yii2.0分页

分页有两种方法：

第一种：

控制器：

use yii\data\ActiveDataProvider;  //引用
use yii\data\Pagination;    //分页类


public function actionShow1()
{
    $query=Login::find();    //Login是model名
    $provider = new ActiveDataProvider([
            'query' => $query,
            'pagination' => [
                'pageSize' => 5,   //每页条数
            ],
        ]);
     return $this->render('index', [
            'model' => $query,
            'dataProvider' => $provider
        ]);
   
}

view层：index.php

<?php

use yii\helpers\Html;
use yii\grid\GridView;
use yii\widgets\LinkPager;
/* @var $this yii\web\View */
/* @var $dataProvider yii\data\ActiveDataProvider */

$this->title = '展示';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="login-index">

    <h1><?= Html::encode($this->title) ?></h1>

    <p>
        <?= Html::a('添加', ['index'], ['class' => 'btn btn-success']) ?>
    </p>    
  <?= GridView::widget([
       'dataProvider' => $dataProvider,
        'pager'=>[
               //'options'=>['class'=>'hidden']//关闭自带分页
               'firstPageLabel'=>"首页",
                'prevPageLabel'=>'上一页',
                'nextPageLabel'=>'下一页',
                'lastPageLabel'=>'尾页',
        ],
       'columns' => [
           //['class' => 'yii\grid\SerialColumn'],
           'login_id',
           'login_name',
           ['attribute'=>'addtime',
           'format'=>['date','php:m-d h:i:s'],
           ],
           ['class' => 'yii\grid\ActionColumn'],
       ],
   ]);
   
   ?> 
</div>

效果为:

 第二种方法：

控制器：

public function actionShow1()
{
    $query=Login::find();
    
    $pagination = new Pagination([
            'defaultPageSize' => 5,//每页显示条数
            'totalCount' => $query->count(),//总条数
        ]);//分页传参

       $countries = $query->orderBy('login_id asc')
            ->offset($pagination->offset)//偏移量
            ->limit($pagination->limit)
            ->all();//查询到的分页后的数据
     return $this->render('index', [
            'countries' => $countries,
            'pagination' => $pagination,
        ]);
   
}

views层：

<?php

use yii\helpers\Html;
use yii\grid\GridView;
use yii\widgets\LinkPager;  //引用分页link
/* @var $this yii\web\View */
/* @var $dataProvider yii\data\ActiveDataProvider */

$this->title = '展示';
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="login-index">

    <h1><?= Html::encode($this->title) ?></h1>

    <p>
        <?= Html::a('添加', ['index'], ['class' => 'btn btn-success']) ?>
    </p>
<center>
    <table border="1" cellpadding ="5">
    <tr>
        <td>编号</td>
        <td>名称</td>
        <td>添加时间</td>
        <td>操作</td>
    </tr>
    <?php foreach ($data as $key => $v): ?>
    <tr>
        <td><?= Html::encode($v['login_id'])?></td>
        <td><?= Html::encode(mb_substr($v['login_name'],0,3)."*")?></td>
        <td><?= Html::encode(date('Y-m-d H:i:s',$v['addtime']))?></td>
        <td><?= Html::a('查看', ['select','login_id'=>$v['login_id']], ['class' => 'btn btn-success']) ?>
        <?= Html::a('修改', ['update','login_id'=>$v['login_id'],'a'=>$v['login_id']], ['class' => 'btn btn-success']) ?></td>

    </tr>
    <?php endforeach; ?>
    </table>
    <?= LinkPager::widget([
        'pagination'=>$pagination,
        //'options'=>['class'=>'hidden']//关闭自带分页
       'firstPageLabel'=>"首页",
        'prevPageLabel'=>'上一页',
        'nextPageLabel'=>'下一页',
        'lastPageLabel'=>'尾页',
    ])
    ?>

</center>
</div>

效果图：

以上就是两种分页方法。
