导航一、二级同时调用
代码示例：
循环调用：
<?php
$ecms_bq_sql=sys_ReturnEcmsLoopBq("select * from [!db.pre!]enewsclass where bclassid=0 order by myorder limit 6",14,24,0);
$bqno=0;
while($bqr=$empire->fetch($ecms_bq_sql))
{
$bqsr=sys_ReturnEcmsLoopStext($bqr);
$bqno++;
?>
<li class="menu">
<a href="<?=$public_r[newsurl]?><?=$bqr[classpath]?>/" title="<?=sub($bqr[classname],0,54,false)?>">
<?=sub($bqr[classname],0,54,false)?>
</a>
<ul class="sub">
<?php
$ecms_bq_sql2=sys_ReturnEcmsLoopBq("select * from [!db.pre!]enewsclass where bclassid=$bqr[classid] order by myorder limit 20",14,24,0);
$bqno2=0;
while($bqr2=$empire->fetch($ecms_bq_sql2))
{
$bqsr2=sys_ReturnEcmsLoopStext($bqr2);
$bqno2++;
?>
<li>
<a href="<?=$public_r[newsurl]?><?=$bqr2[classpath]?>/" title="<?=sub($bqr2[classname],0,54,false)?>">
<?=sub($bqr2[classname],0,54,false)?>
</a>
</li>
<?php
}
?>
</ul>
</li>
<?php
