在cake php中验证规则

Question

我正在尝试在提交上验证表单，但它无效并且表单提交没有错误。视图中不显示任何消息。 我在用户模型

中使用了下面提到的代码

public $validate = array(
        'fname' => array( 
            'required' => array(
                    'rule' => array('notEmpty'),
                     'message' => 'A username is required'
            ),
            'between' => array(
                'rule'    => array('between', 3, 15),
                'message' => 'Between 5 to 15 characters'
            ),
        ),
        'email' => array('email' => array(
                'rule' => 'email',
                'message' => 'Email must be a valid email address!'
            ),
            'unique' => array(
                'rule' => 'isUnique',
                'message' => 'User already registered!'
            )
        ),
        'password' => array(
            'required' => array(
                'rule' => array('notEmpty'),
                'message' => 'A password is required'
            ),
            'between' => array(
                'rule'    => array('between', 8, 15),
                'message' => 'Between 8 to 15 characters'
            ),
            'slug' => array(
                'rule' => '/^[a-z0-9A-Z@#_]{8,}$/i',
                'message' => 'Only letters, integers ,@, # and Underscore(_), min 8 characters'
            ),
        ),
    );

UsersController.php

class UsersController extends AppController {
    public $name = 'Users';

    public function register(){
    if(($this->request->is('post'))||($this->request->is('post'))){ 
    $this->User->create();
    $this->User->save($this->request);   
    }
}
