我想在tpl中创建一个选择框，供访问者选择适当的类别/子类别。提前致谢
答案 0 :(得分：2)
你可以使用Smarty 3和functions 在你的情况下
PHP：
$smarty->assign("you_category_array", **$you_array**);
Smarty的：
{function name=menu level=0}
<ul class="level{$level}">
{foreach $data as $category}
{if is_array($category.subcategories)}
<li>{$category.cata_name}
{menu data=$category.subcategories level=$level+1}</li>
{else}
<li>{$category.cata_name}</li>
{/if}
{/foreach}
</ul>
{/function}
{menu data=$you_category_array}
