Magento2所有子類別的產品數量和最低價格

Question

我需要獲得父類別的產品數量和最低價格（計數和最低價格應從其所有子類別中計算）。我用下面的代碼

$categoryHelper = $this->helper('Magento\Catalog\Helper\Category'); 
$objectManager = \Magento\Framework\App\ObjectManager::getInstance(); 
foreach($categoryHelper->getStoreCategories() as $category): 
$category = $objectManager->create('Magento\Catalog\Model\Category')->load($category->getId()); 
    $_outputhelper = $this->helper('Magento\Catalog\Helper\Output');     
    $products = $category->getProductCollection()->addAttributeToSelect('*')->setOrder('price','ASC')->setPageSize(1); 
    $fromprice = 0; 
    foreach($products as $product){ 
     $fromprice = $product->getPrice(); 
    } 

    $count = $category->getProductCount(); 
endforeach; 

但上面的代碼給產品數量和僅父類別的最低價格。任何人都可以幫助，以便代碼從子類別中計算出來嗎？

也getProductCount（）給出錯誤的結果。它甚至包括所有的產品會禁用產品

感謝

嘗試對當前類別，以獲得子類別：

$subcategory = $category->getChildrenCategories(); 

foreach($subcategory as $subcat) { 
    echo $subcat->getName(); 
}
