Magento：在类别中显示新产品

我找不到解决问题的方法： 我有一个由我创建的带有layout.phtml的类别。 在这个类别中，我只想显示这个类别的新产品（由new from date和new to date字段设置）。 我不明白怎么做（不管是xml还是php）。

---

有人能帮我吗？

请尝试此操作，以按类别ID筛选所有新产品-

public function getProductCollection($catIds) {
$productIds = $this->getProductIdsByCategories($catIds);
$todayDate  = Mage::app()->getLocale()->date()->toString(Varien_Date::DATETIME_INTERNAL_FORMAT);
    $storeId    = Mage::app()->getStore()->getId();
    $collection = Mage::getResourceModel('catalog/product_collection')
                        ->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes())
                        ->setStoreId($storeId)
                        ->addStoreFilter($storeId)
                        ->addMinimalPrice()
                        ->addTaxPercents()
                        ;
    Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($collection);
    Mage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($collection);

    $collection
        ->addAttributeToFilter('news_from_date', array('date' => true, 'to' => $todayDate))
        ->addAttributeToFilter('news_to_date', array('or'=> array(
            0 => array('date' => true, 'from' => $todayDate),
            1 => array('is' => new Zend_Db_Expr('null')))
        ), 'left')
        // ->addAttributeToSort('news_from_date', 'desc')

        ;

    if(count($productIds)) {
        $collection->addFieldToFilter('entity_id', array('in'=>$productIds));
    }

    return $collection;
}

希望这会有帮助

不起作用，但我已经解决了这个问题（希望它能帮助别人）：

• 首先，转到CMS->WIDGETS，然后创建Catalog New Products List的小部件。在内部，进行新的布局更新：显示在锚类别、主要内容、产品网格上

• 其次，转到template/catalog/product/widget/new/content/new_grid.phtml，然后添加以下内容：

          $currentCategory = Mage::registry('current_category');
          $category_model = Mage::getModel('catalog/category');
          $all_child_categories = $category_model->getResource()->getAllChildren($currentCategory);
  

      $visualizzo="";
  
          $diff = array_diff($all_child_categories, $_product->getCategoryIds());
          if(count($diff)==count($all_child_categories)){
              $visualizzo="display:none;";
          }
  

• 第三，在foreach（$\u products->getItems（）作为$\u product）之后添加以下内容：

          $currentCategory = Mage::registry('current_category');
          $category_model = Mage::getModel('catalog/category');
          $all_child_categories = $category_model->getResource()->getAllChildren($currentCategory);
  

      $visualizzo="";
  
          $diff = array_diff($all_child_categories, $_product->getCategoryIds());
          if(count($diff)==count($all_child_categories)){
              $visualizzo="display:none;";
          }
  

• 最后，在li class=“item”中有一个样式，将其放入：
