Magento 2 Get product collection in a custom template block

Question

I have defined a featured product template in a cms static page as below:

{{block class="Magento\Catalog\Block\Product\ListProduct" template="Magento_Catalog::product/featured.phtml"}}

Now I want to load original product collection(without any filters applied, which I am gonna apply later) inside my template "featured.phtml", but I can't find a way to do it directly without creating a module for such a tiny task.

Somebody let me know, how to do something like below in Magento2, in this case: Mage::getModel('catalog/product')->getCollection()

Answer 1

It is better to create custom block for your needs. It is not clear why you can create custom template, but not block. Also have you considered using \Magento\Catalog\Api\ProductRepositoryInterface::getList which is part of Magento public API? Collection should not be manipulated directly.

Implementation below is a hack (object manager should never be used directly), but the only solution without creation of a new block:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
/** @var \Magento\Catalog\Model\ResourceModel\Product\Collection $productCollection */
$productCollection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\Collection');
/** Apply filters here */
$productCollection->load();

Answer 2

Instead of using the Object manager u can try:

public function __construct(
    \Magento\Backend\Block\Template\Context $context,        
    \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,        
    array $data = []
)
{    
    $this->_productCollectionFactory = $productCollectionFactory;    
    parent::__construct($context, $data);
}

 public function getProductCollection()
{
    $collection = $this->_productCollectionFactory->create();
    $collection->addAttributeToSelect('*');
    $collection->setPageSize(3); // fetching only 3 products
    return $collection;
}

Answer 3

In your block file:

use Magento\Catalog\Model\ProductFactory;
use Magento\Framework\View\Element\Template\Context;

protected $_productFactory;

public function __construct(
   Context $context, 
   ProductFactory $productFactory,
   array $data = array()       
) {
   $this->_productFactory   = $productFactory;
   parent::__construct($context, $data);
}

public function getProductCollection() {
   $productCollection = $this->_productFactory->create()->getCollection();
   return $productCollection;
}

To get the collection call getProductCollection function.

Try this :

    protected $_productCollectionFactory;

    public function __construct(
        \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,
        array $data = []
    ) {
        $this->_productCollectionFactory = $productCollectionFactory;
        parent::__construct($data);
    }



    public function getProductCollection()
    {
        /** @var $collection \Magento\Catalog\Model\ResourceModel\Product\Collection */
        $collection = $this->_productCollectionFactory->create();
        return $collection;
    }
