一种流体形式的多个对象

Question

我需要用流体将两个物体放在一个形式中。背景是：我有一个 userDomain 和一个排序对象。两者都不持久。我想将这两个对象发送到一个动作而不使其中一个对象持久化。 userDomain 对象由表单处理，另一个分配给视图。如果我将排序对象添加到表单中的参数部分，Typo3 会抛出此错误：

Oops, an error occurred!

Could not serialize Domain Object Whmcs\Registration\Domain\Model\Ordering. It is neither an Entity with identity properties set, nor a Value Object.

More information regarding this error might be available online.

这是因为该对象是非持久性对象，没有任何 ID。

所以问题是，我如何将这两个对象传递给下一个动作？

Answer 1

为了在多个操作之间传递非持久对象，我建议您将序列化的对象存储在 TYPO3 会话变量中。这样做，您可以恢复目标操作中的对象。

您在下面找到一个工作示例，该示例也可以在 here.

此示例是多步骤表单验证示例的一部分，但使用 TYPO3 会话变量来存储每个表单步骤的输入。
