无法在magento上显示级别3子类别

我会问如何在magento上创建子类别

这个代码只显示2级的子类别，我需要进入3级

这是我的密码

<div class="category-products <?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('parent_cat_name')->toHtml() ?>">
<?php  echo "<ol class='subcat_list'>"; ?>

 <?php
    $currentCat = Mage::registry('current_category');

    if ( $currentCat->getParentId() == Mage::app()->getStore()->getRootCategoryId() )
    {
        // current category is a toplevel category
        $loadCategory = $currentCat;

    }
    else
    {
        // current category is a sub-(or subsub-, etc...)category of a toplevel category
        // load the parent category of the current category
        $loadCategory = Mage::getModel('catalog/category')->load($currentCat->getParentId());
        // @TODO enhance for more nested category levels to display sub-categories
    }    
    $subCategories = explode(',', $loadCategory->getChildren());

    foreach ( $subCategories as $subCategoryId )
    {
        $cat = Mage::getModel('catalog/category')->load($subCategoryId);

        if($cat->getIsActive())
        {       
            <?php  echo "<ol class='subcat_list'>"; ?>                                                      
                echo '<li><a href="'.$cat->getURL().'">'.$cat->getName().'</a>'.'</li>';
            <?php  echo "</ol>"; ?>
        }
    }

?>
<?php  echo "</ol>"; ?>
</div>

这里解释了如何递归生成类别树
检查此项：
确保在“管理”面板中设置的类别级别超过3级

系统->配置->目录->类别顶部导航->最大深度
将类别创建为第三级意味着父级>子级>子级之后，请确保已将3层深度分配到Magento中，以便导航到系统>配置>目录>类别顶部导航>最大深度

使用下面的代码并进行检查

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











希望能有帮助
