Magento 2 : Get backorders and update backorders status by specific product

Question

I want to get back orders by specific product id and update product's back orders status by specific product.

Any help would be appreciated.

Thanks.

Answer 1

You need to inject \Magento\Catalog\Api\ProductRepositoryInterface in your construct for get backorders details by specific product Id. Add this below code in your construct :

protected $productRepository;

public function __construct(
    \Magento\Catalog\Api\ProductRepositoryInterface $productRepository
) {
    $this->productRepository = $productRepository;
}

Now, You need to add this below code in your function.

Get backorders by specific product :

$productId = 1;
$product = $this->productRepository->getById($productId);
$productStock = $product->getExtensionAttributes()->getStockItem();
echo $productStock['backorders'];

Update backorders by specifc product :

$productId = 1;
$product = $this->productRepository->getById($productId);
$stockData = ['backorders' => 1, 'use_config_backorders' => 1];
$product->setStockData($stockData);
$this->productRepository->save($product);

UPDATE:

You can body value which you pass in API get this by this below code :

protected $request;

public function __construct(
\Magento\Framework\Webapi\Rest\Request $request
){
$this->request = $request;  
}

$postBodyData = $this->request->getBodyParams();

Hope, It will helpful for you.

Try below code

$obj = \Magento\Framework\App\ObjectManager::getInstance();  
$stockRegistry = $obj->get('Magento\CatalogInventory\Api\StockRegistryInterface');
$stockitem = $stockRegistry->getStockItem($_product->getId(),$_product->getStore()->getWebsiteId());
echo "Backorder: "; echo $stockitem->getBackorders(); echo '<br>';
