一个流体形式的多个对象

标签: typo3 fluid extbase

我需要将两个物体放在一个带有液体的物体中。 背景是:我有一个userDomain和一个订购对象。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其中一个持久化。 userDomain对象由表单处理,另一个对象分配给视图。如果我将排序对象添加到表单中的参数部分,Typo3会抛出这个错误:

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的,并且没有任何ID。

所以问题是,我如何将这两个对象传递给下一个动作?

1 个答案:

答案 0 :(得分:1)

为了在多个动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。

下面是一个工作示例,也可以找到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。
