Annotations

// src/AppBundle/Entity/Author.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Author
{
    /**
     * @Assert\Email(
     *     message = "The email '{{ value }}' is not a valid email.",
     *     checkMX = true
     * )
     */
     protected $email;
}

YAML

# src/AppBundle/Resources/config/validation.yml
AppBundle\Entity\Author:
    properties:

PHP

// src/AppBundle/Entity/Author.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Mapping\ClassMetadata;
use Symfony\Component\Validator\Constraints as Assert;

class Author
{
    public static function loadValidatorMetadata(ClassMetadata $metadata)
    {
        $metadata->addPropertyConstraint('email', new Assert\Email(array(
            'message' => 'The email "{{ value }}" is not a valid email.',
            'checkMX' => true,
        )));
    }
}

Options¶

strict¶

type: boolean default: false

When false, the email will be validated against a simple regular expression. If true, then the egulias/email-validator library is required to perform an RFC compliant validation.

message¶

type: string default: This value is not a valid email address.

This message is shown if the underlying data is not a valid email address.

checkMX¶

type: boolean default: false

If true, then the checkdnsrr PHP function will be used to check the validity of the MX record of the host of the given email.

checkHost¶

type: boolean default: false

If true, then the checkdnsrr PHP function will be used to check the validity of the MX or the A or the AAAA record of the host of the given email.

payload¶

type: mixed default: null

New in version 2.6: The payload option was introduced in Symfony 2.6.

This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to you.

For example, you may want to use several error levels to present failed constraints differently in the front-end depending on the severity of the error.
