cakephp自定义验证规则消息

Question

我有一个自定义验证规则来检查输入的两个密码是否相同,如果它们不是,我希望有一条消息"密码不匹配".

但是,规则有效,当密码不匹配时,只显示正常的错误消息,发生了什么？

var $validate=array(
        'passwd2' => array('rule' => 'alphanumeric',
                        'rule' => 'confirmPassword',
                        'required' => true,
                        'allowEmpty'=>false));

function confirmPassword($data)
{
    $valid = false;
    if ( Security::hash(Configure::read('Security.salt') .$data['passwd2']) == $this->data['User']['passwd'])
    {
        $valid = true;
        $this->invalidate('passwd2', 'Passwords do not match');
    }
    return $valid;
}

它说"这个字段不能留空"

编辑:

奇怪的是,如果我将其中一个密码字段留空,则两条错误消息都会显示"此字段不能留空"

但是,如果我在两者中放入某些东西,那么它正确地说"密码不匹配"

我觉得你太复杂了.我是这样做的:

    // In the model
    public $validate = array(
        'password' => array(
            'minLength' => array(
                'rule' => array('minLength', '8')
            ),
            'notEmpty' => array(
                'rule' => 'notEmpty',
                'required' => true
            )
        ),
        'confirm_password' => array(
            'minLength' => array(
                'rule' => array('minLength', '8'),
                'required' => true
            ),
            'notEmpty' => array(
                'rule' => 'notEmpty'
            ),
            'comparePasswords' => array(
                'rule' => 'comparePasswords' // Protected function below
            ),
        )
    );
    protected function comparePasswords($field = null){
        return (Security::hash($field['confirm_password'], null, true) === $this->data['User']['password']);
    }

// In the view
echo $form->input('confirm_password', array(
    'label' => __('Password', true),
    'type' => 'password',
    'error' => array(
        'comparePasswords' => __('Typed passwords did not match.', true),
        'minLength' => __('The password should be at least 8 characters long.', true),
        'notEmpty' => __('The password must not be empty.', true)
    )
));
echo $form->input('password', array(
    'label' => __('Repeat Password', true)
));
