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 All
Validator AllValidator

Basic Usage

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

  • YAML

    # src/UserBundle/Resources/config/validation.yml
Acme\UserBundle\Entity\User:
    properties:
        favoriteColors:
            - All:
                - NotBlank:  ~
                - Length:
                    min: 5

use Symfony\Component\Validator\Constraints as Assert;

class User
{
    /**
     * @Assert\All({
     *     @Assert\NotBlank
     *     @Assert\Length(min = "5"),
     * })
     */
     protected $favoriteColors = array();
}

                <constraint name="Length">
                    <option name="min">5</option>
                </constraint>
            </option>
        </constraint>
    </property>
</class>

    // src/Acme/UserBundle/Entity/User.php
namespace Acme\UserBundle\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

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.
