I am trying to fetch all categories with filter, but it throws following error :

1 exception(s): Exception #0 (Magento\Framework\Exception\LocalizedException): Invalid method Magento\Catalog\Model\Category\Interceptor::addFieldToFilter

And i have also tried with addFieldToFilter and addAttributeToFilter but still it says invalid method. I want all categories filter with Display mode. Please Help!

Try this solution for the category filter:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$category = $objectManager->create('Magento\Catalog\Model\ResourceModel\Category\Collection');
$category->addAttributeToSelect('*')->addAttributeToFilter('parent_id',['eq'=>3]);
  • Please Avoid using the objectManager concept in the answers, Magento 2 strictly not encourage to use objectManager, of course, we can see some objectManager in core modules, but using objectManager directly is not a good idea. – Anand Ontigeri Mar 14 at 10:36

the class Magento\Catalog\Model\Category is not a collection change your class to:

Magento\Catalog\Model\ResourceModel\Category\CollectionFactory` the solution as follows.


public function __construct(
        Magento\Catalog\Model\ResourceModel\Category\CollectionFactory $collectioFactory
        ){ $this->collectionFactory = $collectioFactory;}

public function yourFunction()
        {
            $this->collection = $this->collectionFactory->create();
            $this->collection->addAttributeToFilter('parent_id',['eq'=>3])
        }
