// src/AppBundle/Entity/User.php
namespace AppBundle\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class User
{
/**
* @Assert\Language
*/
protected $preferredLanguage;
}Note
As with most of the other constraints, null and empty strings are
considered valid values. This is to allow them to be optional values.
If the value is mandatory, a common solution is to combine this constraint
with NotBlank.
Options
message
type: string default: This value is not a valid language.
This message is shown if the string is not a valid language code.
You can use the following parameters in this message:
| Parameter | Description |
|---|---|
{{ value }} |
The current (invalid) value |
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.
