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
$form=ActiveForm::begin([
'action'=>Url::toRoute(['show']),
'method'=>'get',
]);
echo '姓名'," ",Html::input('text','title');
echo '简介'," ",Html::input('text','content');
echo Html::submitButton('提交');
ActiveForm::end();
echo "<br/>";
echo "<br/>";
?>
显示在v层的分页
<?php
echo LinkPager::widget([
'pagination'=>$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]);
}
