Magento 2 : How to load quote by quote id

Question

How can I load quote in magento 2 by quote id ?

Answer 1

you can inject in your class an instance of \Magento\Quote\Model\QuoteFactory.

protected $quoteFactory;

public function __construct(
    ...
    \Magento\Quote\Model\QuoteFactory $quoteFactory,
    ....
) {
    ....
    $this->quoteFactory = $quoteFactory;
    ....
}

Then you can use:

$quote = $this->quoteFactory->create()->load($quoteId);

This should work for now, but soon, the load method is going to go away and you need to use a service contract.
So you can use \Magento\Quote\Api\CartRepositoryInterface.
Same as above, inject an instance of this class in your class:

protected $quoteRepository;

public function __construct(
    ...
    \Magento\Quote\Api\CartRepositoryInterface $quoteRepository,
    ....
) {
    ....
    $this->quoteRepository = $quoteRepository;
    ....
}

and use this:

$this->quoteRepository->get($quoteId);

If you want to see how the code looks like, the implementation for \Magento\Quote\Api\CartRepositoryInterface is \Magento\Quote\Model\QuoteRepository

Answer 2

First you need to inject a \Magento\Quote\Model\QuoteFactory in your class constructor:

protected $_quoteFactory;

public function __construct(
    ...
    \Magento\Quote\Model\QuoteFactory $quoteFactory
) {
    $this->_quoteFactory = $quoteFactory;
    parent::__construct(...);
}

Then in your class you can do:

$this->_quoteFactory->create()->loadByIdWithoutStore($quoteId);

On a side note you can also use the following methods to load a quote:

• loadActive($quoteId) where it loads corresponding active quote (where is_active = 1)
• loadByCustomerId($customerId) where it load the active quote corresponding to the customer id.

NB: you can also use the object manager directly to do it but it is not recommended:

$this->_objectManager->create('Magento\Quote\Model\Quote')->loadByIdWithoutStore($quoteId);

Answer 3

I recommend the following method

use Psr\Log\LoggerInterface;
use Magento\Quote\Api\CartRepositoryInterface;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Quote\Api\Data\CartInterface;

class MyClass
{
    /**
     * @var CartRepositoryInterface
     */
    public $quoteRepository;

    /**
     * @var LoggerInterface
     */
    public $logger;
        public function __construct(
        CartRepositoryInterface $quoteRepository,
        LoggerInterface $logger
    ) {
        $this->quoteRepository = $quoteRepository;
        $this->logger = $logger;
    }

    /**
     * Get Quote By Id    
     * @param int $quoteId
     * @return CartInterface|null
     */
    public function getQuoteById(int $quoteId): ?CartInterface
    {
        $quote = null;
        try {
            $quote = $this->quoteRepository->get($quoteId);
        } catch (NoSuchEntityException $e) {
            $this->logger->error(
                'Quote does not exist'.,
                [$e->getMessage()]
            );
        }
        return $quote;
    }
}
