Overview of getting product collection in Magento 2
While there are different actions to get a certain product collection in Magento 2, they are loading, filtering (e.g. by attributes), and sorting. In this article, I will only introduce the fundamental steps to help you start working with product collection. Here are two initial steps:
- Step 1: Declare in
Mageplaza_HelloWorld
Block - Step 2: Display product collection in
phtml
file
Step 1: Declare in Mageplaza_HelloWorld
Block
You will use a block class of the module Mageplaza_HelloWorld
, then possibly inject the object of \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory
in the constructor of the module’s block class.
app/code/Mageplaza/HelloWorld/Block/HelloWorld.php
<?php
namespace Mageplaza\HelloWorld\Block;
class HelloWorld extends \Magento\Framework\View\Element\Template
{
protected $_productCollectionFactory;
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;
}
}
?>
Note: You can request the number of the product collection, which is a limited or unlimited number. While implementing this function, you will need to extend the code based on the requirement.
Step 2: Display product collection in phtml
file
Print out the product collection in phtml
file with the below code:
$productCollection = $block->getProductCollection();
foreach ($productCollection as $product) {
print_r($product->getData());
echo "<br>";
}
Now, you can get the data of each product in the requested collection.
Hope that you can perform this function easily on your project. If you have any queries about getting product collections by filtering or sorting or any questions in general, use the comment section below!
