我是新来的，我无法发表评论here

当我尝试在页脚中获得总和时，我遇到了问题。

我在控制器中的代码：

$searchModel = new ReceiptsSearch();
$sum = new ReceiptsSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
 return $this->render('index', [
   'searchModel' => $searchModel,
   'dataProvider' => $dataProvider,
   'sum'=>$sum,
   ]);

我的SearchModel代码：

public function search($params)
{
    $query = Receipts::find();
    $sum = $query->sum('price');
    $dataProvider = new ActiveDataProvider([
        'query' => $query,
    ]);

    $this->load($params);

    if (!$this->validate()) {
        return $dataProvider;
    }
    $query->joinWith('patient'); 
    $query->andFilterWhere([
       'id' => $this->id,
       'price' => $this->price,
       'reg_date' => $this->reg_date,
    ]);
    $query->andFilterWhere(['like','patient.patient_name',$this->patient_id]);

    return $dataProvider;$sum;
}

我的观看页面

<?= GridView::widget([

    'dataProvider' => $dataProvider,$sum,

    'filterModel' => $searchModel,
    'showFooter' => true,
    'columns' => [

        ['class' => 'yii\grid\SerialColumn'],

        [
        'attribute'=>'patient_id',
        'value'=>'patient.patient_name'
        ],
        'price',
        ],
        [
        'attribute' => 'sum',
        'footer' => 'sum',
        ],
        ['class' => 'yii\grid\ActionColumn'],
    ],
    ]); 
?>

显示的信息是：

设置未知属性：yii \ grid \ GridView :: 0

Answer 1

您可以使用use kartik\grid\GridView;达到相同的效果，而无需使用辅助功能。

只需将'showPageSummary' => true添加到GridView配置，将pageSummary' => true添加到需要求和的列。

查看

use kartik\grid\GridView; echo GridView::widget([ 'dataProvider' => $dataProvider, 'filterModel' => $searchModel, 'showPageSummary' => true, 'columns' => [ ['class' => 'yii\grid\SerialColumn'], [ 'attribute' => 'patient_id', 'value' => 'patient.patient_name' ], [ 'attribute' => 'price', 'pageSummary' => true ], ['class' => 'yii\grid\ActionColumn'], ], ]); ?>

Answer 2

页脚通常用于列的总结果（不是用于分隔列）

假设$sum是您想要的值，请参阅下面的列价格

 <?= GridView::widget([
  'dataProvider' => $dataProvider
  'filterModel' => $searchModel,
  'showFooter' => true,
  'columns' => [
      ['class' => 'yii\grid\SerialColumn'],
      [
        'attribute'=>'patient_id',
        'value'=>'patient.patient_name'
      ],
      [
        'attribute'=>'price',
        'footer' => $sum,       
      ],
      ['class' => 'yii\grid\ActionColumn'],
    ],
  ]); 
?>

但是看看你的代码你有几个错误..

在搜索中这是错误的

 return $dataProvider;$sum;

您只能返回一个值

  return $dataProvider;

在你的控制器中这是错误的

 $searchModel = new ReceiptsSearch();
 $sum = new ReceiptsSearch();

$ sum的结果与$ searcModel的结果相同，$ sum不返回新值

你应该以这种方式执行$ sum的查询

$sum = Receipts::find()->sum('price');



$searchModel = new ReceiptsSearch();
$sum = Receipts::find()->sum('price');
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [
  'searchModel' => $searchModel,
  'dataProvider' => $dataProvider,
   'sum'=>$sum,
  ]);

Yii2：得到总和在gridview的页脚
