,织梦dedecms判断seo标题是否为空的解决方法：,如果为空时，则自动调用栏目名称的代码如下：,{dede:field name='id' runphp='yes'},$tid=@me;,$dsql = $db = new DedeSql(false);,$sql='select seotitle from dede_arctype where id='.$tid;,$arr = $db->GetOne($sql);,$seotitle=$arr['seotitle'];,if($seotitle==""),{,$sql='select typename from dede_arctype where id='.$tid;,$arr = $db->GetOne($sql);,@me=$arr['typename'];,},else,{,@me=$seotitle;,},
