有时候会需要生成三级、四级导航，甚至更多，下面的代码，就是生成多级导航。
<?php
$ecms_bq_sql=sys_ReturnEcmsLoopBq("select * from [!db.pre!]enewsclass where bclassid=2 order by myorder limit 7",14,24,0);
$bqno=0;
while($bqr=$empire->fetch($ecms_bq_sql))
{
$bqsr=sys_ReturnEcmsLoopStext($bqr);
$bqno++;
?>
<div class="bar"><h2><?=sub($bqr[classname],0,54,false)?></h2></div>
<?php
$ecms_bq_sql2=sys_ReturnEcmsLoopBq("select * from [!db.pre!]enewsclass where bclassid=$bqr[classid] order by myorder limit 8",14,24,0);
$bqno2=0;
while($bqr2=$empire->fetch($ecms_bq_sql2))
{
$bqsr2=sys_ReturnEcmsLoopStext($bqr2);
$bqno2++;
?>
<ul>
<li class="f"><h3><a href="<?=$public_r[newsurl]?><?=$bqr2[classpath]?>/" target="_blank"><?=sub($bqr2[classname],0,54,false)?></a></h3></li>
<li>
<?php
$ecms_bq_sql3=sys_ReturnEcmsLoopBq("select classid,classname,classpath from [!db.pre!]enewsclass where bclassid = $bqr2[classid] order by classid limit 100",0,24,0);
$bqno3=0;
while($bqr3=$empire->fetch($ecms_bq_sql3))
{
$bqsr3=sys_ReturnEcmsLoopStext($bqr3);
$bqno3++;
?>
<a href="<?=$public_r[newsurl]?><?=$bqr3[classpath]?>/" target="_blank"><?=sub($bqr3[classname],0,54,false)?></a>
<?php
}
?>
</li>
</ul>
<?php
}
?>
<?php
}
?>
