php - 我如何使用 CakePHP 的模型验证消息而不是 Controller 的 setFlash 消息？

Question

描述

我网站的每个页面上都有一个简单的表单 - 一个输入和一个提交按钮。重点只是让用户输入他/她的电子邮件地址并点击提交。

如果数据是电子邮件地址，它会起作用 - 但如果它不是有效的电子邮件地址，它会提交表单，重新加载页面(或其他任何内容)，然后出现闪存消息而不是我的模型更具体的“not a有效的电子邮件”错误。

问题:

那么，我该如何使用模型的验证消息而不是 Controller 的通用验证消息呢？

形式:

echo $this->Form->create('Email', array('class'=>'form1', 'url'=>'/emails/add', 'inputDefaults'=>array('label'=>false))); 
echo $this->Form->input('Email.email');
echo $this->Form->end('SIGN-UP');

电子邮件 Controller “添加”功能(或方法？):

function add() {
    if (!empty($this->data)) {
        $this->Email->create();
        if ($this->Email->save($this->data)) {
            $this->Session->setFlash(__('The email address has been saved', true));
            $this->redirect($this->referer());
        } else {
            $this->Session->setFlash(__('The email address could not be saved. Please, try again.', true));
            $this->set('error', 'custom error here');
            $this->redirect($this->referer());
        }
    }
}

和电子邮件模型:

class Email extends AppModel {
var $name = 'Email';

var $validate = array(
    'email'     => array(
        'is_valid'  => array( //named whatever we want
            'rule'      => 'notEmpty',
                'rule'      => array('email', true),
                'message'   => 'Please supply a valid email address.',
                'last'      => true //causes it to not check the next rule if this one fails
        ),
        'is_unique'     => array( //named whatever we want
            'rule'          => 'isUnique',
            'message'       => 'That email address is already in our database.'
        )
    ),
);
}

CakePHP 会为您做这件事，您已经正确设置了验证，如果保存失败，则错误是 REDIRECT。这会丢失发布数据，从而丢失验证消息

简单

if ($this->Email->save($this->data)) {
  $this->Session->setFlash(__('The email address has been saved', true));
  $this->redirect($this->referer());
} else {
   $this->Session->setFlash(__('There were problems saving, please see the messages below.', true));                    
}
