如何在smarty中創建無限深度類別子類別選擇框

Question

我試圖創建一個包含無限深度類別，子類別選擇框的選擇框。我有一個數組包含無限類別的子類別深度如下所示，

我想在TPL創建一個選擇框爲訪問者選擇合適的類別/子類別。在此先感謝

您可以使用Smarty的3 functions 在你的情況

PHP：

$smarty->assign("you_category_array", **$you_array**); 

的Smarty：

{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}
