Retrieving Selection IDs for Bundle Products in Magento 2
Magento 2's bundle products allow customers to customize their purchases by selecting options and adding items to the cart with a single click. The catalog_product_bundle_selection table stores the relationship between bundle items and their associated child products, including details like option ID, quantity, position, and default item selection.
Understanding the catalog_product_bundle_selection Table
This table links bundle items to their child products. It contains columns such as selection_id, option_id, product_id, and parent_product_id, which are essential for identifying the selection ID based on the bundle item ID and child product ID.
Retrieving the Selection ID
To obtain the selection ID for a specific bundle item and its child product, execute a database query using the following function:
namespace YourNamespace\YourModule\Model;
use Magento\Framework\App\ResourceConnection;
class BundleSelectionId
{
private const BUNDLE_SELECTION_TABLE = "catalog_product_bundle_selection";
private $resourceConnection;
public function __construct(ResourceConnection $resourceConnection)
{
$this->resourceConnection = $resourceConnection;
}
public function getSelectionId(int $bundleItemId, int $childItemId)
{
$tableName = $this->resourceConnection->getTableName(self::BUNDLE_SELECTION_TABLE);
$connection = $this->resourceConnection->getConnection();
$select = $connection->select()
->from(['e' => $tableName], ['selection_id', 'option_id', 'product_id'])
->where("e.product_id = :product_id")
->where("e.parent_product_id = :parent_product_id");
$bind = ['product_id' => $childItemId, 'parent_product_id' => $bundleItemId];
return $connection->fetchRow($select, $bind);
}
}
Usage Example
To retrieve the selection ID for a bundle item with ID 52 and a child product with ID 29, use the following code:
$bundleItemId = 52;
$childItemId = 29;
$selectionId = $this->getSelectionId($bundleItemId, $childItemId);
echo $selectionId;
