Yii2.0 多条件搜索 带分页

                               方法一

  在控制器中

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]);

}

在V层

<?php
use yiihelpersHtml;
use yiiwidgetsActiveForm;
use yiihelpersUrl;
use yiiwidgetsLinkPager;
?>


<?php
$form=ActiveForm::begin([
'action'=>Url::toRoute(['show']),
'method'=>'get',
])
;
echo '姓名',"&nbsp",Html::input('text','title');
echo '简介',"&nbsp",Html::input('text','content');
echo Html::submitButton('提交');
ActiveForm::end();
echo "<br/>";
echo "<br/>";
?>

显示在v层的分页

<?php
echo LinkPager::widget([
'pagination'=>$pages,
'nextPageLabel'=>'下一页',
'firstPageLabel'=>'首页'
])
?>


            方法二(不带分页 是另外一种方法)

public function actionShow(){
  $titles=Yii::$app->request->post('title');
  $content=Yii::$app->request->post('content');
  $where=1;
  if($titles!=""){
    $where.=" and title like '%$titles%'";
  }
  if($content!=""){
    $where.=" and content like '%$content%'";
  }
  $sql="select * from votes where $where";
  $users=Yii::$app->db->createCommand($sql)->query();
  return $this->render('show',['data'=>$users]);
}
