我正在开发一个具有 2 级(类别和子类别)菜单的 magento 网站,我想添加第 3 级,但我不知道如何让它工作,我需要帮助。
这是我用来获得第 1 和第 2 类别级别的代码,我怎样才能获得第 3 级别?
<div class="left_content">
<div class="menu">
<?php $_helper = Mage::helper('catalog/category') ?>
<?php $_categories = $_helper->getStoreCategories() ?>
<?php $currentCategory = Mage::registry('current_category') ?>
<?php if (count($_categories) > 0): ?>
<ul id="menu">
<?php foreach($_categories as $_category): ?>
<li class="sub">
<a href="<?php echo $_helper->getCategoryUrl($_category) ?>"><?php echo $_category->getName() ?></a>
<?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?>
<?php $_subcategories = $_category->getChildrenCategories() ?>
<?php if (count($_subcategories) > 0): ?>
<ul>
<?php foreach($_subcategories as $_subcategory): ?>
<li>
<a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>">
<?php echo $_subcategory->getName() ?>
</a>
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
</div>
</div>
