Symfony 3.1 - create global parameter for AppBundle - php

Question

I'm trying to define some parameters inside the AppBundle without success. It's one of my first test on this framework so there may be obvious concept that I misunderstood.
The first problem is the field bundle_version which is not read inside the YAML file. The error returned is the following :
[Symfony\Component\Config\Definition\Exception\InvalidConfigurationException]
The child node "bundle_version" at path "costs" must be configured.
When i comment this line, i get another error :
[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException]
There is no extension able to load the configuration for "costs" (in W:\wamp64\www\test\src\AppBundle\DependencyInjecti
on/../Resources/config\costs.yml). Looked for namespace "costs", found none
src/AppBundle/DependencyInjection/Configuration.php
namespace AppBundle\DependencyInjection;
use Symfony\Component\Config\Definition\ConfigurationInterface;
use Symfony\Component\Config\Definition\Builder\TreeBuilder;
class Configuration implements ConfigurationInterface
{
public function getConfigTreeBuilder()
{
$treeBuilder = new TreeBuilder();
$rootNode = $treeBuilder->root('costs');
$rootNode->children()
// THIS LINE DON'T WORK AND CAUSE THE 1st PROBLEM
->floatNode('bundle_version')->isRequired()->end()
->arrayNode('shipping')
->children()
->floatNode('es')->isRequired()->end()
->floatNode('it')->isRequired()->end()
->floatNode('uk')->isRequired()->end()
->end()
->end()
->arrayNode('services')
->children()
->floatNode('serviceA')->isRequired()->end()
->floatNode('serviceB')->isRequired()->end()
->end()
->end()
->end();
return $treeBuilder;
}
}
/src/AppBundle/Resources/config.costs.yml
costs:
bundle_version: 1.0 # THIS FIELD IS NOT RECOGNIZED
shipping:
es: 18.00
it: 19.00
uk: 20.00
services:
serviceA: 15.00
serviceB: 20.00
/src/AppBundle/DependencyInjection/AppExtension.php
namespace AppBundle\DependencyInjection;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\DependencyInjection\Extension;
use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;
use Symfony\Component\Config\FileLocator;
class AppExtension extends Extension
{
public function load(array $config, ContainerBuilder $container)
{
$loader = new YamlFileLoader(
$container,
new FileLocator(__DIR__.'/../Resources/config')
);
$loader->load('costs.yml');
}
}

The solution is quite simple as i expected ... In /app/config/config.yml there's a predefined "parameters" key and we're supposed to putt our params here if they're not Bundle specific.
So it's just something like :
# /app/config/config.yml
imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: services.yml }
# Put parameters here that don't need to change on each machine where the app is deployed
# http://symfony.com/doc/current/best_practices/configuration.html#application- related-configuration
parameters:
locale: fr
my_param: my_value
Then in your controller :
// /src/AppBundle/Controller/DefaultController.php
class DefaultController extends Controller
{
/**
* #Route("/", name="homepage")
*/
public function indexAction(Request $request)
{
$this->getParameter('my_param'); // or $this->getContainer()->getParameter('my_param');
// replace this example code with whatever you need
return $this->render('default/index.html.twig', [
'base_dir' => realpath($this->getParameter('kernel.root_dir').'/..').DIRECTORY_SEPARATOR,
]);
}
}
Hope it helps
