在带有图像缩略图的Magento导航菜单中显示子类别描述

Question

我有一个垂直导航菜单，显示了父类别和子类别以及图像缩略图和标题。我还想在子类别名称下面显示每个子类别的简短描述。目前导航显示列表中父类别foreach子类别的描述。

我该如何改变？

下面的代码：

<?php $_helper = Mage::helper('catalog/category') ?> 
<?php $_categories = $_helper->getStoreCategories() ?> 
<?php $currentCategory = Mage::registry('current_category') ?> 
<?php if (count($_categories) > 0): ?> 
<div class="left-nav-vertical visible-desktop visible-tablet hidden-phone" id="nav-vertical"> 
<ul class="nav nav-tabs-left" id="dcjq-vertical-mega-menu"> 
<li class="dropdown open visible-desktop visible-tablet hidden-phone" id="left"> 
<a class="dropdown-toggle"><?php echo $this->__('Shop by Department') ?><b class="caret"></b></a> 
<ul class="dropdown-menu">         
<ul id="mega" class="menu"> 
<!--Top Category--> 
<?php foreach($_categories as $_category): ?> 
<li id="menu-item-1"> 
<a href="<?php echo $_helper->getCategoryUrl($_category) ?>"> <?php echo $_category->getName() ?></a> 
<ul> 
<?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?> 
<?php $_subcategories = $_category->getChildrenCategories() ?> 
<?php if (count($_subcategories) > 0): ?> 
<?php foreach($_subcategories as $_subcategory):$products = Mage::getResourceModel('catalog/product_collection')->addCategoryFilter($_subcategory)->addAttributeToSelect('small_image');$products->getSelect()->order(new Zend_Db_Expr('RAND()'))->limit(1);$products->load();?> 
<!-- SubCategory--> 
<ul> 
<li class="media"> 
<a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>"> 
<p class="product-name"><?php echo $_subcategory->getName() ?></p> </a> 
<?php foreach($products as $product) { ?> 
<?php $cur_category=Mage::getModel('catalog/category')->load($_category->getId()); 
$layer = Mage::getSingleton('catalog/layer'); 
$layer->setCurrentCategory($cur_category); ?> 
<!-- Show image --> 
<a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>" class="pull-left"> 
<img src="<?php echo $this->helper('catalog/image')->init($product, 'small_image')->resize(50, 50); ?>" class="static-thumbs" width="50" height="50" alt="<?php echo $_subcategory->getName() ?>" /></a> 

<!-- End Show image--> 

<!-- Show sub category Description --> 
<li id="menu-item-4" class="pull-right"> 
<?php break; } ?> 
<span><em> 
<?php $children = explode(",", $this->getCurrentCategory()->getChildren()); ?> 
     <?php foreach($children as $child): ?> 
      <?php $_child = Mage::getModel('catalog/category')->load($child); ?> 
      <li><?php echo $_child->getDescription(); ?></li> 
     <?php endforeach; ?> 

</em></span> 
</li> 
<!-- End show category Description --> 
</ul> 
<div class="clearer"></div> 
<!-- end of subcats --> 
<?php endforeach; ?> 
</li> 
<?php endif; ?> 
</ul> 
<!-- end of parent cats --> 
<?php endforeach; ?> 
</li> 
</ul> 
</ul> 
</li> 
</ul> 
</div> 
<?php endif; ?> 
<!--- Close Navigation Menu --> 

<script type="text/javascript"> 
jQuery.noConflict(); 
jQuery(document).ready(function(){ 
    jQuery('#mega').dcVerticalMegaMenu({ 
    rowItems: '1', 
    speed: 'fast', 
    effect: 'slide', 
    direction: 'right' 
    }); 
}); 
</script> 
<!--- Closed Navigation Menu --> 

我试图改变这一行：

<em><?php echo 
> $this->htmlEscape($_category->getDescription()) ?></em> 

要这样：

<em><?php echo 
> $this->htmlEscape($_subcategory->getDescription()) ?></em> 

，但没有喜悦！

任何帮助将受到欢迎...

此代码为希望做同样的事情的人。您将需要调整样式并编辑foreach循环以适应您的需求。

<?php $_helper = Mage::helper('catalog/category') ?> 
<?php $_categories = $_helper->getStoreCategories() ?> 
<?php $currentCategory = Mage::registry('current_category') ?> 
<?php if (count($_categories) > 0): ?> 

<!--Top Category--> 
<?php foreach($_categories as $_category): ?> 
<li id="menu-item-1"> 
<a href="<?php echo $_helper->getCategoryUrl($_category) ?>"> <?php echo $_category->getName() ?></a> 
<ul> 
<?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?> 
<?php $_subcategories = $_category->getChildrenCategories() ?> 
<?php if (count($_subcategories) > 0): ?> 
<?php foreach($_subcategories as $_subcategory):$products = Mage::getResourceModel('catalog/product_collection')->addCategoryFilter($_subcategory)->addAttributeToSelect('small_image');$products->getSelect()->order(new Zend_Db_Expr('RAND()'))->limit(1);$products->load();?> 
<!-- SubCategory--> 

<a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>"> 
<p class="product-name"><?php echo $_subcategory->getName() ?></p> </a> 
<?php foreach($products as $product) { ?> 
<?php $cur_category=Mage::getModel('catalog/category')->load($_category->getId()); 
$layer = Mage::getSingleton('catalog/layer'); 
$layer->setCurrentCategory($cur_category); ?> 
<!-- Show image --> 
<a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>" class="pull-left"> 
<img src="<?php echo $this->helper('catalog/image')->init($product, 'small_image')->resize(50, 50); ?>" class="static-thumbs" width="50" height="50" alt="<?php echo $_subcategory->getName() ?>" /></a> 

<!-- End Show image--> 

<!-- Show sub category Description --> 

<?php break; } ?> 
<span><em> 
<?php $children = explode(",", $this->getCurrentCategory()->getChildren()); ?> 
     <?php foreach($children as $child): ?> 
      <?php $_child = Mage::getModel('catalog/category')->load($child); ?> 
      <li><?php echo $_child->getDescription(); ?></li> 
     <?php endforeach; ?> 

</em></span> 

<!-- End show category Description --> 

<!-- end of subcats --> 
<?php endforeach; ?> 

<?php endif; ?> 

<!-- end of parent cats --> 
<?php endforeach; ?> 

<?php endif; ?>
