Magento的 - 添加自定義屬性導航

我有下面的代碼，在Magento創建一個自定義菜單：Magento的 - 添加自定義屬性導航

我想自定義的類別屬性（menu_label）添加到菜單項。我已經使用這個教程創建了自定義類別屬性http://www.atwix.com/magento/add-category-attribute/

該屬性在管理中顯示正常，我可以將它打印到正常的模板文件中，但無法顯示在此菜單中。

我以爲$ this-> escapeHtml（$ category-> getMenuLabel（））會做到這一點，但這不會輸出任何東西。

任何想法？

你必須考慮一個事實，即Magento在開/關平面類別上的表現不一樣。我想你可能在你的情況下與平面類別，因爲它應該工作，否則。

（請檢查系統>配置>目錄>目錄>前端領域的「使用平面目錄範疇」，如果它被設置爲「是」，那是你的問題。

爲了解決這個問題此次在「前端」節點添加到您的config.xml：

<events> 
    <catalog_category_flat_loadnodes_before> 
     <observers> 
      <somemodule> 
       <type>singleton</type> 
       <class>somemodule/observer</class> 
       <method>addMenuAttributes</method> 
      </somemodule> 
     </observers> 
    </catalog_category_flat_loadnodes_before> 
</events>

然後在你的模塊的模型文件夾中創建一個Observer.php（模型文件夾應該在你的config.xml文件中聲明過，偏離航向）

這裏是觀察員代碼：

<?php 
class Somecompany_Somemodule_Model_Observer { 

    public function addMenuAttributes(Varien_Event_Observer $observer) { 
     $observer->getSelect()->columns(
       array('menu_label') 
     ); 
}

希望這會有所幫助，鴨舌

感謝的人!!!! – Magefast 2015-04-30 14:41:48

您assumtion是不正確的：

$this->escapeHtml($category->getMenuLabel())

這假設$類確實是一個分類模型（Mage_Catalog_Model_category）時INFACT它不是，它是一個節點目的。

，如果你看看這裏：

Mage_Catalog_Model_Observer::_addCategoriesToMenu()

你會發現，其中實際目錄模型用於創建被傳遞到導航程序作爲Varien_Data_Tree_Node數組。您可以在此處添加自定義屬性，然後在塊內部訪問它。

$categoryData = array(
    'name' => $category->getName(), 
    'id' => $nodeId, 
    'url' => Mage::helper('catalog/category')->getCategoryUrl($category), 
    'is_active' => $this->_isActiveMenuCategory($category), 
    'my_attribute' => $category->getData('my_attribute') 
);

然後，您就可以訪問您的自定義菜單塊內的屬性：

$child->getData('my_attribute'); 
//$this->escapeHtml($category->getData('my_attribute'))

試過，但得到了這個錯誤PHP致命錯誤：PHP致命錯誤：調用一個成員函數getData（）在272行的Navigation.php中的非對象。可能是非常簡單的事情。我是一個總新手:) – a1anm 2013-04-26 13:54:38
