Cakephp 如何接收注册用户的确认码？

我正在应用本教程：

当我提交邮件时，它是这样发送的：

嘿，艾哈迈德，我们会让你立即启动并运行，但首先我们只需要你点击下面的链接确认你的用户帐户：

http://localhost/cakenews/users/activate/24/8877ae4a

问题是我想创建文件users/active.ctp，以便在用户单击链接时接收激活码。但是我不知道要给活跃用户写什么

<?php
# /controllers/users_controller.php
# please note that not all code is shown...
uses('sanitize');
class UsersController extends AppController {
    var $name = 'Users';
    // Include the Email Component so we can send some out :)
    var $components = array('Email', 'Auth');

    // Allow users to access the following action when not logged in
    function beforeFilter() {
        $this->Auth->allow('register', 'confirm', 'logout');
        $this->Auth->autoRedirect = false;
    }

    // Allows a user to sign up for a new account
    function register() {
        if (!empty($this->data)) {
            // See my previous post if this is forgien to you
 $this->data['User']['password'] = $this->Auth->password($this->data['User']['passwrd']);
            $this->User->data = Sanitize::clean($this->data);
            // Successfully created account - send activation email
            if ($this->User->save()) {
                $this->__sendActivationEmail($this->User->getLastInsertID());

                // this view is not show / listed - use your imagination and inform
                // users that an activation email has been sent out to them.
                $this->redirect('/users/register');
            }
            // Failed, clear password field
            else {
                $this->data['User']['passwrd'] = null;
            }
        }
    }

    function __sendActivationEmail($user_id) {
        $user = $this->User->find(array('User.id' => $user_id), array('User.id','User.email', 'User.username'), null, false);
        if ($user === false) {
            debug(__METHOD__." failed to retrieve User data for user.id: {$user_id}");
            return false;
        }

        // Set data for the "view" of the Email

        $this->set('activate_url', 'http://' . env('SERVER_NAME') . '/cakenews/users/activate/' . $user['User']['id'] . '/' . $this->User->getActivationHash());
  $this->set('username', $this->data['User']['username']);

        $this->Email->to = $user['User']['email'];
        $this->Email->subject = env('SERVER_NAME') . ' - Please confirm your email address';
        $this->Email->from = 'email@gmail.com';
        $this->Email->template = 'user_confirm';

        $this->Email->sendAs = 'text';   // you probably want to use both :)
        return $this->Email->send();
    }
}


/**

function activate($user_id = null, $in_hash = null) {
    $this->User->id = $user_id;
    if ($this->User->exists() && ($in_hash == $this->User->getActivationHash()))
    {
        // Update the active flag in the database
        $this->User->saveField('active', 1);

        // Let the user know they can now log in!
        $this->Session->setFlash('Your account has been activated, please log in below');
        $this->redirect('login');
    }

    // Activation failed, render '/views/user/activate.ctp' which should tell the user.
}

视图为cakenews\app\views\users\register.ctp

    <fieldset>
        <legend>Add a article</legend>
<?php
echo $form->create('User');
echo $form->input('username');
echo $form->input('password');
echo $form->input('email');
?>
    </fieldset>
   <?php echo $form->end('Post project');   ?>

在控制器操作中，

激活

正在处理用户激活。如果用户被验证，它将重定向到登录操作，否则它将尝试呈现

activate.ctp

文件。因此，在这种情况下，您可以向用户显示一条消息，说明您的注册无法完成。请再试一次。要为视图（activate.ctp）设置一些数据，可以使用控制器的set方法

---

如果您根本不想呈现activate.ctp文件，请将用户重定向到其他地方，告知注册无法完成。

当我单击链接时，我在UsersController中看到此消息缺少方法错误：在controller UsersController中未定义activate操作错误为((（UsersController错误中缺少方法：未在控制器UsersController错误中定义激活操作：在文件：app\controllers\users\u controller.中创建UsersController:：activate（））单击链接时，我看到以下消息：UsersController错误中缺少方法：控制器UsersController中未定义操作激活错误是（（（UsersController错误中缺少方法：控制器UsersController错误中未定义操作激活：创建UsersController:：activate（）文件中：app\controllers\users\u controller.））
