phtml对应的block文件

继承

Mage_Catalog_Block_Navigation

 

编写方法：

  

public function renderCategoriesMenuHtml_ter($level = 0, $outermostItemClass = '', $childrenWrapClass = '')     {         $activeCategories = array();         foreach ($this->getStoreCategories_ter() as $child) {             if ($child->getIsActive()) {                 $activeCategories[] = $child;             }         }         $activeCategoriesCount = count($activeCategories);         $hasActiveCategoriesCount = ($activeCategoriesCount > 0);         if (!$hasActiveCategoriesCount) {             return '';         }         $html = '';         $j = 0;         foreach ($activeCategories as $category) {             $html .= $this->_renderCategoryMenuItemHtml(                 $category,                 $level,                 ($j == $activeCategoriesCount - 1),                 ($j == 0),                 true,                 $outermostItemClass,                 $childrenWrapClass,                 true             );             $j++;         }         return $html;     }

 

 

 

public function getStoreCategories_ter()

    {         $helpers = Mage::helper('catalog/category');         return $helpers->getStoreCategories_ter();     }

help类

继承

Mage_Catalog_Helper_Category

 

public function getStoreCategories_ter($sorted=false, $asCollection=false, $toLoad=true)

    {         $parent     = 889;  //此处为：catelog ID！！！！！         $cacheKey   = sprintf('%d-%d-%d-%d', $parent, $sorted, $asCollection, $toLoad);         if (isset($this->_storeCategories[$cacheKey])) {             return $this->_storeCategories[$cacheKey];         }         /**          * Check if parent node of the store still exists          */         $category = Mage::getModel('catalog/category');         /* @var $category Mage_Catalog_Model_Category */         if (!$category->checkId($parent)) {             if ($asCollection) {                 return new Varien_Data_Collection();             }             return array();         }         $recursionLevel  = max(0, (int) Mage::app()->getStore()->getConfig('catalog/navigation/max_depth'));         $storeCategories = $category->getCategories($parent, $recursionLevel, $sorted, $asCollection, $toLoad);         $this->_storeCategories[$cacheKey] = $storeCategories;         return $storeCategories;     }

 

 

如果想省劲，直接在继承的类里面直接写，反正做成版本的东西又不升级，稳定才是王道！！
