Magento 2 - How to get all items in cart?

Question

At checkout page (chekout/cart) I want to edit the checkout button url destination based on cart items (link.phtml).

How can I get all items in cart? I want to do this without using the API. Thanks.

Answer 1

I'll answer the question in two parts:

I. Where should you change the checkout URL?

The destination in link.phtml is $block->getCheckoutUrl(). You should not change the template to change functionality, but change the block Magento\Checkout\Block\Onepage\Link instead. To do so create a plugin for it with a method afterGetCheckoutUrl() to change the return value.

II. How to get all items in the cart?

As of magento-2.0 the service contracts in Magento_Checkout and Magento_Quote do not provide the necessary methods yet, so we use the cart model. In your plugin inject it like this:

public function __construct(\Magento\Checkout\Model\Cart $cart)
{
    $this->cart = $cart;
}

Now that you have access to the cart, you can retrieve the items in several ways, which is basically the same as in Magento 1:

• $this->cart->getQuote()->getItemsCollection()
  

  Returns a quote item collection with all items associated to the current quote.

• $this->cart->getItems()
  

  This is a shortcut for the method above, but if there is no quote it returns an empty array, so you cannot rely on getting a collection instance.

• $this->cart->getQuote()->getAllItems()
  

  Loads the item collection, then returns an array of all items which are not marked as deleted (i.e. have been removed in the current request).

• $this->cart->getQuote()->getAllVisibleItems()
  

  Loads the item collection, then returns an array of all items which are not marked as deleted AND do not have a parent (i.e. you get items for bundled and configurable products but not their associated children). Each array item corresponds to a displayed row in the cart page.

Choose what fits your needs best. In most cases the last method is what you need.

Answer 2

The use of Magento\Checkout\Model\Cart is deprecated.

You should use the session to get the quote and your cart items.

use Magento\Checkout\Model\Session;

public function __construct(
        ...
        Session $session
        ...
    ) {
        ...
        $this->_session = $session;
        ...
    }

public function yourFunction()
{
    $items = $this->_session->getQuote()->getAllVisibleItems();
}

I'm sure that Magento will soon add some kind of repository for session.

As far as I can tell you can't really just get the current quote using using either Magento\Quote\Api\CartRepositoryInterface or Magento\Quote\Api\CartManagementInterface however, if you have the customer ID you can use either of those two to load the quote (which I imagine is the way Magento want you to do it) and from there get quote / cart items.

CartManagementInterface getCartForCustomer($customerId)
CartRepositoryInterface getForCustomer($customerId)

Answer 3

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$cart = $objectManager->get('\Magento\Checkout\Model\Cart'); 

// retrieve quote items collection
$itemsCollection = $cart->getQuote()->getItemsCollection();

// get array of all items what can be display directly
$itemsVisible = $cart->getQuote()->getAllVisibleItems();

// retrieve quote items array
$items = $cart->getQuote()->getAllItems();

foreach($items as $item) {
    echo 'ID: '.$item->getProductId().'<br />';
    echo 'Name: '.$item->getName().'<br />';
    echo 'Sku: '.$item->getSku().'<br />';
    echo 'Quantity: '.$item->getQty().'<br />';
    echo 'Price: '.$item->getPrice().'<br />';
    echo "<br />";
}

Like @Frank says

Magento\Checkout\Model\Cart

was deprecated in version 100.1.0

Another option is to use a Proxy and benefit from the performance optimization

Here is how:

public function __construct(Magento\Checkout\Model\Session\Proxy $cartSession)
{
    $this->cartSession = $cartSession;
}

then retrieve the items:

$this->cartSession->getQuote()->getItems()

Answer 5

This code is functional for Magento 2.4.3

public function __construct(
    \Magento\Checkout\Model\Session $session
) {
     $this->checkoutSession = $session;
 }

public function yourFunction()
{
    $items = $this->checkoutSession->getQuote()->getAllVisibleItems();
    $cartItems = [];
    foreach($items as $item) {
      $cartItems[] = [
       'name' => $item->getName(),
       'sku' => $item->getSku(),
       ];
   }
   return $cartItems;
}
