本文实例讲述了smarty实现多级分类的方法。分享给大家供大家参考。具体分析如下:

这里简单的介绍一下利用php smarty 多级分类读出与循环方法,,单循环很简单,但是多级就要复杂一点,下面我们来看看,感兴趣的朋友可以看来一下:

复制代码 代码如下:

$result=mysql_query("SELECT id,description,parent_id,name,sort_order FROM article_categoey WHERE parent_id=0 order by id");
while ($row = mysql_fetch_array($result)){
$class[]=$row;
//$row['id']是分类id,parent_id是子分类所属id
$result_sub=mysql_query("SELECT id,description,parent_id,name,sort_order FROM article_categoey WHERE parent_id='".$row['id']."' order by id");
while ($row_sub = mysql_fetch_array($result_sub)) {
$subclass[]=$row_sub;
}
$smarty->assign("subclass", $subclass);
}
$smarty->assign("class", $class);
$smarty->display('articles.html');
?>


HTML 代码如下:

复制代码 代码如下:


    {foreach name=cat from=$class item=cat}
  • {$cat.name}[{$cat.id}]


    • {foreach name=subcat from=$subclass item=subcat}
      {if $subcat.parent_id==$cat.id}
    • {$subcat.name}[{$subcat.parent_id}]

    • {/if}
      {/foreach}

    {/foreach}

运行结果如下图所示:

希望本文所述对大家的PHP程序设计有所帮助。
