All

Warning: You are browsing the documentation for Symfony 4.x, which is no longer maintained.

Read the updated version of this page for Symfony 7.1 (the current stable version).

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
Class	All
Validator	AllValidator

Basic Usage

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

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

use Symfony\Component\Validator\Constraints as Assert;

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

App\Entity\User:
    properties:
        favoriteColors:
            - All:
                - NotBlank:  ~
                - Length:
                    min: 5

                </option>
            </constraint>
        </property>
    </class>
</constraint-mapping>

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

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

class User
{
    public static function loadValidatorMetadata(ClassMetadata $metadata)
    {
        $metadata->addPropertyConstraint('favoriteColors', new Assert\All([
            'constraints' => [
                new Assert\NotBlank(),
                new Assert\Length(['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.

`groups`

type: array | string

It defines the validation group or groups of this constraint. Read more about validation groups.

`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.
