Max
Max¶
Validates that a given number is less than some maximum number.
| Applies to | property or method |
| Options | |
| Class | Max |
| Validator | MaxValidator |
Basic Usage¶
To verify that the "age" field of a class is not greater than "50", you might add the following:
- YAML
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. }
- Annotations
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; }
- XML
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>
- PHP
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.', ))); } }
Options¶
limit¶
type: integer [default option]
This required option is the "max" value. Validation will fail if the given value is greater than this max value.
message¶
type: string default: This value should be {{ limit }} or less
The message that will be shown if the underlying value is greater than the limit option.
invalidMessage¶
type: string default: This value should be a valid number
The message that will be shown if the underlying value is not a number (per
the is_numeric PHP function).
