我知道这个问题已经被问过很多次了，但没有一个答案能解决我的问题。首先让我展示一下我在哪里设置了 Flash 并回显 $this->Session->flash()。
这是我的添加功能：
if(!empty($this->request->data))
{
$friend_id = $this->request->data['User']['id'];
$user_id = $this->Auth->User('id');
$already_friends = $this->Group->findByIdAndFriend($user_id, $friend_id);
if($already_friends)
{
$this->Session->setFlash(__('You are already friends', true));
}
else
{
$this->Group->create();
$data = array($user_id, $friend_id);
if($this->Group->save($data))
{
$this->Session->setFlash(__('You are now friends', true));
}
else {
$this->Session->setFlash(__('Failed to add friend. Please try again', true));
}
}
$this->redirect(array('action' => 'index'));
这是我的布局，它的必要部分：
<div id="header">
<?php echo $this->Html->image('connect.jpg', array('alt' => 'My Image', 'id' => 'headerImage')) ?>
<div id="headerNavMenu">
<div name="navTab" class="menuTab">
<?php echo $this->Html->link('Me', array('controller' => 'users', 'action' => 'view', CakeSession::read("Auth.User.id")), array('class' => 'tabName')) ?>
</div>
<div name="navTab" class="menuTab">
<?php echo $this->Html->link('My Schedule', array('controller' => 'newSchedules', 'action' => 'index'), array('class' => 'tabName')) ?>
</div>
<div name="navTab" class="menuTab">
<?php echo $this->Html->link('My Group', array('controller' => 'groups', 'action' => 'index'), array('class' => 'tabName')) ?>
</div>
<div name="navTab" class="menuTab">
<a href="#" class="tabName">Settings</a>
</div>
</div>
<div id="login">
<?php echo CakeSession::read("Auth.User.firstName").' '.CakeSession::read("Auth.User.lastName").' ' ?>
<?php echo $this->Html->link('logout', array('controller' => 'users', 'action' => 'logout')) ?>
</div>
</div>
<div id="mainContent">
<?php echo $this->Session->flash(); ?>
<?php echo $this->Session->flash('auth'); ?>
<?php echo $this->fetch('content') ?>
</div>
</div>
除了没有显示闪烁消息的事实之外，似乎也没有检查模型的验证标准，因为特定消息也没有显示。
我是 cakePHP 的新手，但我一直在关注博客教程来完成我的大部分工作。闪存消息过去可以工作，但现在它甚至不适用于以前的模型。
这是我的验证：
public $validate = array(
'first_name' => array(
'required' => array(
'rule' => array('notempty'),
'message' => 'First Name cannot be blank',
'allowEmpty' => false,
'required' => true
)
),
'last_name' => array(
'required' => array(
'rule' => array('notempty'),
'message' => 'Last Name cannot be blank',
'allowEmpty' => false,
'required' => true
)
),
'email' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'Email cannot be blank',
'allowEmpty' => false,
'required' => true
),
'valid' => array(
'rule' => array('email', true),
'message' => 'This is not a valid email',
'required' => true
),
'unique' => array(
'rule' => array('isUnique'),
'message' => 'This email already exists',
'required' => true
)
),
'password' => array(
'required' => array(
'rule' => array('notempty'),
'message' => 'Password cannot be blank',
'allowEmpty' => false,
'required' => true
),
'valid' => array(
'rule' => array('minlength', 6),
'message' => 'Password has to be at least 6 characters',
'required' => true
),
'password_has_to_be_alphanumeric' => array(
'rule' => 'alphanumeric',
'message' => 'Password has to be alphanumeric',
'required' => true
)
)
);
