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 = MagentoFrameworkAppObjectManager::getInstance(); 



$product = $objectManager->create('MagentoCatalogApiDataProductInterface');



$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.

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

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

Use MagentoCatalogApiProductRepositoryInterface to get it in your constructor.

Full example:

...

private $productRepository; 

...

public function __construct(

    ...

    MagentoCatalogApiProductRepositoryInterface $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.

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

public function __construct(MagentoCatalogModelProductFactory $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));

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 (MagentoFrameworkExceptionNoSuchEntityException $e){

    // insert your error handling here

}

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

Try this:

/** @var MagentoCatalogModelProductFactory $productFactory */

$product = $productFactory->create();

$product->loadByAttribute('sku', 'my sku');



// $product->load($product->getId()); // may need to do this too,

// see MagentoFrameworkApiAttributeValueFactoryAbstractModel::loadByAttribute

You can try that

$objectManager = MagentoFrameworkAppObjectManager::getInstance(); 



$productRepository = $objectManager->get('MagentoCatalogModelProductRepository');

$productObj = $productRepository->get('<SKU>');



echo $productObj->getId();

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 MagentoCatalogModelProductRepository 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 YourCompanyNameYourModuleNameBlock;



class YourCustomBlock extends MagentoFrameworkViewElementTemplate

{ 

    protected $_productRepository;



    public function __construct(

        MagentoFrameworkViewElementTemplateContext $context, 

        MagentoCatalogModelProductRepository $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 = MagentoFrameworkAppObjectManager::getInstance();



$productRepository = $objectManager->get('MagentoCatalogModelProductRepository');



// 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>';
