Magento 2 show custom option price in order email

Question

I have tried to set custom option price when order is placed the price should be stored in sales_order_item table in custom_option column and tried to create plugin for this but the plugin is not working. I have done debug and found that COre magento custom option data is set from this abstract class :

This is magento core function behavior of custom option.

vendor/magento/module-catalog/Model/Product/Type/AbstractType.php

/**
 * Prepare additional options/information for order item which will be
 * created from this product
 *
 * @param \Magento\Catalog\Model\Product $product
 * @return array
 */
 public function getOrderOptions($product)
 {
 $optionArr = [];
 $info = $product->getCustomOption('info_buyRequest');
 if ($info) {
 $optionArr['info_buyRequest'] = $this->serializer->unserialize($info->getValue());
 }
 $optionIds = $product->getCustomOption('option_ids');
 if ($optionIds) {
 foreach (explode(',', $optionIds->getValue()) as $optionId) {
 $option = $product->getOptionById($optionId);
 if ($option) {
 $confItemOption = $product->getCustomOption(self::OPTION_PREFIX . $option->getId());
 $group = $option->groupFactory($option->getType())
 ->setOption($option)
 ->setProduct($product)
 ->setConfigurationItemOption($confItemOption);
 $optionArr['options'][] = [
 'label' => $option->getTitle(),
 'value' => $group->getFormattedOptionValue($confItemOption->getValue()),
 'print_value' => $group->getPrintableOptionValue($confItemOption->getValue()),
 'option_id' => $option->getId(),
 'option_type' => $option->getType(),
 'option_value' => $confItemOption->getValue(),
 'custom_view' => $group->isCustomizedView(), ];
 }
 }
 }
 $productTypeConfig = $product->getCustomOption('product_type');
 if ($productTypeConfig) {
 $optionArr['super_product_config'] = [
 'product_code' => $productTypeConfig->getCode(),
 'product_type' => $productTypeConfig->getValue(),
 'product_id' => $productTypeConfig->getProductId(),
 ];
 }
 return $optionArr;
 }

In this core file if i add this key and value in existing array then i am able to get price in transactional email.

'price' => $group->getOptionPrice($confItemOption->getValue(), 0)

Could any one suggest that how could we save custom option price in order and get it in emails.

Answer 1

For temporary fix i have used the below code in block and used in email items phtml file.

Please Post answer if there is better way available to achieve it.

app/code/[Vendor_Name]/[Module_Name]/view/frontend/templates/email/items.phtml

/**
 * Returns array of Item options
 *
 * @param object $_item
 * @return array
 */
 public function getItemOptions($_item)
 {
 $result = [[]];
 if ($options = $_item->getProductOptions()) {
 if (isset($options['options'])) {
 $result[] = $options['options'];
 }
 if (isset($options['additional_options'])) {
 $result[] = $options['additional_options'];
 }
 if (isset($options['attributes_info'])) {
 $result[] = $options['attributes_info'];
 }
 }
 return array_merge(...$result);
 }
 /**
 * Return option price
 *
 * @param [] $option
 * @return int | bool
 */
 public function getCustomOptionPrice($option)
 {
 $price = null;
 if (isset($option['option_value'])) {
 $optionValueIds = explode(',', $option['option_value']);
 if (!empty($optionValueIds)) {
 foreach ($optionValueIds as $key => $value) {
 $select = $this->resourceConnection->select()->from(
 ['potp' => $this->resourceConnection->getTableName('catalog_product_option_type_price')],
 [
 'potp.price'
 ]
 )->where('potp.option_type_id = ?', $value);
 $result = $this->resourceConnection->fetchRow($select);
 if ($result && isset($result['price'])) {
 $price += $result['price'];
 }
 }
 }
 }
 return $price;
 }

Answer 2

$price = $option['option_value'];
$quoteItem->setCustomPrice($price);
$quoteItem->setOriginalCustomPrice($price);
$product->setIsSuperMode(true);
