Basic Usage¶
If you want to ensure that the currency
property of an Order
is
a valid currency, you could do the following:
- Annotations
1 2 3 4 5 6 7 8 9 10 11 12
// src/AppBundle/Entity/Order.php namespace AppBundle\Entity; use Symfony\Component\Validator\Constraints as Assert; class Order { /** * @Assert\Currency */ protected $currency; }
- YAML
1 2 3 4 5
# src/AppBundle/Resources/config/validation.yml AppBundle\Entity\Order: properties: currency: - Currency: ~
- XML
1 2 3 4 5 6 7 8 9 10 11 12
<!-- src/AppBundle/Resources/config/validation.xml --> <?xml version="1.0" encoding="UTF-8" ?> <constraint-mapping xmlns="http://symfony.com/schema/dic/constraint-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://symfony.com/schema/dic/constraint-mapping http://symfony.com/schema/dic/constraint-mapping/constraint-mapping-1.0.xsd"> <class name="AppBundle\Entity\Order"> <property name="currency"> <constraint name="Currency" /> </property> </class> </constraint-mapping>
- PHP
1 2 3 4 5 6 7 8 9 10 11 12 13
// src/AppBundle/Entity/Order.php namespace AppBundle\Entity; use Symfony\Component\Validator\Mapping\ClassMetadata; use Symfony\Component\Validator\Constraints as Assert; class Order { public static function loadValidatorMetadata(ClassMetadata $metadata) { $metadata->addPropertyConstraint('currency', new Assert\Currency()); } }
Options¶
message¶
type: string
default: This value is not a valid currency.
This is the message that will be shown if the value is not a valid currency.
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.
