# UsersController.PHP
public function edIT() {
    if($this->request->is('post')) {
        if($this->User->save($this->request->data)) {
            $this->Session->setFlash('Your account has been updated.');
            $this->redirect(array('action' => 'edit'));
        }

        $this->Session->setFlash('There was a PRoblem saving your account settings. Please try again.');
    }

    // Auto populate form fields
    if(!$this->request->data) {
        $this->request->data = $this->User->find('First',array(
            'conditions' => array('User.id' => $this->Auth->user('id'))
        ));
    }
}

# edit.ctp
<?PHP echo $this->Form->create('User'); ?>
<?PHP echo $this->Form->input('currentPassword',array('between' => 'You must enter your password in order to make changes','tyPE' => 'password','value' => '','autocomplete' => 'off')); ?>
<?PHP echo $this->Form->input('email'); ?>
<?PHP echo $this->Form->input('password',array('type' => 'password','between' => 'Must be atleast 6 characters','autocomplete' => 'off')); ?>
<?PHP echo $this->Form->input('confirmPassword','autocomplete' => 'off')); ?>
<?PHP echo $this->Form->end('Save changes'); ?>

现在,我想让用户输入他们当前的密码以进行更改.为了使其工作,我需要运行验证检查以确保他们在currentPassword中输入的密码与我在数据库中的密码相匹配.我的用户模型中的一个@R_777_1851@是：

'currentPassword' => array(
    'custom' => array(
        'rule' => 'validateCurrentPassword','message' => 'Incorrect password. Make sure you\'re using your current password.'
    )
),

以及被调用的相关函数：

public function validateCurrentPassword($data) {
    debug($data);
    return false;
}

到目前为止一切都那么好,但有一些非常奇怪的行为.在两次页面加载后,Cake似乎只验证此字段.例如,如果输入错误的值并按“保存更改”,页面将刷新,但不会弹出验证错误.如果我输入另一个错误的值,我会收到验证错误.出于某种原因,我需要提交表格两次以进行验证.

任何人都可以找出原因吗？
