magento - 侧栏中的 Magento 类别和子类别

Question

我需要在左侧或右侧导航中显示类别和子类别，还需要在 Magento 中显示两个级别的类别。请给我提意见.....

例如：

categories
    ----sub1
        ---sub2

Answer 1

在左侧栏中添加类别导航 -

在您的主题中创建新文件“categorymenu.phtml” - template\catalog\navigation\categorymenu.phtml

将以下代码放入其中 -

<div class="block block-category">
 <div class="inside-box">
 <div class="block-title block-category-title"><h2><?php echo $this->__('Categories') ?></h2></div>
 <div class="block-category-navigation">
 <ul id="category-nav"> 
 <?php foreach ($this->getStoreCategories() as $_category): ?>  
 <?php if($_category->name!=""):  ?>    
 <li><?php echo $this->drawItem($_category) ?></li> 
 <?php endif?>  
 <?php endforeach ?>    
 </ul>  
 </div> 
 </div> 
</div>

然后在位于主题文件夹中的 catalog.xml 文件中调用它 -

主题\布局\catalog.xml。看起来像 ：

<reference name="left">

<block type="catalog/navigation" name="catalog.categorymenu" after="top.search" template="catalog/navigation/categorymenu.phtml"/> <-- this is new block added by us -->

 <block type="core/template" name="left.permanent.callout" template="callouts/left_col.phtml">

...
...
</reference>

Answer 2

转到布局 xml 文件夹...

/app/design/frontend/default/default/layout/catalog.xml

打开 catalog.xml 并粘贴它...

    <reference name="left">
            <block type="catalog/navigation" name="catalog.leftnav" template="catalog/navigation/left_nav.phtml" />
</reference>

进一步修改了.phtml文件..

<?php
$obj = new Mage_Catalog_Block_Navigation();
$store_cats = $obj->getStoreCategories();
$current_cat    = $obj->getCurrentCategory();
$current_cat    = (is_object($current_cat) ? $current_cat->getName() : '');

foreach ($store_cats as $cat) {
    if ($cat->getName() == $current_cat) {
        echo '<li class="current"><a href="'.$this->getCategoryUrl($cat).'">'.$cat->getName()."</a>\n<ul>\n";
        foreach ($obj->getCurrentChildCategories() as $subcat) {
            echo '<li><a href="'.$this->getCategoryUrl($subcat).'">'.$subcat->getName()."</a></li>\n";
        }
        echo "</ul>\n</li>\n";
    } else {
        echo '<li><a href="'.$this->getCategoryUrl($cat).'">'.$cat->getName()."</a></li>\n";
    }
}
?>

现在刷新缓存和重新索引过程......
