用织梦系统做个模板开发的朋友可能会原道这样的一种情况:在调用二级菜单的时候,如果有子栏目,就显示二级菜单,如果没有就不显示。如何实现这样的效果功能,361模板下面给出代码:
{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}
完成。
