本文实例讲述了Yii2.0框架实现带分页的多条件搜索功能。分享给大家供大家参考，具体如下：

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 yii\helpers\Html;
use yii\widgets\ActiveForm;
use yii\helpers\Url;
use yii\widgets\LinkPager;
?>

<?php
$form=ActiveForm::begin([
 'action'=>Url::toRoute(['show']),
 'method'=>'get',
]);
echo '姓名'," ",Html::input('text','title');
echo '简介'," ",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]);
}
