Basic Usage

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

    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

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

2.6The payload option was introduced in Symfony 2.6.

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.

For example, you may want to used several error levels to present failed constraint differently in the front-end depending on the severity of the error.
