手动应用形式错误 [英] Applying form errors manually

问题描述

我有一种情况，我在一个更大的上下文中编辑一段数据。用户将此数据提交到用于处理的特定动作，并重定向回到父页面。因为它是一个重定向，验证错误没有得到自动设置，所以我想解决这个问题。

I have a situation where I'm editing a snippet of data within a larger context. The user submits this data to a specialized action for handling and redirects back to the parent page. Because it's a redirection, validation errors aren't getting automagically set, so I'm trying to work around that.

如果发生错误，我写 $ model-> validationErrors 的会话的 validation_errors 键。在形式上，虽然，我想告诉Cake设置每个错误，所以我可以利用我现有的风格，而不必对我的 $ this-> Form-> input（）方法。

In the event of an error, I'm writing a validation_errors key to the session with a value of $model->validationErrors. In the form, though, I'd like to tell Cake to set each error so I can leverage my existing styles and not have to make a lot of changes to my $this->Form->input() methods.

这样的东西可能吗？基本上，我正在寻找手动实现相同的结果，你会得到如果一个常规表单提交并允许通过验证错误。我希望我可以循环遍历每个验证错误，并设置字段错误，但这不是任何改变。

Is something like this possible? Essentially, I'm looking to manually achieve the same result you'd get if a regular form was submitted and allowed to drop through with validation errors. I was hoping I could loop over each validation error and set the field error, but that's not making any change at all.

谢谢。

推荐答案

这可以在控制器中通过

$this->Model->invalidate('fieldName', __('ErrorMessage', true));

如果值可用，您还可以调用

If the values are available, you can also call

$this->Model->validates();

以验证模型中定义的验证器的所有值。

to validate all values with the validators defined in the model.
