Magento 2 get product attribute value without objectManager

Question

I load some related products inside a foreach and want to call some attribute values of these individual products.

My current code below works fine with using $objectManager, but that's not the best way to handle this.

How can I get the value of the product attribute, without using the $objectManager ?

Code Helper/Data:

<?php
namespace MyModule\LinkedProducts\Helper;

class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
    public function __construct(
        \MagePal\LinkProduct\Model\Accessory $accessory,
        \Magento\Catalog\Block\Product\AbstractProduct $abstractProduct
    ) {
        $this->accessory = $accessory;
        $this->abstractProduct = $abstractProduct;
    }

    public function getLinkedProducts()
    {
    $product = $this->abstractProduct->getProduct();    
    return $this->accessory->getAccessoryProducts($product);
    }

}

Code phtml:

<?php $linkedproducts = $this->helper('MyModule\LinkedProducts\Helper\Data');
$relatedProducts = $linkedproducts->getLinkedProducts();?>

<?php foreach ($relatedProducts as $relatedProduct) {

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$_product = $objectManager->create('Magento\Catalog\Model\Product')->load($relatedProduct->getId());
echo $_product->getData('my_attribute_value');
}?>

Answer 1

You can add one more function in your helper class to load product info and call same function in PHTML.

Updated code will be like as below:

<?php
namespace MyModule\LinkedProducts\Helper;

class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
public function __construct(
    \MagePal\LinkProduct\Model\Accessory $accessory,
    \Magento\Catalog\Block\Product\AbstractProduct $abstractProduct,
    \Magento\Catalog\Model\ProductFactory $productFactory
) {
    $this->accessory = $accessory;
    $this->abstractProduct = $abstractProduct;
    $this->productFactory = $productFactory;
}

public function getLinkedProducts()
{
    $product = $this->abstractProduct->getProduct();    
    return $this->accessory->getAccessoryProducts($product);
}

public function getProductInfo($productId)
{
    $_product = $this->productFactory->create()->load($productId);
    return $_product;
}    

}

PHTML Code:

<?php 
$linkedproducts = $this->helper('MyModule\LinkedProducts\Helper\Data');
$relatedProducts = $linkedproducts->getLinkedProducts();?>

<?php 
    foreach ($relatedProducts as $relatedProduct) {

        $_product = $linkedproducts->getProductInfo($relatedProduct->getId());
        echo $_product->getData('my_attribute_value');
    }
?>

Answer 2

You can do this by add new function in your helper and call in phtml.

Helper File :

<?php
namespace MyModule\LinkedProducts\Helper;

class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
    private $accessory;
    private $abstractProduct;
    private $productFactory;
    public function __construct(
        \MagePal\LinkProduct\Model\Accessory $accessory,
        \Magento\Catalog\Block\Product\AbstractProduct $abstractProduct,
        \Magento\Catalog\Model\ProductFactory $productFactory
    ) {
        $this->accessory = $accessory;
        $this->abstractProduct = $abstractProduct;
        $this->productFactory = $productFactory;
    }

    public function getLinkedProducts()
    {
        $product = $this->abstractProduct->getProduct();    
        return $this->accessory->getAccessoryProducts($product);
    }

    public function getAttributeInfo($productId = null)
    {
        if($productId){
            $productObj = $this->productFactory->create()->load($productId);
            return $productObj->getData('my_attribute_value');
        }
        return '';
    }

}

Phtml file :

<?php

$linkedproducts = $this->helper('MyModule\LinkedProducts\Helper\Data');
$relatedProducts = $linkedproducts->getLinkedProducts();

foreach ($relatedProducts as $relatedProduct) {
    echo $linkedproducts->getAttributeInfo($relatedProduct->getId());
}
?>

Remove generated and clean cache.
