All

When applied to an array (or Traversable object), this constraint allows you to apply a collection of constraints to each element of the array.

Applies to property or method
Options
Class Symfony\Component\Validator\Constraints\All
Validator Symfony\Component\Validator\Constraints\AllValidator

Basic Usage

Suppose that you have an array of strings and you want to validate each entry in that array:

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

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

class User
{
    public static function loadValidatorMetadata(ClassMetadata $metadata)
    {
        $metadata->addPropertyConstraint('favoriteColors', new Assert\All(array(
            'constraints' => array(
                new Assert\NotBlank(),
                new Assert\Length(array('min' => 5)),
            ),
        )));
    }
}

Now, each entry in the favoriteColors array will be validated to not be blank and to be at least 5 characters long.

Options

constraints

type: array [default option]

This required option is the array of validation constraints that you want to apply to each element of the underlying array.

payload

type: mixed default: null

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.
