Options

format

type: string default: Y-m-d H:i:s

This option allows to validate a custom date format. See DateTime::createFromFormat() for formatting options.

message

type: string default: This value is not a valid datetime.

This message is shown if the underlying data is not a valid datetime.

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.
