前几天给一个客户定制开发网站，他需要二级栏目导航下的分类再显示，如果用静态的，太麻烦了。通过研究，终于得到了方法：
<div class=”nav”>
<div class=”nav”>
<div class=”nav-inner”>
<div class=”clearfix nav-inner” id=”menu”>
<ul class=”navlist”>
<li><a href=”[!—news.url–]”><span>网站首页</span></a></li>
[e:loop={“select classid,classname,islast,sonclass from {$dbtbpre}enewsclass where bclassid=’0′ order by myorder,classid ASC limit 11″,0,24,0}]
<?php
$classurl=sys_ReturnBqClassname($bqr,9); //取得栏目地址
$tbname=$class_r[$bqr[classid]][tbname]; //取得表名
$navshow=ReturnClassAddField($bqr[classid],’nav’); //取得栏目自定义字段navshow值?>
<li><a href=”<?=$classurl?>” target=”_blank”><span>
<?=$bqr[classname]?>
</span></a>
<?php
//值为0时显示二级，值为1时不显示二级
if(!$navshow){
//终极栏目Start
if(!$bqr[islast]) {
//判断是否有子栏目Start
if($bqr[sonclass]) {
echo ‘<ul>’;
//循环栏目下的子栏目Start
$newsclass=$empire->query(“select classid,classname from “.$dbtbpre.”enewsclass where bclassid=”.$bqr[classid].” order by myorder,classid desc limit 10″);
while($classr=$empire->fetch($newsclass)) {
$classrurl=sys_ReturnBqClassname($classr,9); //取得子栏目地址
?>
<li><a href=”<?=$classrurl?>”><?=$classr[classname]?></a></li>
<?php
}
//循环栏目下的子栏目End
echo ‘</ul>’;
}
//判断是否有子栏目End
}
//终极栏目End
else
//非终极栏目Start
{
$numinfo=$empire->gettotal(“select count(*) as total from “.$dbtbpre.”ecms_”.$tbname.” where classid=”.$bqr[classid]); //统计子栏目信息
//判断终极栏目下是否有信息Start
if($numinfo){
echo ‘<ul>’;
//循环栏目下的信息Start
$newsinfo=$empire->query(“select title,id,classid,newspath,filename,groupid,titleurl from “.$dbtbpre.”ecms_”.$tbname.” where classid=”.$bqr[classid].” order by newstime desc limit 10″);
while($infor=$empire->fetch($newsinfo)) {
$titleurl=sys_ReturnBqTitleLink($infor);
?>
<li><a href=”<?=$titleurl?>”><?=$infor[title]?></a></li>
<?php
}
//循环栏目下的信息End
echo ‘</ul>’;
}
//判断终极栏目下是否有信息End
}
//非终极栏目End
}
?>
</li>
[/e:loop]
</ul>
</div>
</div>
</div>
