我有一个这样的网格视图。在mysql查询的帮助下计算列并相应地显示。

<?php
  $subquery = Adanalytics::find()->
            select('id,ad_id,date_event,max(cpc) cpclick,max(cpv) cpview,max(impression) impression,max(view) view,max(clicks) clicks,visitor_ip,publisher_id')->
            from('ad_analytics')->
            where(['publisher_id' =>  Yii::$app->user->identity->id ])->
            groupBy('ad_id,date_event,visitor_ip');
  $query=Adanalytics::find()->
        select('ad_id,date_event,sum(cpclick) total_click_cost,sum(cpview) total_view_cost,sum(impression) total_impression,sum(view) total_views,sum(clicks) total_clicks,publisher_id')->
        from(['t'=>$subquery])->
        groupBy('t.ad_id,t.date_event');
 ?>

    <?= GridView::widget([

    'dataProvider'=>new ActiveDataProvider([
      'query' => $query,
    ]),
    'filterModel' => $searchModel,
    'columns' => [
        ['class' => 'yii\grid\SerialColumn'],
        'ad_id',
        'total_impression',
        'total_views',
        'total_clicks',
        'total_click_cost',
        'total_view_cost',
        'date_event',

        ['class' => 'yii\grid\ActionColumn'],
    ],
]); ?>

我想在这个网格视图的底部显示一个总计列。
例如

'grand_total_impression',
        'grand_total_views', //This is the sum of all displayed views
        'grand_total_clicks',//This is the sum of all displayed clicks
        'grand_total_click_cost',//THis is the sum of all displayed cost
        'grand_total_view_cost',//This is the sum of all displayed view cost

为了做到这一点,我的控制器中有这样的代码。

public function actionIndex()
    {
        $searchModel = new Adanalytics2Search();
        $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
        $grandTotal = [];
        foreach ($dataProvider->getModels() as  $value) {
          // var_dump($value);
          // exit();
            $grandTotal['total_click_cost'] += $value['total_click_cost'];
            $grandTotal['total_view_cost'] += $value['total_view_cost'];
        }
        //var_dump($dataProvider);
         return $this->render('index', [
             'searchModel' => $searchModel,
             'dataProvider' => $dataProvider,
             'grandTotal'  => $grandTotal,
         ]);
    }

但它正以这种方式产生误差。

Undefined index: total_click_cost

我哪里出错了?或者有没有别的办法来解决这个问题?

这解决了问题。
这是在网格列中。

[
              'attribute'=>'total_impression',
              'pageSummary' => true
            ],

在网格视图中

'showPageSummary' => true,
eeq64g8w

eeq64g8w2#

use kartik\grid\GridView;

// Create a panel layout for your GridView widget
echo GridView::widget([
'dataProvider'=> $dataProvider,
'filterModel' => $searchModel,
'columns' => $gridColumns,
'showPageSummary' => true
]);

类似问题:yii2:kartik gridview页脚中列的和

我强烈建议您使用katrik gridview。它可以更好地处理页面摘要并实现许多其他用法。或者在gridview中添加'showpagesummary'=>true以显示列摘要。
