【问题描述】：
我正在尝试使用模型中的 $validate 数组显示自定义消息，例如“此字段不应为空”或“名称不为空”。我有两个控制器，主要和用户。
主控制器的索引文件有登录和注册视图。登录和注册功能的操作部分在 user_controller 中。如果登录和注册功能生效，它们将被重定向到主控制器的主页，否则它们将保留在索引页面本身。
我希望在索引页本身中显示验证消息。但这些消息只有在存在单独的登录和注册视图文件时才会出现，即 /views/forms/register.ctp 和 /views/forms/login.ctp 存在。
有没有一种方法可以显示这些验证消息，而无需为这些功能提供单独的视图文件？我在下面给出了我的代码。请有人指导我。
模型类：
<?php
class User extends AppModel {
var $name = 'User';
var $components=array('Auth');
var $validate = array(
'name' => array(
'rule' => 'notEmpty',
'message' =>'Name cannot be null.'
),
'password' => array(
'rule' => 'notEmpty'
),
'email_id' => array(
'rule' => 'notEmpty'
)
);
function registerUser($data)
{
if (!empty($data))
{
$this->data['User']['name']=$data['User']['name'];
$this->data['User']['email_id']=$data['User']['email_id'];
$this->data['User']['password']=$data['User']['password'];
$existingUsers= $this->find('all');
foreach($existingUsers as $existingUser):
if($this->data['User']['email_id']==$existingUser['User']['email_id']){
return 0;
}
else{
$this->save($this->data);
$this->data['User']['id']= $this->find('all',array('fields' => array('User.id'),
'order' => 'User.id DESC'
));
$userId=$this->data['User']['id'][0]['User']['id'];
return $userId;
}
endforeach;
}
}
function loginUser($data)
{
$this->data['User']['email_id']=$data['User']['email_id'];
$this->data['User']['password']=$data['User']['password'];
$login=$this->find('all');
foreach($login as $form):
if($this->data['User']['email_id']==$form['User']['email_id'] && $this->data['User']['password']==$form['User']['password'])
{
$this->data['User']['id']= $this->find('all',array('fields' => array('User.id'),
'conditions'=>array('User.email_id'=> $this->data['User']['email_id'],'User.password'=>$this->data['User']['password'])
));
$userId=$this->data['User']['id'][0]['User']['id'];
return $userId;
}
endforeach;
}
}
?>
控制器类：
<?php
class UsersController extends AppController
{
var $name = 'Users';
var $uses=array('Form','User','Attribute','Result');
var $helpers=array('Html','Ajax','Javascript','Form');
function register()
{
$this->Session->write('userId',$this->User->registerUser($this->data));
$this->User->data=$this->data;
if (!$this->User->validates())
{
$this->Session->setFlash('Please enter valid inputs');
$this->redirect('/main' );
return;
}
if($this->Session->read('userId')==0){
$this->Session->setFlash('You are already a registerd member.Log in your account');
$this->redirect('/main');
}
else{
$this->Session->setFlash('User account created');
$this->redirect('/main/home');
}
}
function login()
{
//$userId=$this->User->loginUser($this->data);
$this->Session->write('userId',$this->User->loginUser($this->data));
$this->User->data=$this->data;
if (!$this->User->validates())
{
$this->Session->setFlash('Please enter valid inputs');
$this->redirect('/main' );
return;
}
if($this->Session->read('userId')>0){
$this->Session->setFlash('Login Successful');
$this->redirect('/main/home');
break;
}
else{
$this->Session->setFlash('Username and password do not match.');
$this->redirect('/main');
}
}
}
?>
查看模板：
<!-- File: /views/main/index.ctp-->
<div id="register">
<h3>Register</h3>
<?php
echo $form->create('User',array('action'=>'register'));
echo $form->input('name');
echo $form->input('email_id');
echo $form->input('password');
echo $form->end('Register');
?>
</div>
<div id="login">
<h3>Login</h3>
<?php
echo $form->create('User',array('action'=>'login'));
echo $form->input('email_id');
echo $form->input('password');
echo $form->end('Login');
?>
</div>
