Basic Usage
To verify that the "age" field of a class is not greater than "50", you might add the following:
1 2 3 4 5
# src/Acme/EventBundle/Resources/config/validation.yml
Acme\EventBundle\Entity\Participant:
properties:
age:
- Max: { limit: 50, message: You must be 50 or under to enter. }
1 2 3 4 5 6 7 8 9 10 11 12
// src/Acme/EventBundle/Entity/Participant.php
namespace Acme\EventBundle\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class Participant
{
/**
* @Assert\Max(limit = 50, message = "You must be 50 or under to enter.")
*/
protected $age;
}
1 2 3 4 5 6 7 8 9
<!-- src/Acme/EventBundle/Resources/config/validation.yml -->
<class name="Acme\EventBundle\Entity\Participant">
<property name="age">
<constraint name="Max">
<option name="limit">50</option>
<option name="message">You must be 50 or under to enter.</option>
</constraint>
</property>
</class>
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
// src/Acme/EventBundle/Entity/Participant.php
namespace Acme\EventBundle\Entity;
use Symfony\Component\Validator\Mapping\ClassMetadata;
use Symfony\Component\Validator\Constraints as Assert;
class Participant
{
public static function loadValidatorMetadata(ClassMetadata $metadata)
{
$metadata->addPropertyConstraint('age', new Assert\Max(array(
'limit' => 50,
'message' => 'You must be 50 or under to enter.',
)));
}
}
