2.3 新版功能: The Isbn constraint was introduced in Symfony 2.3.
警告
The isbn10 and isbn13 options are deprecated since Symfony 2.5
and will be removed in Symfony 3.0. Use the type option instead.
Furthermore, when using the type option, lowercase characters are no
longer supported starting in Symfony 2.5, as they are not allowed in ISBNs.
This constraint validates that an International Standard Book Number (ISBN) is either a valid ISBN-10 or a valid ISBN-13.
| Applies to | property or method |
| Options | |
| Class | Isbn |
| Validator | IsbnValidator |
To use the Isbn validator, simply apply it to a property or method
on an object that will contain an ISBN.

type: string default: null
The type of ISBN to validate against.
Valid values are isbn10, isbn13 and null to accept any kind of ISBN.
type: string default: null
The message that will be shown if the value is not valid.
If not null, this message has priority over all the other messages.
type: string default: This value is not a valid ISBN-10.
The message that will be shown if the type option is isbn10 and the given
value does not pass the ISBN-10 check.
type: string default: This value is not a valid ISBN-13.
The message that will be shown if the type option is isbn13 and the given
value does not pass the ISBN-13 check.
type: string default: This value is neither a valid ISBN-10 nor a valid ISBN-13.
The message that will be shown if the type option is null and the given
value does not pass any of the ISBN checks.
type: mixed default: null
2.6 新版功能: 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.
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.
