我们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} |
