I am using Magento 2.1, php 7.0.
I am trying to check in block if provided product is in cart. I call from list.phtml (Magento_Catalog template) custom function in overriden block \Magento\Catalog\Block\Product\ListProduct which should check in checkout session that thing:
namespace [vendor]\SkinHelper\Block\Catalog\Product;
use \[vendor]\SkinHelper\Block\Catalog\Product\DownloadableSampleUrlProviderInterface;
use \[vendor]\System\Helper\Debug;
use \Magento\Catalog\Api\CategoryRepositoryInterface;
use \Magento\Catalog\Block\Product\Context;
use \Magento\Catalog\Block\Product\ListProduct as MagentoListProduct;
use \Magento\Catalog\Model\Layer\Resolver;
use \Magento\Checkout\Model\Session;
use \Magento\Downloadable\Model\Product\Type;
use \Magento\Downloadable\Model\ResourceModel\Sample\CollectionFactory;
use \Magento\Framework\Data\Helper\PostHelper;
use \Magento\Framework\Url\Helper\Data;
use \Magento\Framework\UrlInterface;
/** Class 'extends by rewriting' class of block: \Magento\Catalog\Block\Product\ListProduct */
class ListProduct extends MagentoListProduct
implements DownloadableSampleUrlProviderInterface
{
/**
* @var \Magento\Checkout\Model\Session
*/
private $checkoutSession;
/**
* @var \Magento\Downloadable\Model\ResourceModel\Sample\CollectionFactory
*/
private $samplesCollectionFactory;
/**
* @var \Magento\Store\Model\StoreManagerInterface;
*/
private $storeManager;
/**
* @param \Magento\Catalog\Api\CategoryRepositoryInterface $categoryRepository
* @param \Magento\Catalog\Block\Product\Context $context
* @param \Magento\Framework\Data\Helper\PostHelper $postDataHelper
* @param \Magento\Catalog\Model\Layer\Resolver $layerResolver
* @param \Magento\Checkout\Model\Session $checkoutSession
* @param \Magento\Downloadable\Model\ResourceModel\Sample\CollectionFactory $samplesCollectionFactory
* @param \Magento\Framework\Data\Helper\PostHelper $postDataHelper
* @param \Magento\Framework\Url\Helper\Data $urlHelper
* @param array $data
*/
public function __construct(
CategoryRepositoryInterface $categoryRepository,
Context $context,
Resolver $layerResolver,
Session $checkoutSession,
CollectionFactory $samplesCollectionFactory,
PostHelper $postDataHelper,
Data $urlHelper,
array $data
)
{
parent::__construct($context, $postDataHelper, $layerResolver,
$categoryRepository, $urlHelper, $data);
$this->checkoutSession = $checkoutSession;
$this->samplesCollectionFactory = $samplesCollectionFactory;
$this->storeManager = $context->getStoreManager();
}
/**
* Method check if provided product is in cart of current customer.
* Doesn't work dynamically.
*
* @param \Magento\Catalog\Model\Product $product
*
* @return bool $inCart
*/
public function isInCart($product)
{
$productId = $product->getId();
$cartItems = $this->checkoutSession->getQuoteId();
$itemsIds = array();
foreach ($cartItems as $cartItem) {
array_push($itemsIds, $cartItem->getProduct()->getId());
}
return in_array($productId, $itemsIds);
}
Preference works, because I can dump some string like ‘test’ or something. Almost the same code works in controller if fired by entering its url:
$productId = $objectManager->get('Magento\Catalog\Model\Product')->load(6)->getId();
$test = $objectManager->get('\Magento\Checkout\Model\Session')->getQuote();
$result = $test->getAllVisibleItems();
$itemsIds = array();
foreach ($result as $cartItem) {
array_push($itemsIds, $cartItem->getProduct()->getId());
}
print_r(in_array($productId, $itemsIds));
I was debbuging former steps before check - and I am able to grab quote object but it’s almost empty and doesn’t has my product added to cart. And that’s my question - why I am unable to check it inside block?
