How to Get Product by ID, SKU in Magento 2

Getting product id and sku in Magento 2 brings you the exact Product ID number and SKU which are corresponding to the item you want to find. All you have to do is using the following commands in the admin console of your Magento 2 store. Mageplaza makes a great effort to write this topic, and we hope it will help you be clear about how to get the product ID and SKU in Magento 2.

How to get product by ID or SKU in Magento 2

Method 1: Use Construct

Step 1: Declare the command to get product ID or SKU

You will use a block class of the module Mageplaza_HelloWorld, then possibly inject the object of \Magento\Catalog\Model\ProductRepository class in the constructor of the module’s block class.

app/code/Mageplaza/HelloWorld/Block/HelloWorld.php

<?php
namespace Mageplaza\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{	
	protected $_productRepository;
		
	public function __construct(
		\Magento\Backend\Block\Template\Context $context,		
		\Magento\Catalog\Model\ProductRepository $productRepository,
		array $data = []
	)
	{
		$this->_productRepository = $productRepository;
		parent::__construct($context, $data);
	}
	
	public function getProductById($id)
	{
		return $this->_productRepository->getById($id);
	}
	
	public function getProductBySku($sku)
	{
		return $this->_productRepository->get($sku);
	}
}
?>

Step 2: Get product by ID or SKU in template file

Next, please use the below script to get product by id and sku in the template file.

$id = YOUR_PRODUCT_ID;
$sku = 'YOUR_PRODUCT_SKU';
$_product = $block->getProductById($id);
$_product = $block->getProductBySku($sku);
echo $_product->getEntityId();
echo '<br />';
echo $_product->getName();

Method 2: Use ObjectManager

The second method that you should consider is using ObjectManager. You can use it like this:

$bootstrap = \Magento\Framework\App\Bootstrap::create(BP, $_SERVER);
    $objectManager = $bootstrap->getObjectManager();
    $appState = $objectManager->get('\Magento\Framework\App\State');
    $appState->setAreaCode('frontend');
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();

    $productsku = "product_sku"; // add Your SKU here
    $product = $objectManager->get('\Magento\Catalog\Model\ProductRepository')->get($productsku);
   echo $product->getId();

Which method to choose?

Both can meet the need to get product by ID and SKU just fine. What’s important is which one you feel more confident in. However, if you’re still confused, we would like to suggest you use the second option because:

• Magento 2 standards: Avoid direct use of ObjectManager.
• Better performance: Dependency Injection is optimized.
• Easier testing: You can mock ProductRepository for unit tests.
• Clean and maintainable code: Clear and extensible.
