我的项目中有一个用户管理器。当我添加用户所有的验证必须调用，但根据我的要求，当我的电子邮件&密码从用户登录，然后我希望是唯一的验证的电子邮件地址不被调用。
UserController.php
public function login() {
$this->layout = 'login';
if ($this->request->is('post')) {
/** these conditions are used to call validations forcefully **/
if (!empty($this->request->data)) {
$this->User->set($this->request->data);
if($this->User->validates()) {
}
} else {
$errors = $this->User->invalidFields();
}
if ($this->Auth->login()) {
return $this->redirect($this->Auth->redirectUrl());
} else {
//$errors = "Invalid email or password, try again";
$this->Session->setFlash(__('Invalid email or password, try again'));
}
}
}
User.php
public $validate = array(
'email' => array(
'required' => array(
'rule' => 'notEmpty',
'message' => 'A email is required.'
),
'email' => array(
'rule' => array('email', true),
'message' => 'Please fill a valid email address.'
),
'isUnique' => array(
'rule' => array('isUnique'),
'message' => 'This email id already exist.'
)
),
'password' => array(
'rule' => 'notEmpty',
'message' => 'Please enter password.'
)
);
但是当我登录时，它显示"这个电子邮件id已经存在。"消息为正确的电子邮件地址，但我想跳过这个验证，如果电子邮件id存在于数据库
您可以使用beforeValidate()(手动)回调，每次在验证之前触发，并与您将在登录方法中设置的某种标志混合使用。
所以在你的模型中添加标志字段:
protected $skipEmailUniqueValidation = false;
然后为它添加setter:
public function setSkipEmailUniqueValidation($value = true) {
$this->skipEmailUniqueValidation = $value;
}
并添加beforeValide()方法:
public beforeValidate(array $options = array()) {
if ($this->skipEmailUniqueValidation) {
unset($this->validate['email']['isUnique']);
}
return parent::beforeValidate($options);
}
最后要做的是设置skipEmailUniqueValidation在您的动作:
public function login() {
$this->layout = 'login';
if ($this->request->is('post')) {
/** these conditions are used to call validations forcefully **/
if (!empty($this->request->data)) {
$this->User->set($this->request->data);
$this->User->setSkipEmailUniqueValidation(true); // here
if($this->User->validates()) {
}
} else {
$errors = $this->User->invalidFields();
}
if ($this->Auth->login()) {
return $this->redirect($this->Auth->redirectUrl());
} else {
//$errors = "Invalid email or password, try again";
$this->Session->setFlash(__('Invalid email or password, try again'));
}
}
}
