How to load product by SKU in magento 2

Question

It's pretty basic, but I can’t find a working example on Stackexchange or google. I want to load a product from a helper or block. I already tried some things like:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 

$product = $objectManager->create('\Magento\Catalog\Api\Data\ProductInterface');

$product->get('<SKU>');

$product->getName();

This returns nothing. I also tried loading any available models and API’s, but nothing seems to work with SKU’s.

Answer 1

The correct way, according to Magento 2 service contracts, is using repositories:

$product = $this->productRepositoryInterface->get($sku);

Use Magento\Catalog\Api\ProductRepositoryInterface to get it in your constructor.

Full example:

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

public function loadMyProduct($sku)
{
    return $this->productRepository->get($sku);
}
...

Note:

If the product does not exists, this method triggers a NoSuchEntityException error as it would be in the best Magento2 practice.

So, if you need to handle somehow, wrap it in a try/catch block.

Answer 2

Instead of using the object manager directly, inject the ProductFactory:

public function __construct(\Magento\Catalog\Model\ProductFactory $productFactory)
{
    $this->productFactory = $productFactory;
}

Then use it like this:

$product = $this->productFactory->create();
$product->loadByAttribute('sku', $sku);

or to do a full load (the above loads it using a collection):

$product = $this->productFactory->create();
$product->load($product->getIdBySku($sku));

Answer 3

I like @phoenix128-riccardot 's answer, but would add an exception, just in case the product does not exist:

try {
    $product = $this->productRepositoryInterface->get($sku);
} catch (\Magento\Framework\Exception\NoSuchEntityException $e){
    // insert your error handling here
}

I was not able to add it as a comment (too low reputation), sorry.

You can try that

$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 

$productRepository = $objectManager->get('\Magento\Catalog\Model\ProductRepository');
$productObj = $productRepository->get('<SKU>');

echo $productObj->getId();

Answer 5

Try this:

/** @var \Magento\Catalog\Model\ProductFactory $productFactory */
$product = $productFactory->create();
$product->loadByAttribute('sku', 'my sku');

// $product->load($product->getId()); // may need to do this too,
// see \Magento\Framework\Api\AttributeValueFactory\AbstractModel::loadByAttribute

Using Dependency Injection (DI)

Here is the example code to get the product information by product Id and SKU in Magento 2 using dependency injection.

In this, we might need to inject the object of the \Magento\Catalog\Model\ProductRepository class in the constructor of our module’s block class and access it from the view ( .phtml ) file.

Sample File Path: app/code/YourCompanyName/YourModuleName/Block/YourCustomBlock.php

<?php
namespace YourCompanyName\YourModuleName\Block;

class YourCustomBlock extends \Magento\Framework\View\Element\Template
{ 
    protected $_productRepository;

    public function __construct(
        \Magento\Framework\View\Element\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);
    }
}

Now, we can use the functions in our view (.phtml) file as follows.

// get product by id
$product = $block->getProductById(15);

// get product by sku
$product = $block->getProductBySku('MT12');

echo $product->getEntityId() . '<br>';
echo $product->getName() . '<br>';
echo $product->getSKU() . '<br>';
echo $product->getPrice() . '<br>';
echo $product->getSpecialPrice() . '<br>';
echo $product->getTypeId() . '<br>';
echo $product->getProductUrl() . '<br>';

Using Object Manager

Here is the example code to get the product information by product id and SKU in Magento 2 using object manager.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$productRepository = $objectManager->get('\Magento\Catalog\Model\ProductRepository');

// get product by product id 
$product = $productRepository->getById(15);

// get product by product sku 
$product = $productRepository->get('MT12');

echo $product->getEntityId() . '<br>';
echo $product->getName() . '<br>';
echo $product->getSKU() . '<br>';
echo $product->getPrice() . '<br>';
echo $product->getSpecialPrice() . '<br>';
echo $product->getTypeId() . '<br>';
echo $product->getProductUrl() . '<br>';

<?php
use Magento\Framework\App\Bootstrap;
require __DIR__ . '/app/bootstrap.php';
$bootstrap = Bootstrap::create(BP, $_SERVER);
$obj = $bootstrap->getObjectManager();
$state = $obj->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');


$sku ='24-MB01';
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$productObject = $objectManager->get('Magento\Catalog\Model\Product');
$product = $productObject->loadByAttribute('sku', $sku);
echo $product->getName();
