Magento 2 – How to Display Stock Quantity on Grouped Product

magento-2.1magento2quantity

I need to display Stock Quantity on grouped products.

Grouped product detail are displaying by grouped.phtml

(Core module: module-grouped-product/view/frontend/templates/product/view/type/grouped.phtml).

I have extended this module and i need to display Quantity there.

Update: This is foreach loop that display products and I need to display Stock qty in for-each loop.

I am not sure If i can display from function reference of stock.

Line 34 – 82: 

<?php foreach ($_associatedProducts as $_item): ?>
    <tbody>
        <tr>
            <td data-th="<?php echo $block->escapeHtml(__('Product Name')); ?>" class="col item">
                <strong class="product-item-name"><?php echo $block->escapeHtml($_item->getName()) ?></strong>
                <?php if ($block->getCanShowProductPrice($_product)): ?>

You have to just create block file keep below code in block file,

app/code/Vendor/Extra/Block/Grouped.php file,

<?php
namespace Vendor\Extra\Block;

use Magento\Catalog\Helper\Data;

class Grouped extends \Magento\Framework\View\Element\Template
{
    protected $productRepository;

    public function __construct(        
        \Magento\Framework\View\Element\Template\Context $context,          
        \Magento\CatalogInventory\Model\Stock\StockItemRepository $stockItemRepository,
        array $data = [] 
    ){      
        $this->_stockItemRepository = $stockItemRepository;
        parent::__construct($context,$data);    
    }

    public function getProductQty($id){
        if(is_numeric($id)){           
            $product = $this->_stockItemRepository->get($id);            
            return $product->getQty();
        }else{
            return;
        }
    }

}

app/design/frontend/{Vendor}/{themename}/Magento_GroupedProduct/templates/product/view/type/grouped.phtml

Inside foreach loop in above file,

<?php 
    $blocks = $this->getLayout()->createBlock('Vendor\Extra\Block\Grouped');
    foreach ($_associatedProducts as $_item):
        echo $qtys = $blocks->getProductQty($_item->getId());
    endforeach; 
?>
