我们如何为模型对象键（即数组）分配值

Question

I am using Yii2 with ActiveFrom . I have form of user which add multiple names, email etc.

For example:

echo $form->field($model, "name[$i]")->widget(kartik\select2\Select2::classname(), [
                                    'data' => $name_master,
                                    'options' => ['placeholder' => 'Select drop down', 'multiple' => false, 'class' => 'selectpicker form-control'],
                                ])->label(false);

I am able to save the value at the time of adding it. But when I try to open it in edit form and assign value to model key I am getting error.

Assign value to key for edit mode.

foreach ($namesDump as $val) {
    $objectKey = "name";
    $model->$objectKey[$index] = $val['name'];
}

It is give me error can someone tell me how we can assign value to object key which is array form.

您可能应该使用{}来表示属性名称的优先级-根据PHP版本的不同，它是不同的：

$model->{$objectKey}[$index] = $val['name'];
