Yii2：提交具有两个相同模型实例的表单验证

Question

跟进：Yii2: Validation in form with two instances of same model

我有一个型号Booking，其字段为shipping_address和billing_address，两个型号的地址。我现在想要将它们打印到基本上工作得很好的相同形式。验证适用于使用数据填充字段，但在提交表单时失败。

在控制器中，帐单地址使用现有地址模型的字段设置，并且发货地址使用新的地址模型设置：

 public function actionCreate()
{

    $model = new Donation();

    if (!empty($_POST['Address'])) {

        //TODO: Save models

        return $this->redirect(['view', 'id' => $model->id]);

    } else {

        $user = User::find(Yii::$app->user->identity->id)->one();
        $billing_address = $user->getBillingAddress()->one();

        return $this->render('create', [
            'model' => $model,
            'billing_address' => $billing_address,
            'shipping_address' => new Address()
        ]);
    }
}

以下代码显示了字段的打印方式。

比林兹字段：

<?= $form->field(
        $billing_address,
        'address_line_1',
        [
            'selectors' => [
                'input' => '#billing-address_line_1',
                'error' => '#billing-address_line_1',
                'container' => '.billing-address_line_1'
            ],
            'options' =>
                ['class' => 'billing-address_line_1']
        ])->textInput([
            'maxlength' => 45,
            'name'=> 'Billing_Address[address_line1]',
            'id'=>'billing-address_line_1',
    ]); ?>

优惠字段：

<?= $form->field(
        $shipping_address,
        'address_line_1',
        [
            'selectors' => [
                'input' => '#shipping-address_line_1',
                'error' => '#shipping-address_line_1',
                'container' => '.shipping-address_line_1'
            ],
            'options' =>
                ['class' => 'shipping-address_line_1']
        ])->textInput([
                'maxlength' => 45,
                'name'=> 'Shipping_Address[address_line1]',
                'id'=>'shipping-address_line_1',
    ]); ?>

如下面的屏幕截图所示，验证可以填写表格：

现在的问题 - 当我点击创建按钮时它不起作用：

关于如何解决这个问题的任何想法？填写验证和点击按钮验证有什么区别？

我会这样做，我不会直接在渲染函数中创建第二个地址，而是创建第一个模型，然后传递给函数。

 } else {

      $user = User::find(Yii::$app->user->identity->id)->one();
      $billing_address = $user->getBillingAddress()->one();
      $shipping_address = new Address();


      return $this->render('create', [
          'model' => $model,
          'billing_address' => $billing_address,
          'shipping_address' => $shipping_address,
      ]);
  }
