YII2 Activedataprovider 类分页的使用

下面以管理员列表为例说明Activedataprovider分页的具体使用

1.控制器中

public function actionIndex()
{
    $model=new Admin();
    $dataProvider = new ActiveDataProvider([
        'query' => Admin::find()->orderBy('id'),
        'pagination' => ['pageSize' => 5],//此处为分页设置，其中5为每页显示5条
    ]);
    return $this->render('index',[
        'model'=>$model,
        'dataProvider'=>$dataProvider
    ]);
}

2.view视图文件中

index.php中

<?=
GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        [
            'attribute' => 'name',//字段名
            'content' => function($dataProvider){
                return $dataProvider['name'];
            },
        ],
        'description',//字段名
        [
            'attribute' => 'created_at',
            'format' =>  ['date', 'php:Y-m-d H:i:s'],
        ],

        [
            'class' => 'yii\grid\ActionColumn',
            'header' => '操作',
            'template' => '{view}{update}{delete}',
            'headerOptions' => ['width' => '128', 'class' => 'padding-left-5px',],
            'contentOptions' => ['class' => 'padding-left-5px'],
            'buttons' => [
                'password' => function ($url, $model, $key) {
                    return Html::a('<span class="glyphicon glyphicon-edit"></span>', $url, [
                        'title' => '修改密码',
                        'data-method' => 'post',
                        'data-pjax' => '0',
                    ]);
                },
            ],
        ],
    ],
    /*'layout' => "{items}\n{pager}",*/  //此处注释显示条数信息
]); 
?>

分页和列表显示效果如下图:
