payload

type: mixed default: null

New in version 2.6

The 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 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.
