Yii2.0框架实现带分页的多条件搜索功能示例

public function actionShow(){
  $where['title']=Yii::$app- request- get('title');
  $where['content']=Yii::$app- request- get('content');
  $query=new Query();
  $query- from('votes');
  // votes 是表名
  if(!empty($where['title'])||!empty($where['content'])){
    $query- andFilterWhere(
      ['like','title',$where['title']]
    )- orFilterWhere(
      ['like','content',$where['content']]
    );
  }
  $users=$query- from('votes')- all();
  $pages = new Pagination(['totalCount' = $query- count(),'pageSize'= '2']);
  $users = $query- offset($pages- offset)- limit($pages- limit)- all();
  return $this- render('show',['data'= $users,'where'= $where,'pages'= $pages]);
}
