Get shopping cart details in Magento2 - magento2

Question

I know in Magento 1 you can get the shopping cart details on any page with:
$cart = Mage::getModel('checkout/cart')->getQuote();
foreach ($cart->getAllItems() as $item) {
$productId = $item->getProduct()->getId();
$productPrice = $item->getProduct()->getPrice();
}
How do I do the same thing in Magento 2?

Answer 1

protected $_checkoutSession;
public function __construct (
\Magento\Checkout\Model\Session $_checkoutSession
) {
$this->_checkoutSession = $_checkoutSession;
}
public function execute(\Magento\Framework\Event\Observer $observer)
{
$cartData = $this->_checkoutSession->getQuote()->getAllVisibleItems();
$cartDataCount = count( $cartData );
}
you can get the quote data in observer

Answer 2

I figured this out by myself in the end:
<?php
$om = \Magento\Framework\App\ObjectManager::getInstance();
$cartData = $om->create('Magento\Checkout\Model\Cart')->getQuote()->getAllVisibleItems();
$cartDataCount = count( $cartData );
?>
<div class="bagDrop" id="bagDrop">
<h4>Quote Basket</h4>
<?php if( $cartDataCount > 1 ): ?>
<?php endif; ?>
<div class="bagDropWindow">
<?php if( $cartDataCount > 0 ): ?>
<div class="bagDropList" id="bagDropList">
<?php foreach( $cartData as $item ): ?>
<?php $product = $item->getProduct(); ?>
<?php $image = $product['small_image'] == '' ? '/pub/static/frontend/Clear/usb2u/en_GB/images/default-category-image_1.png' : '/pub/media/catalog/product' . $product['small_image']; ?>
<a href="<?php echo $product['request_path']; ?>" class="bagDropListItem">
<img src="<?php echo $image; ?>">
<p>
<span class="name"><?php echo $product['name']; ?></span><br>
<span class="qty">x <?php echo $item->getQty(); ?></span>
</p>
</a>
<?php endforeach; ?>
</div>
<?php else: ?>
<div class="emptyList">No products in your basket.</div>
<?php endif; ?>
</div>
<?php if( $cartDataCount > 1 ): ?>
<?php endif; ?>
</div>

Get Product Details in Checkout Page
<?php
namespace namespace\modulename\Block\xxx;
class xxx extends \Magento\Framework\View\Element\Template {
public function __construct(
\Magento\Checkout\Model\Cart $cart,
\namespace\modulename\Model\CrossSellFactory $crosssell,
\Magento\Framework\View\Element\Template\Context $context,
\Magento\Customer\Model\Session $customerSession,
\Magento\Framework\ObjectManagerInterface $objectManager,
array $data = []
) {
parent::__construct($context, $data);
$this->cart = $cart;
$this->_crosssell = $crosssell;
$this->customerSession = $customerSession;
$this->_objectManager = $objectManager;
}
public function getProductIds()
{
$productInfo = $this->cart->getQuote()->getItemsCollection();
foreach ($productInfo as $item) {
$item[] = $item->getProductId();
echo"<pre>";print_r($item->getProductId());
}
return $item;
}
}
Put the above .php file in your block and return the value in phtml file like i shown below.
<?php
$Productdetails = $block->getProductIds();
echo"<pre>";print_r($Productdetails->getName());
?>

You can easily get the shopping cart details in the Magento 2 by implementing the below-mentioned code:
<?php
$object = \Magento\Framework\App\ObjectManager::getInstance();
$cart = $object->create('Magento\Checkout\Model\Cart')->getQuote()->getAllVisibleItems();
$cartCount = count( $cart );
if($cartCount > 0){
echo $cartCount;
} else{
echo "0" ;
}
?>

Usage examples:
\Magento\Checkout\Block\Cart\AbstractCart::getQuote():
/**
* Get active quote
*
* #return Quote
*/
public function getQuote()
{
if (null === $this->_quote) {
$this->_quote = $this->_checkoutSession->getQuote();
}
return $this->_quote;
}
\Magento\Checkout\Block\Cart\Totals::getQuote():
/**
* Get active or custom quote
*
* #return \Magento\Quote\Model\Quote
*/
public function getQuote()
{
if ($this->getCustomQuote()) {
return $this->getCustomQuote();
}
if (null === $this->_quote) {
$this->_quote = $this->_checkoutSession->getQuote();
}
return $this->_quote;
}
\Magento\Checkout\Helper\Cart::getQuote():
/**
* Retrieve current quote instance
*
* #return \Magento\Quote\Model\Quote

return $this->_checkoutSession->getQuote();
}
