PHP无限分类(树形类)(3)

$result=$db->query(……);//这里查询得到结果集，注意结果集为数组
$tree= new Tree($result);
$arr=$tree->leaf(0);
$nav=$tree->navi(15);
$smarty->assign(‘arr',$arr);
$smarty->assign(‘nav',$nav);
$smarty->display(‘test.html');

在smarty模板中这样递归：

复制代码 代码如下:

<!--导航-->
<div>
<{foreach $nav as $n}>
    <{if $n@iteration != $n@last}>
        <{$n.name}> ->
    <{else}>
        <{$n.name}>
    <{/if}>
<{/foreach}>
</div>
<!--树形菜单-->
<div>
<{function name=menu}>
    <ul>
        <{foreach $data as $entry}>
            <li>
                <span><{$entry.name}></span> <{*注意字段要改成自己的字段哦*}>
            <{if isset($entry.child)}>
                <{call name=menu data=$entry.child}>
            <{/if}>
            </li>
        <{/foreach}>
    </ul>
<{/function}>
<{call name=menu data=$arr}> <{*注意在这里$arr才是模板变量*}>
</div>
