Retrieving Child Product IDs for Configurable and Bundle Products in Magento 2
Retrieving Child Product IDs for Configurable and Bundle Products in Magento 2
Retrieving child product IDs in Magento 2 is essential for managing configurable and bundle products effectively. Configurable products link to multiple simple (child) products, while bundle products consist of multiple selectable items. This guide covers how to fetch child product IDs using Magento’s built-in methods, including the Product Repository Interface, Product Link Management Interface, and Type Instance methods.
Retrieving Child Product IDs for Configurable and Bundle Products in Magento 2
In Magento 2, obtaining the IDs of child products associated with configurable and bundle products is straightforward. Here's how you can achieve this:
1. Fetching Child Product IDs for Configurable Products
Configurable products are parent items that link to simple (child) products. To retrieve the IDs of these child products:
Using the Product Repository Interface:
<?php
namespace YourNamespace\YourModule\Model;
use Magento\Catalog\Api\ProductRepositoryInterface;
class ConfigurableProductHelper
{
/**
* @var ProductRepositoryInterface
*/
private $productRepository;
public function __construct(ProductRepositoryInterface $productRepository)
{
$this->productRepository = $productRepository;
}
/**
* Get child product IDs for a configurable product
*
* @param int $configurableProductId
* @return array
*/
public function getChildProductIds(int $configurableProductId): array
{
$configurableProduct = $this->productRepository->getById($configurableProductId);
return $configurableProduct->getExtensionAttributes()->getConfigurableProductLinks();
}
}
</div>
In this code, replace YourNamespace\YourModule with your actual namespace and module name. The getChildProductIds method returns an array of child product IDs associated with the specified configurable product.
2. Fetching Child Product IDs for Bundle Products
Bundle products consist of multiple child items. To retrieve their IDs:
Using the Product Link Management Interface:
<?php
namespace YourNamespace\YourModule\Model;
use Magento\Bundle\Api\ProductLinkManagementInterface;
class BundleProductHelper
{
/**
* @var ProductLinkManagementInterface
*/
private $productLinkManagement;
public function __construct(ProductLinkManagementInterface $productLinkManagement)
{
$this->productLinkManagement = $productLinkManagement;
}
/**
* Get child product IDs for a bundle product
*
* @param int $bundleProductId
* @return array
*/
public function getChildProductIds(int $bundleProductId): array
{
return $this->productLinkManagement->getChildren($bundleProductId);
}
}
Here, getChildProductIds returns an array of child product IDs for the specified bundle product.
3. Fetching Child Product IDs for Bundle Products (Alternative Method)
Alternatively, you can use the product's type instance to get child product IDs:
Using the Product Type Instance:
<?php
namespace YourNamespace\YourModule\Model;
use Magento\Catalog\Model\Product;
use Magento\Bundle\Model\Product\Type as BundleType;
class BundleProductHelper
{
/**
* Get child product IDs for a bundle product
*
* @param Product $bundleProduct
* @return array
*/
public function getChildProductIds(Product $bundleProduct): array
{
if (!$bundleProduct->getTypeId() === BundleType::TYPE_CODE) {
return [];
}
/** @var \Magento\Bundle\Model\Product\Type $typeInstance */
$typeInstance = $bundleProduct->getTypeInstance();
return $typeInstance->getChildrenIds($bundleProduct->getId()) ?? [];
}
}
In this approach, getChildProductIds retrieves child product IDs for the given bundle product.
Note: Ensure that the product IDs you provide are valid and correspond to existing products in your Magento store.
