Yii2 gridview sum of column value

Here is some of the sample code to get the sum of the column values in the footer in the gridview. It was 100% working in the gridview in Yii2.

All you need to change is the values

 [
   'label' => 'cost',
   'attribute' => 'cost',
   'value' => function ($model, $key, $index, $widget) {
                            return $model->cost;
                    },
   'footer' => $cost,
 ],

The above code should be added in the gridview with footer enabled.

'showFooter' =>true,

Here cost the value which need to be totaled, so you need to change according to your needs. You also need to add the below code in the view page.

<?php
$cost = 0;
if (!empty($dataProvider->getModels())) {
 foreach ($dataProvider->getModels() as $key => $val) {
     $cost += $val->cost;
    }
}
?>

Use this code and calculate sum of values in the footer in the Yii2 Gridview.
