CakePHP保存重定向后的验证错误 [英] CakePHP preserving validation errors after redirecting

问题描述

我有一个元素显示一个注释形式，动作是comments / add。如果表单不验证，我不想让用户去评论/添加（不存在的视图），但我希望他们保持在同一页面，并看到验证错误。

I have an element which displays a comment form, the action is comments/add. If the form doesn't validate, I don't want users to go to comments/add (the view for which does not exist), but I want them to remain on the same page and see the validation errors there.

但是，重定向到$ this-> referer（）不起作用 - 验证错误消失，只剩下闪存消息。

However, redirecting to $this->referer() doesn't work - the validation errors disappear and just the flash message remains.

public function add(){
    if (!empty($this->data)){
        $this->Comment->create();
        if ($this->Comment->save($this->data)){
            $this->Session->setFlash('Comment added.','success');
            $this->redirect($this->referer());
        }else{
            $this->Session->setFlash('There was a problem adding your comment.  Please try again.','failure');
        }
    }
}

验证错误和表单数据重定向？如果这不可能，我还能如何解决问题？

How can I either retain the validation errors and form data on redirect? If this isn't possible, how else can I solve the problem?

非常感谢，
