Recently while working on one of customers store, we came across the requirement of clearing shopping cart programmatically. Well, it is possible to clear the cart using three different ways which are mentioned below. Working with Magento several times you came across such a situation that’s why we thought of creating an article on Magecomp blog.

1. First method :
Create “Clearcart.php” file using following code at below location inside your custom extension folder.
app\code\vendor\extension\Controller\Index\Clearcart.php

namespace Vendor\Extension\Controller\Index;
use Magento\Checkout\Model\Cart;
use Magento\Checkout\Model\Session as CheckoutSession;
use Magento\Framework\App\Action\Action;
class Clearcart extends Action
{
 protected  $_modelCart;
 protected $ checkoutSession;
 public function __construct(CheckoutSession $checkoutSession,Cart $modelCart)
        {
         $this->checkoutSession = $checkoutSession;
         $this->_modelCart = $modelCart;
        }
 public function execute()
        {
  $cart = $this->_modelCart;
  $quoteItems = $this->checkoutSession->getQuote()->getItemsCollection();
  foreach($quoteItems as $item)
  {
   $cart->removeItem($item->getId())->save(); 
  }
 }
}

2. Second Method :
In this method, we can get the current cart using model cart object and then simply truncate it.

namespace Vendor\Extension\Controller\Index;
class Clearcart extends Action
{
 public function execute()
 {
  $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
  $cartObject = $objectManager->create('Magento\Checkout\Model\Cart')->truncate(); 
   $cartObject->saveQuote();
 }
}

3. Third Method :
In this last method, we can delete item from cart Modal using below code.

namespace Vendor\Extension\Controller\Index;
use Magento\Checkout\Model\Session as CheckoutSession;
use Magento\Quote\Model\Quote\Item
 
class Clearcart extends Action
{
 protected  $modelCartItem;
 protected $checkoutSession;

 public function __construct(CheckoutSession $checkoutSession,Item $modelCartItem)
        {
         $this->checkoutSession = $checkoutSession;
                $this->_ modelCartItem = $modelCartItem;
        }

 public function execute()
 {
      $checkoutSession = $this->getCheckoutSession();
  $allItems = $checkoutSession->getQuote()->getAllVisibleItems();
  foreach ($allItems as $item) 
  {
       $cartItemId = $item->getItemId();
          $itemObj=$this->getItemModel()->load($cartItemId);
          $itemObj->delete();
  }
   }
}

From give three methods, you can pick any one according to your need and choice.
