Retrieving Quote Data by ID in Magento 2
To access a specific quote in Magento 2 using its ID, you can utilize the CartRepositoryInterface. This approach is straightforward and efficient.
Method 1: Using CartRepositoryInterface
Here's how you can implement it:
<?php
namespace YourNamespace\YourModule\Model;
use Magento\Quote\Api\CartRepositoryInterface;
use Psr\Log\LoggerInterface;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Quote\Api\Data\CartInterface;
class QuoteById
{
private $quoteRepository;
private $logger;
public function __construct(
CartRepositoryInterface $quoteRepository,
LoggerInterface $logger
) {
$this->quoteRepository = $quoteRepository;
$this->logger = $logger;
}
/**
* Retrieve Quote by ID
*
* @param int $quoteId
* @return CartInterface|null
*/
public function getQuoteById(int $quoteId): ?CartInterface
{
try {
return $this->quoteRepository->get($quoteId);
} catch (NoSuchEntityException $e) {
$this->logger->error('Quote not found: ' . $e->getMessage());
return null;
}
}
}
In this code, we inject CartRepositoryInterface and LoggerInterface into the constructor. The getQuoteById method attempts to retrieve the quote by its ID and logs an error if the quote doesn't exist.
Method 2: Using QuoteFactory
Alternatively, you can use QuoteFactory to load the quote. However, be aware that the load method is deprecated in Magento 2. It's recommended to use the repository pattern as shown above. If you choose to use QuoteFactory, here's how:
use Magento\Quote\Model\QuoteFactory;
class QuoteById
{
private $quoteFactory;
public function __construct(QuoteFactory $quoteFactory)
{
$this->quoteFactory = $quoteFactory;
}
public function getQuoteById($quoteId)
{
return $this->quoteFactory->create()->load($quoteId);
}
}
This method creates an instance of the quote and loads it by ID. Due to the deprecation of the load method, it's advisable to use CartRepositoryInterface for future-proofing your code.
Summary
To retrieve quote data by ID in Magento 2, the preferred approach is to use CartRepositoryInterface for its compliance with Magento's best practices. While QuoteFactory is available, its load method is deprecated and not recommended for use in new developments.

namespace Vendor\Module\Model;
use Magento\Quote\Api\CartRepositoryInterface;
use Psr\Log\LoggerInterface;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Quote\Api\Data\CartInterface;
class QuoteById
{

private $logger;
public function __construct(
CartRepositoryInterface $quoteRepository,
LoggerInterface $logger
) {
$this->quoteRepository = $quoteRepository;
$this->logger = $logger;
}
public function getQuoteById(int $quoteId): ?CartInterface
{
try {
return $this->quoteRepository->get($quoteId);
} catch (NoSuchEntityException $e) {
$this->logger->error('Quote not found: ' . $e->getMessage());

}
}
}
How Do I Use This Method to Fetch a Quote?
Call the method by passing a quote ID:
$quoteId = 1; // Replace with the actual quote ID

if ($quote) {
echo "Quote retrieved successfully.";
