如何仅使用自定义按钮更新Yii2中的一个字段，而不是全部记录？

Question

I'm really new to yii2 and looking forward to post as few questions as I can. I would like to update a data field with curdate() when a button is pressed.. but currently, pressing the button updates ALL the records:

 [
        'class' => 'kartik\grid\ActionColumn',
        'header' => 'Aggiorna',
        'template' => '{my_button}',
        'buttons' => [
            'my_button' => function ($url, $model, $key) {
             return Html::button('<span class="glyphicon glyphicon-link"> 
             </span>',
             ['value'=>Yii::$app->db
                       ->createCommand("UPDATE 
                       qual_lab_sistema_qualita_attivita SET 
                       data_ultimo_invio=CURDATE() 
                       WHERE id= '$model->id' ;")
                       ->execute(),
                       'class' => 'btn btn-default btn-xs', 
                       'id'=>'modalButtonView',
                        ]);;
            }
        ],
        'options' => [
            'width' => '20',
            ],
    ],

Can u help me pleasE? Thanks a lot

This doesn't work this way. You should send HTTP request to your controller's action for this. For example with AJAX.

[
    'class' => 'yii\grid\ActionColumn',
    'buttons' => [
        'my_button' => function ($url, $model, $key) {
            return Html::button('<span class="glyphicon glyphicon-link"></span>', [
                'onclick' => "
                    $.ajax({
                        type: 'DELETE',
                        url: '" . Url::to(['update-item', 'id' => $model->primaryKey]) . "',
                        dataType: 'json'
                    }).done(function(){alert('Updated');});
                ",
            ]);
        }
    ],
],

And create action

public function actionUpdateItem($id)
{
    \Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;

    $updatedRows = \Yii::$app->db
        ->createCommand()
        ->update('{{qual_lab_sistema_qualita_attivita }}', [
            'data_ultimo_invio' => new \yii\db\Expression("NOW()")
        ], ['id' => $id])
        ->execute();

   return [];
}
