Sometimes you need to clear the cart when certain conditions. For example, when a customer adds a specific product, you want to remove all items from the cart. Or you may need to clear the cart when a customer applies a particular coupon code, Or you might need to remove a specific item from the cart.
There are several ways to clear the cart in Magento 2 programmatically.
We can discuss that in detail here.
app/code/Elightwalk/Extension/Controller/EmptyCart/Index.php
<?php
namespace Elightwalk\Extension\Controller\EmptyCart;
use Magento\Framework\App\Action\Action;
class Index extends Action
{
protected $modelCart;
protected $checkoutSession;
public function __construct(
\Magento\Framework\App\Action\Context $context
\Magento\Checkout\Model\Session $checkoutSession,
\Magento\Checkout\Model\Cart $checkoutCart
){
parent::__construct($context);
$this->checkoutSession = $checkoutSession;
$this->checkoutCart = $checkoutCart;
}
public function execute() {
$cart = $this->checkoutCart;
$items = $this->checkoutSession->getQuote()->getItemsCollection();
foreach($items as $item) {
$cart->removeItem($item->getId())->save();
}
}
}
?>
In this method, sometimes a cache issue comes once a redirect to the checkout page. For example, after clearing the cart programmatically, you must add new items and then redirect to Magento checkout. The total item count will have an issue.
app/code/Elightwalk/Extension/Controller/EmptyCart/Index.php
<?php
namespace Elightwalk\Extension\Controller\EmptyCart;
use Magento\Framework\App\Action\Action;
class Index extends Action
{
protected $quoteItemFactory;
protected $checkoutSession;
public function __construct(
\Magento\Framework\App\Action\Context $context,
\Magento\Checkout\Model\Session $checkoutSession,
\Magento\Quote\Model\Quote\ItemFactory $quoteItemFactory
) {
parent::__construct($context);
$this->checkoutSession = $checkoutSession;
$this->quoteItemFactory = $quoteItemFactory;
}
public function execute() {
$items = $this->checkoutSession->getQuote()->getItemsCollection();
foreach($items as $item) {
$_item = $this->quoteItemFactory->create()->load($item->getId());
$_item->delete();
}
}
}
?>
In this method, you also face the same issue of cache, as explained above, when you redirect to the cart of checkout pages. If there is no need for a redirect and you only need to delete some items from the cart programmatically, then it will be good to go and use.
app/code/Elightwalk/Extension/Controller/EmptyCart/Index.php
<?php
namespace Elightwalk\Extension\Controller\EmptyCart;
use Magento\Framework\App\Action\Action;
class Index extends Action
{
protected $checkoutCart;
public function __construct(
\Magento\Framework\App\Action\Context $context,
\Magento\Checkout\Model\Cart $checkoutCart
) {
parent::__construct($context);
$this->checkoutCart = $checkoutCart;
}
public function execute() {
$this->checkoutCart->truncate();
}
}
The above is recommended method to try while deleting all items from the cart programmatically, and you add new items and redirect to any pages. The cache issue will not come in the role here, and the output will be as expected; there is a con that it will remove all items from the cart.
The above method has the benefit that it will keep the same quote id.
As explained above, several methods exist to delete the items from the cart programmatically, so choose the way as per your requirement and archive the goal in minimal time.
