Collection

This constraint is used when the underlying data is a collection (i.e. an array or an object that implements Traversable), but you’d like to validate every item of that collection against one or more constraints. For example, you might validate a collection of email addresses using the Email and NotBlank constraint.

In contradiction to the Collection constraint provided by Symfony, this constraint is used to validate every item in a collection against the same set of constraints.

Applies to:

• properties
• methods

Options:

• constraints

Basic Usage

Attributes

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

use DarkWebDesign\SymfonyAddonConstraints as AddonAssert;
use Symfony\Component\Validator\Constraints as Assert;

class Person
{
    #[AddonAssert\Collection(
        constraints: [
            new Assert\Email,
            new Assert\NotBlank
        ]
    )]
    protected $emails;
}

YAML

# src/AppBundle/Resources/config/validation.yml
AppBundle\Entity\Person:
    properties:
        emails:
            - DarkWebDesign\SymfonyAddonConstraints\Collection:
                constraints:
                    - Email
                    - NotBlank
