如何在Magento中显示当前类别的儿童子类别

Question

我想通过为我的单独类别提供一些带有子级链接的选项卡来让我的大型目录具有一定的平板友好性。因此，如果用户点击（第一级）头部类别，则需要显示包含每个直接孩子的图片，描述和网址的所有块以及所示的所有基础（第三级）儿童类别的列表（第二级别）分类。请问你们有没有这么热心检查我的代码？

<?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">

，你可以在此通过下面的代码，也指在底部

链接，你可以用这个

<?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; ?> 

编辑被去

<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，我相信这对你真的很有帮助。

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); 

}
