Today we discuss how in Magento 2 product collection filters by attribute. We take the example of product collection and filter it by given size. So here is our example.
protected $_productCollectionFactory;
public function __construct(
\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productFactory
) {
$this->_productCollectionFactory = $productFactory;
}
public function getProductCollection()
{
$productCollection = $this->_productCollectionFactory->create();
$productCollection->addAttributeToFilter('size', array('notnull' => true));
return $productCollection;
}
public function __construct(
\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productFactory
) {
$this->_productCollectionFactory = $productFactory;
}
public function getProductCollection()
{
$productCollection = $this->_productCollectionFactory->create();
$productCollection->addAttributeToFilter('size', array('notnull' => true));
return $productCollection;
}
Note: You can sort any collection following this example.
