Phalcon 3:使用\ Phalcon\Mvc\Model\Validator验证表单数据

Question

自从最新版本的Phalcon发布以来,文档中提供的示例似乎无法正常工作.

首先,我在命令行使用DevTools创建一个新模型phalcon model User.

然后,我修改了这个validation()功能.我的models\User.php档案:

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:

可捕获的致命错误:传递给Phalcon\Mvc\Model :: validate()的参数1必须实现接口Phalcon\ValidationInterface,在C:\ xampp\htdocs\app\models\User中给出的Phalcon\Mvc\Model\Validator\Email实例第27行的.php

这是什么意思？我相信Phalcon\Validation并且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现在已被弃用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);
    }
}
