Phalcon 3：使用\\ Phalcon \\ Mvc \\ Model \\ Validator驗證表單數據

Question

自從最新版本的Phalcon發布以來，文檔中提供的示例似乎無法正常工作。

首先，我創建一個新的模式DevTools使用在命令行phalcon model User 。

然后，我修改了validation()函數。 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，這會引發以下錯誤：

可捕獲的致命錯誤：傳遞給Phalcon \\ Mvc \\ Model :: validate（）的參數1必須實現接口Phalcon \\ ValidationInterface，在C：\\ xampp \\ htdocs \\ app \\ models \\ User中給出的Phalcon \\ Mvc \\ Model \\ Validator \\ Email實例第27行的.php

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

截至Phalcon 3.0 Phalcon\\Mvc\\Model\\Validation現已棄用，以支持Phalcon\\Validation 。 這樣做是為了減少代碼庫，因為兩個組件都在做類似的工作。 您可以在下面找到需要更改的示例。

舊方式：

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;
        }
    }
}

新方法：

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);
    }
}
