yii2实现数据分页显示

1、控制器：IndexController.php

<?php
//引入分页类
use yii\data\Pagination;
use app\models\Index;

  public function actionidnex(){
       $data = Index::find()->andWhere(['id' => '10']);
       $pages = new Pagination(['totalCount' =>$data->count(), 'pageSize' => '2']);
       $model = $data->offset($pages->offset)->limit($pages->limit)->all();
       
       return $this->render('index',[
             'model' => $model,
             'pages' => $pages,
       ]);
  }
?>

好的，到这里，控制器部分基本就结束了。

2、我们接续看 view 里面的代码：idnex.php

<?php
//引入linkPager
use yii\widgets\LinkPager;
?>

      foreach($model as $key=>$val)
      {
           //这里就是遍历数据了，省略......
      }
       <!--显示页码-->
      <?= LinkPager::widget(['pagination' => $pages]); ?>
