我需要用流体将两个物体放在一种形式中。 背景是：我有一个 userDomain 和一个 ordering 对象。两者都不是持久的。我想将这两个对象发送到一个动作而不使它们中的一个持久化。 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.
这是因为对象是非持久的，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？
【问题讨论】：
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。
您可以在下面找到一个工作示例，也可以在 here 找到。

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。
