Magento 2.3.4 Load Product by id by any method

Question

In Magento 2 there is more than one method to get product by id. Anyone show me how to get product y in any of the method step by step include files name nd path used.

Answer 1

1. Inject Magento\Catalog\Api\ProductRepositoryInterface in your constructor and assign it to a variable in the class.

 $this->productRepository = $productRepository;

2. Get the product by it's SKU -

 $product = $this->productRepository->get($productSku);

3. Get the product by it's ID -

$product = $this->productRepository->getById($id);

This is the recommended way to access a data from database in Magento.

Answer 2

Add block and Controller file like this

protected $_productloader;

public function __construct(
    ........................................
    \Magento\Catalog\Model\ProductFactory $_productloader,
    ........................................
) {
    ........................................
    $this->_productloader = $_productloader;
    ........................................
}
public function getLoadProduct($id)
{
    return $this->_productloader->create()->load($id);
}

In controler and block you can call using

$product_id = 45;
$data = $this->getLoadProduct($product_id);
print_r($data->getData());

In phtml file call

$product_id = 45;
$data = $block->getLoadProduct($product_id);
print_r($data->getData());

block and phtml link like this (add your block file path )

<block class="VendoreName\ModuleName\Block\YourBlockName" name="prd.data" template="VendoreName_ModuleName::yourfilname.phtml" >

Object method

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->create('Magento\Catalog\Model\Product')->load($product_id);

Factory Method

<?php
namespace Test\Module\Block;

class Product extends \Magento\Framework\View\Element\Template
{

  protected $_productloader;  


  public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Catalog\Model\ProductFactory $_productloader

    ) {


        $this->_productloader = $_productloader;
        parent::__construct($context);
    }
    public function getLoadProduct($id)
    {
        return $this->_productloader->create()->load($id);
    }

}

phtml file code

$product=$this->getLoadProduct(20);
echo $product->getName();


<?php
    namespace Test\Module\Block;
    use Magento\Catalog\Api\ProductRepositoryInterface;
    class Product extends \Magento\Framework\View\Element\Template
     {
          protected $productRepository; 
          protected $_storeManager; 

          public function __construct(
            \Magento\Framework\App\Action\Context $context,
            ProductRepositoryInterface $productRepository
          ) {
              parent::__construct($context);

              $this->productRepository = $productRepository;
          }
          public function getProduct()
          {

              $productId=1;
              return $product = $this->productRepository->getById($productId);
          }
      }

Answer 4

Here I used the easiest way to get the ProductName by ID.

use this code in your Controller <vendor name>/<module>/Controller/Index/Index.php

<?php
namespace <vendor name>\<module>\Controller\Index;
use Magento\Catalog\Model\Product;
use Magento\Framework\App\Action\Context;

class Index extends \Magento\Framework\App\Action\Action
{
 protected $_pageFactory,$productId=731,$productModel;
 public function __construct(Context $context,Product $productModel)
{
 parent::__construct($context);
 $this->productModel = $productModel;
 $this->getProductModel();
}
 public function execute()
{
 return $this->_pageFactory->create();
}
 public function getProductModel()
{
 $product=$this->productModel->load($this->productId);
 echo $product->getName();
 }
}
