| 22 | +Basic Usage |
| 23 | +----------- |
| 24 | + |
| 25 | +If you want to ensure that the ``age`` of a ``Person`` class is less than or |
| 26 | +equal to ``80``, you could do the following: |
| 27 | + |
| 28 | +..configuration-block:: |
| 29 | + |
| 30 | + ..code-block::yaml |
| 31 | +
|
| 32 | +# src/SocialBundle/Resources/config/validation.yml |
| 33 | +Acme\SocialBundle\Entity\Person: |
| 34 | +properties: |
| 35 | +age: |
| 36 | + -LessThanOrEqual: |
| 37 | +value:80 |
| 38 | +
|
| 39 | + ..code-block::php-annotations |
| 40 | +
|
| 41 | + // src/Acme/SocialBundle/Entity/Person.php |
| 42 | + namespace Acme\SocialBundle\Entity; |
| 43 | +
|
| 44 | + use Symfony\Component\Validator\Constraints as Assert; |
| 45 | +
|
| 46 | + class Person |
| 47 | + { |
| 48 | + /** |
| 49 | + * @Assert\LessThanOrEqual( |
| 50 | + * value = 80 |
| 51 | + * ) |
| 52 | + */ |
| 53 | + protected $age; |
| 54 | + } |
| 55 | +
|
| 56 | + ..code-block::xml |
| 57 | +
|
| 58 | +<!-- src/Acme/SocialBundle/Resources/config/validation.xml--> |
| 59 | + <classname="Acme\SocialBundle\Entity\Person"> |
| 60 | + <propertyname="age"> |
| 61 | + <constraintname="LessThanOrEqual"> |
| 62 | + <optionname="value">80</option> |
| 63 | + </constraint> |
| 64 | + </property> |
| 65 | + </class> |
| 66 | +
|
| 67 | + ..code-block::php |
| 68 | +
|
| 69 | + // src/Acme/SocialBundle/Entity/Person.php |
| 70 | + namespace Acme\SocialBundle\Entity; |
| 71 | +
|
| 72 | + use Symfony\Component\Validator\Mapping\ClassMetadata; |
| 73 | + use Symfony\Component\Validator\Constraints as Assert; |
| 74 | +
|
| 75 | + class Person |
| 76 | + { |
| 77 | + public static function loadValidatorMetadata(ClassMetadata $metadata) |
| 78 | + { |
| 79 | + $metadata->addPropertyConstraint('age', new Assert\LessThanOrEqual(array( |
| 80 | + 'value' => 80, |
| 81 | + ))); |
| 82 | + } |
| 83 | + } |
| 84 | +
