How to get the list of attributes on frontend in Magento 2 [duplicate]

Question

I'm using Magento 2, when I try add product in Backend, in the Configurations tab, I have created Configuration and I saw there three attributes.

How can I get them in a module on frontend?

I see they are stored in eav_attribute table but I dont know which SQL can be do it, because it has no conditional column

Thank so much!

Answer 1

based on this answer , you can get all the attributes and then filter it using the entity_type_id

public function __construct(
    \Magento\Framework\Api\SearchCriteriaBuilder $searchCriteriaBuilder,
    \Magento\Eav\Api\AttributeRepositoryInterface $attributeRepository,
    ......
)
{
    $this->searchCriteriaBuilder = $searchCriteriaBuilder;
    $this->attributeRepository = $attributeRepository;
    ......
}


public function execute(){
    $searchCriteria = $this->searchCriteriaBuilder->create();
    $attributeRepository = $this->attributeRepository->getList(
        'catalog_product',
        $searchCriteria
    );

    foreach ($attributeRepository->getItems() as $items) {
        $items->getAttributeCode();
        $items->getFrontendLabel();
    }
}

Answer 2

You can use this,

namespace NameSpace\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{    
protected $_productRepository;

public function __construct(
    \Magento\Backend\Block\Template\Context $context,        
    \Magento\Catalog\Model\ProductRepository $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);
}
}

and in your phtml.

$id = YOUR_PRODUCT_ID;
$product = $block->getProductById($id); // load product bi ID
$attributes = $product->getAttributes();
foreach ($attributes as $attribute) { 
   echo $attribute->getAttributeCode(); echo '<br />';
   echo $attribute->getStoreLabel(); echo '<br />';
   echo $attribute->getFrontendLabel(); echo '<br />';    
   echo $attribute->getFrontend()->getLabel(); echo '<br />';

// you might not get value for all attributes
   echo $attribute->getFrontend()->getValue($product); echo '<br />';    
}
