Magento 2 – How To Get Product Collection?

Today we will learn very interesting things. which is getting product collection with two ways, Let’s see how they work.

With Dependency Injection:

We will get the list of products in our Magento 2 store using Dependency Injection. First, we need to inject the object of \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory class in the constructor of your module’s block class and then access it from template file “.phtml“.
Sample file path you will use is app/code/Webiators/CustomChanges/Block/Product.php

&lt;?php
namespace Webiators\CustomChanges\Block;


class Product extends \Magento\Framework\View\Element\Template
{ 
    protected $_productCollectionFactory;
  
    protected $_productVisibility;
  
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context, 
        \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,
        \Magento\Catalog\Model\Product\Visibility $productVisibility,
        array $data = &#91;]
    ) {
        $this->_productCollectionFactory = $productCollectionFactory; 
        $this->_productVisibility = $productVisibility; 
        parent::__construct($context, $data);
    }
  
    public function getProductCollection() {
        $collection = $this->_productCollectionFactory->create();
        $collection->addAttributeToSelect('*');
  
        // filter current website products
        $collection->addWebsiteFilter();
 
        // filter current store products
        $collection->addStoreFilter();
  
        // set visibility filter
        $collection->setVisibility($this->productVisibility->getVisibleInSiteIds());
  
        // fetching 10 products (we can pass number of products)
        $collection->setPageSize(10); 
  
        return $collection;
    }
}

<?php

namespace Webiators\CustomChanges\Block;

class Product extends \Magento\Framework\View\Element\Template

{

protected $_productCollectionFactory;

protected $_productVisibility;

public function __construct(

\Magento\Framework\View\Element\Template\Context $context,

\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,

\Magento\Catalog\Model\Product\Visibility $productVisibility,

array $data = []

) {

$this->_productCollectionFactory = $productCollectionFactory;

$this->_productVisibility = $productVisibility;

parent::__construct($context, $data);

}

public function getProductCollection() {

$collection = $this->_productCollectionFactory->create();

$collection->addAttributeToSelect('*');

// filter current website products

$collection->addWebsiteFilter();

// filter current store products

$collection->addStoreFilter();

// set visibility filter

$collection->setVisibility($this->productVisibility->getVisibleInSiteIds());

// fetching 10 products (we can pass number of products)

$collection->setPageSize(10);

return $collection;

}

Now, we will create PHTML file and call Block functions. let’s take a look

$productCollection = $block->getProductCollection(); 
foreach ($productCollection as $product) { 
    echo $product->getId() . '&lt;br />';
    echo $product->getName() . '&lt;br />';
    echo $product->getPrice() . '&lt;br />';
}

$productCollection = $block->getProductCollection();

foreach ($productCollection as $product) {

echo $product->getId() . ' ';

echo $product->getName() . ' ';

echo $product->getPrice() . ' ';

}

With Object Manager:

Now, let’s see how can we call Product collection with Object Manager method.


$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
  
$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$collection = $productCollectionFactory->create();
$collection->addAttributeToSelect('*');
 
// filter current website products
$collection->addWebsiteFilter();
 
// filter current store products
$collection->addStoreFilter();
 
// set visibility filter
$collection->setVisibility($objectManager->get('\Magento\Catalog\Model\Product\Visibility')->getVisibleInSiteIds());
 
// fetching 10 products (we can pass number of products)
$collection->setPageSize(10);
    foreach ($productCollection as $product) { 
    echo $product->getId() . '&lt;br />';
    echo $product->getName() . '&lt;br />';
    echo $product->getPrice() . '&lt;br />';
}

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');

$collection = $productCollectionFactory->create();
