YII2中ActiveDataProvider与GridView的配合使用&DetailView

 $provider = new ActiveDataProvider([

            //为ActiveDataProvider对象提供一个查询对象

            'query' => $query,

            //设置分页参数

            'pagination' => [

                //分页大小

                'pageSize' => 3,

                //设置地址栏当前页数参数名

                'pageParam' => 'p',

                //设置地址栏分页大小参数名

                'pageSizeParam' => 'pageSize',

            ],

            //设置排序

            'sort' => [

                //默认排序方式

                'defaultOrder' => [

                    'id' => SORT_DESC,

                ],

                //参与排序的字段

                'attributes' => [

                    'id', 'name', 'sex', 'age'

                ],

            ],

        ]);

 

$getInfo =  \common\models\GachaCombineGoods::find()->count();总数据

$dataProvider->setTotalCount($getInfo); 设置分页显示

DetailView:主要展示详情信息，只展示一条数据

 （2）ActiveDataProvider：也可以在rules中定义需要搜索的字段

可以是二维数组：

$resultData = [
    ["id"=>1,"name"=>"Cyrus","email"=>"risus@consequatdolorvitae.org"],
    ["id"=>2,"name"=>"Justin","email"=>"ac.facilisis.facilisis@at.ca"],
    ["id"=>3,"name"=>"Mason","email"=>"in.cursus.et@arcuacorci.ca"],
    ["id"=>4,"name"=>"Fulton","email"=>"a@faucibusorciluctus.edu"]
];
//不需要在class中添加元素
$dataProvider = new ArrayDataProvider([
    'allModels' => $resultData,
    'pagination' => false, // 可选 不分页
    'sort' => [
        'attributes' => ['id', 'name', 'email'],
    ],
]); 

GridView 中显示：

[
    'attribute'=>'out_trade_no',
    'label'=>'表订单号'

],

[
    'attribute' => 'total_fee',
    'label'=>'价值',
    'value' => function ($model) {
        return $model['total_fee'] / 100;
    }
],

[
    'attribute'=>'created_at',
    'label'=>'创建时间',
    'value'=>function($model){
        return date("Y-m-d H:i:s",$model['created_at']);
    }
或者：

'attribute' => 'created_at',

'format' => ['date', 'Y-m-d H:i:s'],

],

后端分页可以：

$dataProvider = new ArrayDataProvider([
    'allModels' => $res['stocks'],
    'pagination' => false,
]);
$pages = new Pagination(['totalCount' => $res['total']]);

前端分页可以：

<?=
    LinkPager::widget([
    'pagination' => $pages,
])
?>
