* @escapeNotVerified */ echo $_option['label'] ?>:</dt>
                <dd>
                    <?php if (isset($_option['custom_view']) && $_option['custom_view']): ?>
                        <?php /* @escapeNotVerified */ echo $block->getCustomizedOptionValue($_option); ?>
                    <?php else: ?>
                        <?php $_option = $block->getFormattedOption($_option['value']); ?>
                        <?php /* @escapeNotVerified */ echo $_option['value']; ?><?php if (isset($_option['remainder']) && $_option['remainder']): ?><span id="<?php /* @escapeNotVerified */ echo $_dots = 'dots' . uniqid()?>"> ...</span><span id="<?php /* @escapeNotVerified */ echo $_id = 'id' . uniqid()?>"><?php /* @escapeNotVerified */ echo $_option['remainder'] ?></span>
                            <script>
                                require(['prototype'], function() {
                                    $('<?php /* @escapeNotVerified */ echo $_id ?>').hide();
                                    $('<?php /* @escapeNotVerified */ echo $_id ?>').up().observe('mouseover', function(){$('<?php /* @escapeNotVerified */ echo $_id ?>').show();});
                                    $('<?php /* @escapeNotVerified */ echo $_id ?>').up().observe('mouseover', function(){$('<?php /* @escapeNotVerified */ echo $_dots?>').hide();});
                                    $('<?php /* @escapeNotVerified */ echo $_id ?>').up().observe('mouseout',  function(){$('<?php /* @escapeNotVerified */ echo $_id ?>').hide();});
                                    $('<?php /* @escapeNotVerified */ echo $_id ?>').up().observe('mouseout',  function(){$('<?php /* @escapeNotVerified */ echo $_dots ?>').show();});
                                });
                            </script>
                        <?php endif; ?>
                    <?php endif; ?>
                </dd>
            <?php endforeach; ?>
        </dl>
    <?php endif; ?>
    <?php echo $block->escapeHtml($_item->getDescription()) ?>
<?php endif; ?>

Answer 1

Item object has a product property that you can retrieve by

       `$product = $_item->getProduct();
        $color = $product->getData('color');

Make sure that $_item is instance of Magento\Sales\Model\Order\Item

Answer 2

Try this

$objectManager = Magento\Framework\App\ObjectManager::getInstance();

$product = $objectManager->create('Magento\Catalog\Model\Product')->load($_item->getProductId());

$color = $product->getAttributeText('color');

Answer 3

It worked for me. for get value from drop-down attribute:

$color = $product->getAttributeText('color');

instead of:

$color = $product->getData('color');
