Magento 2 get all product attributes without product id

Question

I want to retrieve all product attributes those are available, then convert it to name & value for my select options field. In Magento 1 I can achieve it like this:

public function getMagentoAttributes()
{
 $values[] = array(
 'value' => '',
 'label' => 'Pick Product Attribute'
 );
 $categories = Mage::getResourceModel('catalog/product_attribute_collection')->getItems();
 foreach ($categories as $category) {
 if ($category->getFrontendLabel() != '') {
 $label = $category->getFrontendLabel();
 } else {
 $label = $category->getAttributecode();
 }
 $values[] = array(
 'value' => $category->getAttributecode(),
 'label' => $label
 );
 }
 return $values;
}

Is there a way in magento 2 to do the same thing?

• Gurjeet Singh: I have used code according to "RonakChauhan" it is working fine in my block file But I am facing some issue i need help in that I am unable to filter attributes according to their visibility i.e I need the attributes whose status is set "visible => yes" in Admin...Any Help will be Appreciated... Here is my Code for getting Product Attribute's collection class ProductList extends \Magento\Framework\View\Element\Template{ protected $_attributeFactory; public function __construct( \Magento\Catalog\Model\ResourceModel\Eav\Attribute $attributeFactory ){ parent::__construct($context); $this->_attrib

Answer 1

protected $_attributeFactory;
 public function __construct(
 ....
 \Magento\Catalog\Model\ResourceModel\Eav\Attribute $attributeFactory,
 ....
) {
 ....
 $this->_attributeFactory = $attributeFactory;
 ....
}
public function <func_name>()
{
 $attributeInfo = $this->_attributeFactory->getCollection();
 foreach($attributeInfo as $attributes)
 {
 $attributeId = $attributes->getAttributeId();
 // You can get all fields of attribute here
 }
}

Here you can have whole collection of attributes, you can filter it as per your need.

• simple guy: how to get the attribute name and id?
• Ronak Chauhan: using foreach you can get getAttributeId() as well as getAttributeName()
• Ronak Chauhan: Check updated answer
• simple guy: getAttributeName print blank
• Ronak Chauhan: echo "<pre>"; print_r($attributes);exit; use this in foreach and check

Answer 2

Another idea is that we should try with Service Contracts Layer.

Use Magento\Eav\Api\AttributeRepositoryInterface to get the eav attribute.

I have an answer already here: https://magento.stackexchange.com/a/161426/33057

For example:

 $searchCriteria = $this->searchCriteriaBuilder->create();
 $attributeRepository = $this->attributeRepository->getList(
 'catalog_product',
 $searchCriteria
 );
 foreach ($attributeRepository->getItems() as $items) {
 $items->getAttributeCode();
 $items->getFrontendLabel();
 }

NOTE: For the entity type code in getList method, we can find in the eav_entity_type table.

• VishalParkash: What is 'catalog_product' as an argument in getList()??
• Maikel Koek: This should be the accepted answer!
