如何在cakephp 3中闪烁不同窗体动作字段验证错误消息

我有一个视图,其中有两个表单。一个用于登录,另一个用于注册。对于注册操作,我使用了操作

Users/add

我在我的 login.ctp 喜欢

<?= $this->Form->create($user, ['url' => ['action' => 'add']]); ?>

在add action I中编写的代码

public function add()
    {
        $user = $this->Users->newEntity();
        if ($this->request->is('post')) {
            $user = $this->Users->patchEntity($user, $this->request->getData());
            if ($this->Users->save($user)) {
                $this->Flash->success(__('The user has been saved.'));
                return $this->redirect(['action' => 'login']);
            }else{

                $this->Flash->error(__('The user could not be saved. Please, try again.'));
                return $this->redirect(['action' => 'login']);
            } 
        }
        $this->set(compact('user'));
    }

现在,如果我犯了任何验证错误,例如密码匹配验证错误,则此错误不会显示在字段下 password . 但我可以从add中看到它。ctp。

如何将此验证错误消息从添加操作发送到登录操作?
