Symnedi/Validator

This package is deprecated. Use Kdyby/Validator instead., _(*1)

, _(*2)

Install

Via Composer:, _(*3)

$ composer require symnedi/validator

extensions:
    - Symnedi\Validator\DI\ValidatorExtension
    - Kdyby\Annotations\DI\AnnotationsExtension

Usage

Let's register user, but only while having valid email., _(*5)

First, use validation annotations on entity (object) you want to validate., _(*6)

use Symfony\Component\Validator\Constraints as Assert;


class User
{

    /**
     * @Assert\NotBlank
     * @Assert\Email
     */
    private $email;


    /**
     * @var string $email
     */
    public function __construct($email)
    {
        $this->email = $email;
    }

}

Then validate in our service:, _(*7)

use Symfony\Component\Validator\Validator\ValidatorInterface;


class RegistrationManager
{

    /**
     * @var ValidatorInterface
     */
    private $validator;


    public function __construct(ValidatorInterface $validator)
    {
        $this->validator = $validator;
    }


    /**
     * Instance is passed: $user = new User('invalid.email');
     */
    public function registerUser(User $user)
    {
        $violations = $this->validator->validate($user);

        // process violations
        $violation = $violations[0];
        $violation->getMessage(); // 'Email is not valid.'
    }

}

That's it!, _(*8)
