Magento2所有子类别的产品数量和最低价格

Question

我需要获得父类别的产品数量和最低价格（计数和最低价格应从其所有子类别中计算）。我用下面的代码

$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; 

但上面的代码给产品数量和仅父类别的最低价格。任何人都可以帮助，以便代码从子类别中计算出来吗？

也getProductCount（）给出错误的结果。它甚至包括所有的产品会禁用产品

感谢

尝试对当前类别，以获得子类别：

$subcategory = $category->getChildrenCategories(); 

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