Yii2.0框架实现带分页的多条件搜索功能示例

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 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]);
}
