Yii2 Gridview - 如何在页脚属性上使用总计

Question

我的VALUE列是:

    [
     'attribute' => 'value',
     'format' => 'raw',
     'contentOptions'=>['style'=>'width: 10%;text-align:left'],
     'footer' => ???
    ],

如何在FOOTER属性上使用行总数？

Answer 1

它的工作原理1.创建类然后2.create列数组,3.configure列,4.configure grid

namespace app\components;
class PTotal {
public static function pageTotal($provider, $fieldName)
{
    $total=0;
    foreach($provider as $item){
        $total+=$item[$fieldName];
    }
    return $total;
}
$provider = new ActiveDataProvider([
'query' => $query,
'sort' => $sort,
]);


$grid_columns=[         
[
    'attribute' => 'saldo_in',
    'footer'=>PTotal::pageTotal($provider->models,'saldo_in'),
]
]

echo GridView::widget([
'dataProvider' => $provider,
'showFooter'=>TRUE,
'footerRowOptions'=>['style'=>'font-weight:bold;text-decoration: underline;'],
'columns' =>$grid_columns,
]);
