Question

自最新版本的Phalcon发布以来，文档中提供的示例似乎无法正常工作。

首先，我使用phalcon model User在命令行创建一个DevTools的新模型。

然后，我修改了validation()函数。我的models\User.php文件：

use Phalcon\Mvc\Model\Validator\Email as Email;
use Phalcon\Mvc\Model\Validator\Uniqueness as Uniqueness;
use Phalcon\Mvc\Model\Validator\StringLength as StringLength;

class User extends \Phalcon\Mvc\Model
{
    public function validation()
    {
        $this->validate(
            new Email(
                array(
                    'field' => 'email',
                    'message' => 'Please enter a valid email'
                )
            )
        );

        $this->validate(
            new Uniqueness(
                array(
                    'field' => 'email',
                    'message' => 'Your email is already in use'
                )
            )
        );

        $this->validate(
            new StringLength(
                array(
                    'field' => 'password',
                    'min' => 4,
                    'max' => 30,
                    'minMessage' => 'Your password must be at least 4 characters',
                    'maxMessage' => 'Your password must be less than 30 characters'
                )
            )
        );

        if ($this->validationHasFailed() == true) {
            return false;
        }

        return true;
    }
}

但是，这会引发以下错误：

可捕获致命错误：参数1传递给Phalcon \ Mvc \ Model :: validate（）必须实现接口Phalcon \ ValidationInterface，Phalcon \ Mvc \ Model \ Validator \ Email实例 C：\ xampp \ htdocs \ app \ models \ User.php 在线 27

这是什么意思？我相信Phalcon\Validation和Phalcon\Mvc\Model\Validator是完全不同的野兽（后者提供更多功能）？

截至Phalcon 3.0 Phalcon\Mvc\Model\Validation现已弃用，Phalcon\Validation。这样做是为了减少代码库，因为两个组件都在做类似的工作。您可以在下面找到需要更改的示例。

旧路：

namespace Invo\Models;

use Phalcon\Mvc\Model;
use Phalcon\Mvc\Model\Validator\Email as EmailValidator;
use Phalcon\Mvc\Model\Validator\Uniqueness as UniquenessValidator;

class Users extends Model
{
    public function validation()
    {
        $this->validate(
            new EmailValidator(
                [
                    'field' => 'email',
                ]
            )
        );

        $this->validate(
            new UniquenessValidator(
                [
                    'field'   => 'username',
                    'message' => 'Sorry, That username is already taken',
                ]
            )
        );

        if ($this->validationHasFailed() == true) {
            return false;
        }
    }
}

新方式：

namespace Invo\Models;

use Phalcon\Mvc\Model;
use Phalcon\Validation;
use Phalcon\Validation\Validator\Email as EmailValidator;
use Phalcon\Validation\Validator\Uniqueness as UniquenessValidator;

class Users extends Model
{
    public function validation()
    {
        $validator = new Validation();

        $validator->add(
            'email', //your field name
            new EmailValidator([
                'model' => $this,
                'message' => 'Please enter a correct email address'
            ])
        );

        $validator->add(
            'username',
            new UniquenessValidator([
                'model' => $this,
                'message' => 'Sorry, That username is already taken',
            ])
        );

        return $this->validate($validator);
    }
}
