问题描述
我已经看到这个问题在这里很多，但我找不到任何满意的答案，所以我会尝试把它有点不同：
I have seen this problem mentioned a lot here, but I couldn't find any satisfactory answer, so I'll try to formulate it a bit differently:
我有一个登录表单和一个注册表单用于同一页面上的用户（我们称之为首页）。
I have a login form and a registration form for users on the same page (let's call it the "frontpage").
每种表单都会导致不同的控制器操作。验证后，cakephp试图显示用户/登录和用户/注册视图中的验证错误，但我没有，我不想那些视图，所以我被迫做一个重定向回到我的首页。但是，在重定向时，验证数据丢失。
Each form leads to a different controller action. Upon validation, cakephp is trying to display the validation errors in the users/login and users/register Views, but I don't have and I don't want those Views, so I'm forced to do a redirect back to my "frontpage". However, upon redirecting, the validation data is lost.
如何保持验证数据显示在我的首页，而不必为登录和注册功能添加单独的页面？
How do I go about keeping the validation data to be displayed on my frontpage, without having to add separate pages for the login and register functions?
推荐答案
Cakephp在
$this->ModelName->invalidFields();
如果你想让它持久化，我相信你必须把它保存在一个会话变量。
If you want it to behave persisten the i believe you will have to keep it in a session variable. i.e if your redirects are loosing the property value then try keeping it in a session variable.
更新：
如果您的重定向失去了属性值，请尝试将其保存在会话变量中。 invalidFields 会再次执行整个验证过程，而应改用 $ this-> ModelName-> validationErrors 。
invalidFields executes the whole validation process again and $this->ModelName->validationErrors should be used instead.
