Overview of getting product collection in Magento 2

Step 1: Declare in Vendor_ModuleName Block

Step 2: Display product collection in phtml file

Step 1: Declare in Vendor_ModuleName Block

You will use a block class of the module Vendor_ModuleName, then possibly inject the object of \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory in the constructor of the module’s block class.

app/code/Vendor/ModuleName/Block/ProductCollection.php

add code this code

<?php
namespace Vendor\ModuleName\Block;
class ProductCollection 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 getProductCollections()
    {
        $collection = $this->_productCollectionFactory->create();
        $collection->addAttributeToSelect('*');
        $collection->setPageSize(3); // fetching only 3 products
        return $collection;
    }
}
?>

You can request the number of the product collection, that is a limited or unlimited number.

Step 2: Display product collection in phtml file

Print out the product collection in phtml file with the below code:

$productCollection = $block->getProductCollections();
foreach ($productCollection as $product) {
    print_r($product->getData());     
    echo "<br>";
}

Magento 2 get order collection to update customers id using csv.

For example we can take magento 1 we can update using test.php file like that how we can update in magento 2.

I have no idea what you want to tell us here, but I can answer the question:

I am creating new module I am planing to update using controller.But in that how can i get orders collection

Collections are now a mere implementation detail, you work with them using SearchCriteria and Repository objects.

First, inject the OrderRepository and the SearchCriteriaBuilder into your controller, by adding it to the constructor parameters:

public function __construct(
    \Magento\Framework\App\Action\Context $context,
    \Magento\Sales\Api\OrderRepositoryInterface $orderRepository,
    \Magento\Framework\Api\SearchCriteriaBuilder $searchCriteriaBuilder
) {
    $this->orderRepository = $orderRepository;
    $this->searchCriteriaBuilder = $searchCriteriaBuilder;
    parent::__construct(
        $context
    );
}

Then you can use it like this:

$criteria = $this->searchCriteriaBuilder
//  ->addSortOrder(...)
//  ->addFilter(...)
//  ...
    ->create();
$orderResult = $this->orderRepository->getList($criteria);
$orders = $orderResult->getItems();

Magento – Magento2 product collection empty

The authentic and recommended way to fetch product collection is to use API interface

Magento\Catalog\Api\ProductRepositoryInterface

method

getList(\Magento\Framework\Api\SearchCriteriaInterface $searchCriteria)

for this you need to build the search criteria first

Your class should include below classes -

use Magento\Catalog\Api\ProductRepositoryInterface;
use Magento\Framework\Api\SearchCriteriaBuilder;
use Magento\Catalog\Model\Product\Type;
use Magento\Catalog\Model\Product\Visibility;
use Magento\Catalog\Model\Product\Attribute\Source\Status;

Class constructor should be -

/** @var ProductRepositoryInterface  */
protected $productRepository;

/** @var SearchCriteriaBuilder  */
protected $searchCriteriaBuilder;

/** @var Visibility  */
protected $productVisibility;

/** @var Status  */
protected $productStatus;

/**
 * Edit constructor.
 * @param ProductRepositoryInterface $productRepositoryInterface
 * @param SearchCriteriaBuilder $searchCriteriaBuilder
 * @param Visibility $visibility
 * @param Status $status
 */
public function __construct(
    ProductRepositoryInterface $productRepositoryInterface,
    SearchCriteriaBuilder $searchCriteriaBuilder,
    Visibility $visibility,
    Status $status
) {
    $this->productRepository = $productRepositoryInterface;
    $this->searchCriteriaBuilder = $searchCriteriaBuilder;
    $this->productVisibility = $visibility;
    $this->productStatus = $status;
}

Get list method should be -

/**
 * @return array
 */
public function getProductList()
{
    $searchCriteriaBuilder = $this->searchCriteriaBuilder
        ->addFilter('type_id', Type::TYPE_SIMPLE, 'eq')
        ->addFilter('status', $this->productStatus->getVisibleStatusIds(), 'in')
        ->addFilter('visibility', $this->productVisibility->getVisibleInCatalogIds(), 'in')
        ->create();

    $productList = $this->productRepository->getList($searchCriteriaBuilder);
    //echo $productList->getTotalCount();
    $items = $productList->getItems();

    return $items;
}
