我们做织梦模版的时候,在调用二级菜单的时候,会遇到这样的问题,如果有子栏目,就显示二级菜单,如果没有就不显示,下面给出代码:

 

{dede:channelartlist row=8 typeid='1,2,3,4,5'}

<li class="tab dropdown">

     <a href="{dede:field.typeurl/}" class="tablink arwlink" title="{dede:field.typename/}">{dede:field.typename/}</a>

     {dede:field name=typeid runphp="yes"}

     global $dsql; $sql = "SELECT id From `arctype` WHERE reid='@me' And ishidden<>1 order by sortrank asc limit 0, 100 ";

     $row = $dsql->GetOne($sql);

     @me=is_array($row)?'<ul class="subnav">':'';

     {/dede:field}

 

     {dede:channel type='son' noself='yes' }

         <a href="[field:typeurl/]">[field:typename/]</a>

     {/dede:channel}

     

     {dede:field name=typeid runphp="yes"}

     global $dsql; $sql = "SELECT id From `arctype` WHERE reid='@me' And ishidden<>1 order by sortrank asc limit 0, 100 ";

     $row = $dsql->GetOne($sql);

     @me=is_array($row)?'</ul>':'';

          {/dede:field}

</li>

{/dede:channelartlist}


THE END
