在頁面提交後向Symfony2表單集合類型添加其他項目

我有一個建立在購買想法上的表單。它有購買物品，付款金額和付款方式（VISA，萬事達卡，現金）。我已經預先填寫了2個購買物品的表單，但是如果用戶選擇卡支付類型（VISA或萬事達卡）類型，我正在嘗試添加其他購買物品。這個額外的購買項目，我想通過控制器添加。在頁面提交後向Symfony2表單集合類型添加其他項目

Rendered Form view

真正的問題是，我在哪裏實現控制器動作這個功能......或者是更好，因爲在表單類型的事件監聽？

當形式與附加卡工本費購買項目我碰到下面的錯誤...

沒有看到PurchaseItem.php？ – Fiemhong

發生這種情況的原因是默認選項data_class調用不帶參數的構造函數那個。如果您Aazp\Booking Bundle\Entity\PurchaseItem類在構造函數的參數，你需要使用empty_data選項實例：

// Aazp\BookingBundle\Form\PurchaseItemType.php 

$resolver->setDefaults([ 
    'empty_data' => function (FormInterface $form) { 
     return new PurchaseItem($form->get('product')->getData()); 
    }, 
]);

您可以更多瞭解此選項here。

甚至沒有看這許多謝謝Yonel。我認爲異常指的是Purchase Item代理實體或在表單初始預加載後創建的新實體。根據例外情況，我認爲他們沒有關聯的產品。因此，這固定了我的問題的第一部分，現在我已經設法修復其餘部分。現在我希望這只是簡單的邏輯來實現，然後完成。再次感謝Yonel，你讓我再次前進。（y）的 – tmschneider
