Simplicity is at the heart of Silex so there is no out of the box solution to use YAML files for validation. But this doesn't mean that this is not possible. Let's see how to do it.
First, you need to install the YAML Component:
1 | composer require symfony/yaml
|
Next, you need to tell the Validation Service that you are not using
StaticMethodLoader
to load your class metadata but a YAML file:
1 2 3 4 5 | $app->register(new ValidatorServiceProvider());
$app['validator.mapping.class_metadata_factory'] = new Symfony\Component\Validator\Mapping\ClassMetadataFactory(
new Symfony\Component\Validator\Mapping\Loader\YamlFileLoader(__DIR__.'/validation.yml')
);
|
Now, we can replace the usage of the static method and move all the validation
rules to validation.yml
:
1 2 3 4 5 6 7 8 | # validation.yml
