ecshop 首页调用全部分类树 并且分类下的品牌 &调用商品分类指定分类下级分类

index.dwt里代码  

            <!--{foreach from=get_categories_tree(0) item=cat name=cat0}-->

               <div id="JS_hide_side_menu_{$smarty.foreach.cat0.iteration}" class="item all" onmouseover="showMenu(this,'side','{$smarty.foreach.cat0.iteration }')" onmouseout="hideMenu(this,'side','{$smarty.foreach.cat0.iteration}')">

这里有个写法 foreach from里面可以写函数 函数里还可以写变量。。。。
