如何在Magento中顯示當前類別的兒童子類別

Question

我想通過爲我的單獨類別提供一些帶有子級鏈接的選項卡來讓我的大型目錄具有一定的平板友好性。因此，如果用戶點擊（第一級）頭部類別，則需要顯示包含每個直接孩子的圖片，描述和網址的所有塊以及所示的所有基礎（第三級）兒童類別的列表（第二級別）分類。請問你們有沒有這麼熱心檢查我的代碼？

<?php 
    $layer = Mage::getSingleton('catalog/layer'); 
    $_category = $layer->getCurrentCategory(); 
    $_categories = $_category->getCollection() 

->addAttributeToSelect(array('url_key','name','image','all_children','is_anchor','description')) 
    ->addAttributeToFilter('is_active', 1) 
    ->addIdFilter($_category->getChildren()) 
    ->setOrder('position', 'ASC') 
    ->joinUrlRewrite(); 
?> 

      <?php $children = explode(",", $this->getCurrentCategory()->getChildren()); ?> 

    <ul class="category-grid"> 
    <div class="category-list"> 
     <?php foreach($children as $child): ?>

，你可以在此通過下面的代碼，也指在底部

鏈接，你可以用這個

<?php $_helper = Mage::helper('catalog/category') ?> 
<?php $_categories = $_helper->getStoreCategories() ?> 
<?php $currentCategory = Mage::registry('current_category') ?> 
<?php if (count($_categories) > 0): ?> 
    <ul class="category"> 
     <?php foreach($_categories as $_category): ?> 
      <li> 
       <a href="<?php echo $_helper->getCategoryUrl($_category) ?>"> 
        <?php echo $_category->getName() ?> 
       </a> 
       <?php if ($currentCategory->getId() && $currentCategory->getId() == $_category->getId()): ?> 
        <?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?> 
        <?php $_subcategories = $_category->getChildrenCategories() ?> 
        <?php if (count($_subcategories) > 0): ?> 
         <ul class="subcategory"> 
          <?php foreach($_subcategories as $_subcategory): ?> 
           <li> 
            <a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>"> 
             <?php echo $_subcategory->getName() ?> 
            </a> 
           </li> 
          <?php endforeach; ?> 
         </ul> 
        <?php endif; ?> 
       <?php endif; ?> 
      </li> 
     <?php endforeach; ?> 
    </ul> 
<?php endif; ?> 

編輯被去

<ul class="subcategory"> 
      <? foreach ($_categories as $_category):?> 
       <? if($_category->getIsActive()): 
         $cur_subcategory=Mage::getModel('catalog/category')->load($_category->getId()); 
         $layer = Mage::getSingleton('catalog/layer'); 
         $layer->setCurrentCategory($cur_subcategory); 
         ?> 

        <li><a href="<?php echo $this->getCategoryUrl($_category)?>"> <?php echo $_category->getName()?></a></li> 
       <? endif;?> 

     <?endforeach?> 

     </ul> 

或者你可以去扔this Detail documentation，我相信這對你真的很有幫助。

Answer 2

// get current category 
$current_category = $layer->getCurrentCategory(); 

// get sub categories of current category 
$parent_categories = Mage::getModel('catalog/category')->getCategories($current_category->getId()); 

// go through each sub category and get their sub categories. 
foreach($parent_categories as $child_category) 
{ 
    $child_category_id = $child_category->getId(); 
    $grandchild_categories = Mage::getModel('catalog/category')->getCategories($child_category_id); 

}
