Question

我使用带有多个选项的Kartik select dropDownList。

http://demos.krajee.com/widget-details/select2 我可以在循环中添加一些项目，但我无法更新项目，因为我得到了

有什么不对？

我在环路中创建新项目的控制器操作

 public function actionCreate()
{
    $model = new reservation();

    if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {
        Yii::$app->response->format = Response::FORMAT_JSON;
        return ActiveForm::validate($model);
    }
    if ($model->load(Yii::$app->request->post())) {
        foreach ($_POST['Reservation']['id_place']  as $key=> $item) {


            $model->id_reservation = NULL;
            $model->create_at = date('Y-m-d H:i:s');
            $model->auth_key = Yii::$app->security->generateRandomString();
            $model->id_place=$item;
            $model->isNewRecord = true;
            $model->save();
        }
        return $this->redirect(['view', 'id' => $model->id_reservation]);

    } else {
        $model->auth_key = Yii::$app->security->generateRandomString();
        return $this->renderAjax('create', [
            'model' => $model,

        ]);
    }
}

我的更新操作

public function actionUpdate($id)
{
    $model = $this->findModel($id);

    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        return $this->redirect(['view', 'id' => $model->id_reservation]);
    } else {
        return $this->render('update', [
            'model' => $model,
        ]);
    }
}

我的观点

echo $form->field($model, 'id_place')->widget(Select2::classname(), [

    'theme' => Select2::THEME_KRAJEE,

    'language' => 'pl',
    'options' => ['placeholder' => 'Select  place',
        'id' => 'rezerwacja',
        'multiple'=>true,

    ],
    'pluginOptions' => [
        'allowClear' => true,

    ],
])->label("Miejsce:  max (5)"); ?>

Yii2 Kartik多选列表错误array_combine（）
