product collection

hello,

using magento 2.2.1. Trying to get product collection, I'm doing this:

 

<?php
namespace Hoop\Util\Block;
class CategoryCollect extends \Magento\Framework\View\Element\Template
{
    protected $_categoryHelper;
    protected $categoryFlatConfig;
    protected $topMenu;
    protected $_productCollectionFactory;

    /**
     * @param \Magento\Framework\View\Element\Template\Context $context
     * @param \Magento\Catalog\Helper\Category $categoryHelper
     * @param array $data
     */
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context,
        \Magento\Catalog\Helper\Category $categoryHelper,
        \Magento\Catalog\Model\Indexer\Category\Flat\State $categoryFlatState,
        \Magento\Theme\Block\Html\Topmenu $topMenu,
        \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory
    )
    {
        $this->_categoryHelper = $categoryHelper;
        $this->categoryFlatConfig = $categoryFlatState;
        $this->topMenu = $topMenu;
        $this->_productCollectionFactory = $productCollectionFactory;

        $collection = $this->_productCollectionFactory->create();
        $collection->addAttributeToSelect('*');
        // $collection->setPageSize(3);
        var_dump($collection->getSize());
        parent::__construct($context);
    }

but the getSize() returns always 0, but I have 16 products in admin.

What am I doing wrong?

thanks a lot

Re: product collection

Hello,

thanks for your answer. Unfortunately also count() returns 0.

Any further hint?

 

Thanks

Re: product collection

Your constructor object is working fine for me, I have check in one my extension and all product count display perfect.

 

public function __construct(
    \Magento\Framework\View\Element\Template\Context $context,
    \Magento\Catalog\Helper\Category $categoryHelper,
    \Magento\Catalog\Model\Indexer\Category\Flat\State $categoryFlatState,
    \Magento\Theme\Block\Html\Topmenu $topMenu,
    \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory
)
{
    $this->_categoryHelper = $categoryHelper;
    $this->categoryFlatConfig = $categoryFlatState;
    $this->topMenu = $topMenu;
    $this->_productCollectionFactory = $productCollectionFactory;

    $collection = $this->_productCollectionFactory->create();
    $collection->addAttributeToSelect('*');
    var_dump($collection->getSize());
    parent::__construct($context);
}

Might be you have to check your all product is available and all of the product is enable.

Please do using reindex command might be indexing cause the count as 0 so you need to check using indexing and get perfect product count for your code.

So you havent problem with code.
