It looks like you're trying to create an EAV attribute in Magento 2. The error about undefined classes suggests that the classes
Magento\Eav\Model\Entity\AttributeFactory and Magento\Eav\Model\Entity\Attribute\SetFactory are not being correctly injected.
You have to declare them.
below is the basic code of how You can use it to create the attribute.
<?php
use Magento\Eav\Api\AttributeRepositoryInterface;
use Magento\Eav\Model\Entity\AttributeFactory;
use Magento\Framework\App\ResourceConnection;
class YourClass
{
protected $attributeRepository;
protected $attributeFactory;
protected $resourceConnection;
public function __construct(
AttributeRepositoryInterface $attributeRepository,
AttributeFactory $attributeFactory,
ResourceConnection $resourceConnection
) {
$this->attributeRepository = $attributeRepository;
$this->attributeFactory = $attributeFactory;
$this->resourceConnection = $resourceConnection;
}
public function createAttribute(array $data)
{
$attribute = $this->attributeFactory->create();
$attribute->setAttributeCode($data['code']);
$attribute->setEntityTypeId($data['entity_type_id']);
$attribute->setFrontendInput($data['input_type']);
$attribute->setDefaultFrontendLabel($data['label']);
$attribute->setIsUserDefined($data['is_user_defined']);
$attribute->setIsRequired($data['is_required']);
$attribute->setBackendType('varchar');
$this->attributeRepository->save($attribute);
}
