Why is it Important to Get Product by ID?
Fetching product data by ID allows for smooth manipulation and display of specific items in Magento 2. Whether you’re building a custom module or working on theme development, knowing how to query product details such as name, price, SKU, and options is key. Luckily, Magento 2 provides a flexible framework to achieve this. Let’s dive into different methods.
1. Get Product by ID Using Factory Method
The most common method for retrieving product data in Magento 2 is by leveraging the Factory Method. This approach is ideal when you need to create objects in a clean and manageable way.
Here’s a sample code snippet to use the Factory method:
protected $_productFactory;
public function __construct(
MagentoCatalogModelProductFactory $productFactory
) {
$this->_productFactory = $productFactory;
}
After injecting the ProductFactory class, you can get the product by ID with the following line of code:
$product = $this->_productFactory->create()->load($productId);
This method is efficient for handling product data on smaller scales or when working within a controller or block.
2. Get Product by ID Using API Repository
A more modern approach in Magento 2 is to use the API Repository to fetch product data. The repository pattern is preferable when working with services or building REST APIs. It allows for more flexibility and adheres to Magento’s Service Contracts.
To fetch a product by ID via the repository, use the following code:
protected $productRepository;
public function __construct(
MagentoCatalogApiProductRepositoryInterface $productRepository
) {
$this->productRepository = $productRepository;
}
public function getProductById($productId) {
return $this->productRepository->getById($productId);
}
The repository method is recommended when handling large-scale operations or complex integrations in Magento 2. It allows for more robustness and reusability in your codebase.
3. Get Product by ID Using Object Manager
Although discouraged in most cases, you can also retrieve product information using the Object Manager. This method bypasses dependency injection, making it less ideal but useful in specific scenarios where you need a quick solution.
Here’s how to use the Object Manager to get product by ID in Magento 2:
$objectManager = MagentoFrameworkAppObjectManager::getInstance();
$product = $objectManager->create('MagentoCatalogModelProduct')->load($productId);
While this method works, it is not recommended for long-term code maintenance as it violates Magento’s best practices for object management.

Conclusion
Knowing how to get product by ID in Magento 2 is an essential skill for any developer working within the Magento ecosystem. Whether you choose the Factory Method, API Repository, or Object Manager, each has its use cases. Understanding these approaches will help you retrieve product data effectively and implement it in your custom solutions.
While Magento offers various options for fetching product data, the recommended method is the API Repository, as it adheres to modern development standards and enhances scalability. However, for simpler tasks, the Factory Method can still be very effective.
By mastering these techniques, you can streamline your Magento 2 development process, making it easier to handle product data with confidence.
