When applied to an array (or Traversable object), this constraint allows you to apply a collection of constraints to each element of the array.
Suppose that you have an array of strings and you want to validate each entry in that array:
.. configuration-block:: .. code-block:: php-attributes // src/Entity/User.php namespace App\Entity; use Symfony\Component\Validator\Constraints as Assert; class User { #[Assert\All([ new Assert\NotBlank, new Assert\Length(min: 5), ])] protected array $favoriteColors = []; } .. code-block:: yaml # config/validator/validation.yaml App\Entity\User: properties: favoriteColors: - All: - NotBlank: ~ - Length: min: 5 .. code-block:: xml <!-- config/validator/validation.xml --> <?xml version="1.0" encoding="UTF-8" ?> <constraint-mapping xmlns="http://symfony.com/schema/dic/constraint-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://symfony.com/schema/dic/constraint-mapping https://symfony.com/schema/dic/constraint-mapping/constraint-mapping-1.0.xsd"> <class name="App\Entity\User"> <property name="favoriteColors"> <constraint name="All"> <option name="constraints"> <constraint name="NotBlank"/> <constraint name="Length"> <option name="min">5</option> </constraint> </option> </constraint> </property> </class> </constraint-mapping> .. code-block:: php // 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): void { $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.
type: array
[:ref:`default option <validation-default-option>`]
This required option is the array of validation constraints that you want to apply to each element of the underlying array.
