Yii2.0 多條件搜索 帶分頁

                                       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層

<?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',"&nbsp",Html::input('text','title');
echo '簡介',"&nbsp",Html::input('text','content');
echo Html::submitButton('提交');
ActiveForm::end();
echo "<br/>";
echo "<br/>";
?>

顯示在v層的分頁

<?php
echo LinkPager::widget([
    'pagination'=>$pages,
    'nextPageLabel'=>'下一頁',
    'firstPageLabel'=>'首頁'
])
?>

                                                   方法二（不帶分頁  是另外一種方法）

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]);
}
