使用CakePHP Auth组件的唯一用户名和电子邮件

Question

我是Cake的新手并且正在构建一个应用程序来学习它.我的用户注册系统遇到了一些麻烦.到目前为止,这是我的Users控制器中的注册码:

public function register() {
    $this->set('title_for_layout', 'Register');
    if ($this->request->is('post')) {
        $this->User->create();
        if ($this->User->save($this->request->data)) {
            $this->Session->setFlash('The user has been saved');
            $this->redirect(array('action' => 'register'));
        } else {
            $this->Session->setFlash('The user could not be saved. Please, try again.');
        }
    }
}

在我的User模型中,我有这个方法,我在哈希密码:

public function beforeSave() {
    if (isset($this->data[$this->alias]['password'])) {
        $this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['password']);
    }
    return true;
}

这很有效,用户users使用他们的用户名,电子邮件和哈希密码将用户添加到我的数据库中的表中.但是,没有进行任何检查以确保用户名和电子邮件是唯一的.

根据我的有限理解,我需要在User模型中添加一些验证规则,以确保用户名和电子邮件字段在输入表格之前是唯一的？目前我只有这些验证规则:

public $validate = array(
    'username' => array(
        'required' => array(
            'rule' => array('notEmpty'),
            'message' => 'A username is required'
        )
    ),
    'email' => array(
        'required' => array(
            'rule' => array('notEmpty'),
            'message' => 'An email is required'
        )
    ),
    'password' => array(
        'required' => array(
            'rule' => array('notEmpty'),
            'message' => 'A password is required'
        )
    )
);

此外,我的注册表有一个Password (confirm)名为的字段passwordConf.我想检查用户是否在输入用户表之前正确输入了密码,但我不知道该怎么做.我猜我的寄存器方法中的某个地方我需要检查这两个密码是否相同.

谢谢你的帮助.

isUnique规则适用于您的用户名和电子邮件字段.以下是一个代码示例,演示了如何为每个字段使用多个规则:

public $validate = array(
    'username' => array(
        'required' => array(
            'rule' => array('notEmpty'),
            'message' => 'You must enter a username.'
        ),
        'length' => array(
            'rule' => array('between', 3, 15),
            'message' => 'Your username must be between 3 and 15 characters long.'
        ),
        'unique' => array(
            'rule'    => 'isUnique',
            'message' => 'This username has already been taken.'
        )
    ),
    'password' => array(
        'required' => array(
            'rule' => array('notEmpty'),
            'message' => 'You must enter a password.'
        ),
        'length' => array(
            'rule' => array('minLength', '6'),
            'message' => 'Your password must be at least 6 characters long.'
        )
    ),
        'email' => array(
            'email' => array(
            'rule'    => array('email'),
            'message' => 'Please enter a valid email address.'
        )
    )
);

至于比较密码只需编辑你的beforeSave回调并相互检查密码,如果匹配则返回true,否则返回false.像这样的东西:

public function beforeSave() {
    if (isset($this->data[$this->alias]['password'])) {
        if($this->data[$this->alias]['password'] === $this->data[$this->alias]['passwordConf']) {
            $this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['password']);
            return true;
        } else {
            return false;
        }
    }
    return true;
}
