yii2实现数据分页显示

Posted 2020-06-27

1、控制器：IndexController.php

 1 <?php
 2 //引入分页类
 3 use yii\data\Pagination;
 4 use app\models\Index;
 5 
 6   public function actionidnex(){
 7        $data = Index::find()->andWhere([‘id‘ => ‘10‘]);
 8        $pages = new Pagination([‘totalCount‘ =>$data->count(), ‘pageSize‘ => ‘2‘]);
 9        $model = $data->offset($pages->offset)->limit($pages->limit)->all();
10        
11        return $this->render(‘index‘,[
12              ‘model‘ => $model,
13              ‘pages‘ => $pages,
14        ]);
15   }
16 ?>

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

 1 <?php
 2 //引入linkPager
 3 use yii\widgets\LinkPager;
 4 ?>
 5 
 6       foreach($model as $key=>$val)
 7       {
 8            //这里就是遍历数据了，省略......
 9       }
10        <!--显示页码-->
11       <?= LinkPager::widget([‘pagination‘ => $pages]); ?>
