Authentic way to access quote for admin and frontend area

Question

I am working on shipping module where i need to fetch quote subtotal in both area frontend as well as admin order create.

I am using Magento\Checkout\Model\Session to get the quote subtotal but when i try to check in admin no value return for quote.

Also tried Magento\Quote\Model\Quote method getBaseSubTotal return nothing.

Any other solution where we can use same code for both area.

Answer 1

In General, Checkout Session is not initiated for adminhtml area so it won't be possible without customization.

In My opinion, you should set some value in quote table when quote is created or initiated every time and that is similar for adminhtml and frontend area.

For example. save IP address in quote cart is created is create and fetch Quote by current IP match with Quote IP and it will work from admin too.

Hope this approach works!!!

1. For Admin quote session Magento\Backend\Model\Session\Quote class is responsible for getting backend quote order processes

2. For Frontend :

You can get by Factory method

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

// create a quote object

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

OR You can get by Repository method

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

//    get a quote object by its id

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

You can use the Magento\Quote\Model\QuoteRepository class to get the quote subtotal in both the front and backend. This class is used to retrieve quotes from the database and will have the quote subtotal included.

You can call this class in the front end using the \Magento\Framework\App\ObjectManager.

In the backend, you can call it using the Magento\Quote\Model\QuoteRepositoryFactory.

Example:

//Frontend 
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$quoteRepository = $objectManager->create('Magento\Quote\Model\QuoteRepository');
$quote = $quoteRepository->get($quoteId);
$subtotal = $quote->getBaseSubtotal();

//Backend 
$quoteRepositoryFactory = $this->_objectManager->create('Magento\Quote\Model\QuoteRepositoryFactory');
$quoteRepository = $quoteRepositoryFactory->create();
$quote = $quoteRepository->get($quoteId);
$subtotal = $quote->getBaseSubtotal();
