Accessing product stock information is essential for managing inventory effectively in any e-commerce store. This data includes crucial details such as the minimum quantity required (min_qty), minimum sale quantity (min_sale_qty), maximum sale quantity (max_sale_qty), and the product's availability status (is_in_stock). In Magento 2, tracking inventory changes is vital for making informed business decisions and ensuring that you meet customer demand.

While Magento 2 provides robust support for inventory management, many store owners may find themselves unsure about the most efficient methods for retrieving this information.

By following the steps outlined in this tutorial, you will learn how to efficiently access the necessary stock data, which can help you maintain optimal inventory levels and improve overall customer satisfaction. Let’s dive into the details and explore how to get product stock information in Magento 2.

2 steps to get product stock information in Magento 2

  • Step 1: Declare the command to retrieve product stock information.
  • Step 2: Load the product ID and SKU in the template file.

Step 1: Declare the command to get product stock information

Begin by utilizing a block class from the module Mavenbird_HelloWorld. In the constructor of the module's block class, you will need to inject the object of the class. 

\Magento\CatalogInventory\Model\Stock\StockItemRepository

Here’s how you can define the block class: 

app/code/Mavenbird/HelloWorld/Block/HelloWorld.php
namespace Mavenbird\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{    
    protected $_stockItemRepository;
        
    public function __construct(
        \Magento\Backend\Block\Template\Context $context,        
        \Magento\CatalogInventory\Model\Stock\StockItemRepository $stockItemRepository,
        array $data = []
    )
    {
        $this->_stockItemRepository = $stockItemRepository;
        parent::__construct($context, $data);
    }
    
    public function getStockItem($productId)
    {
        return $this->_stockItemRepository->get($productId);
    }
}

Step 2: Load product id and sku in template file

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

$id = 123;
$_productStock = $block->getStockItem($id);
//print_r($_productStock->getData()); 
echo $_productStock->getQty(); echo '
';
echo $_productStock->getMinQty(); echo '
';
echo $_productStock->getMinSaleQty(); echo '
';
echo $_productStock->getMaxSaleQty(); echo '
';
echo $_productStock->getIsInStock(); echo '
';
