Use parameters in Symfonybundle in service class - php

Question

I have Symfony bundle called upload images:
I want to use parameters in my bundle in my class.
This is my parameter file:
upload-images:
image:
crop_size: 300
My files:
Configuration.php
class Configuration implements ConfigurationInterface
{
public function getConfigTreeBuilder()
{
$treeBuilder = new TreeBuilder('upload-images');
$treeBuilder->getRootNode()
->children()
->arrayNode('image')
->children()
->integerNode('save_original')->end()
->scalarNode('crop_size')->end()
->end()
->end() // twitter
->end();
return $treeBuilder;
}
}
UploadImagesExtension.php
class UploadImagesExtension extends Extension
{
public function load(array $configs, ContainerBuilder $container)
{
$loader = new YamlFileLoader($container, new FileLocator(dirname(__DIR__).'/Resources'));
$loader->load('services.yaml');
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
}
}
And final my service class:
Rotate.php
And in this class I want the parameter: crop_size
I tried the ParameterBagInterface:
use Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface;
class Rotate
{
private $params;
public function __construct(ParameterBagInterface $params)
{
$this->params = $params;
}
public function Rotate()
{
$cropSize = $params->get('crop_size');
}
}
UserController.php
use verzeilberg\UploadImagesBundle\Service\Rotate;
class UserController extends AbstractController
{
/** #var UserProfileService */
private $service;
private $userService;
public function __construct(
UserProfileService $service,
UserService $userService
) {
$this->service = $service;
$this->userService = $userService;
}
/**
* #param UserInterface $user
* #return Response
*/
public function profile(UserInterface $user)
{
$rotate = new Rotate();
$rotate->Rotate();
.....
...
}
Getting this error:
Too few arguments to function verzeilberg\UploadImagesBundle\Service\Rotate::__construct(), 0 passed in /home/vagrant/projects/diabetigraph-dev/src/Controller/User/UserController.php on line 62 and exactly 1 expected
I have search for a solution. But did not came accross the right one.

Answer 1

According to the latest edit, the error is pretty obvious: if you want to use dependency injection, you have to use it. Calling $rotate = new Rotate(); without any constructor parameters will fail, as Symfony cannot inject them for you.
Instead, inject it through the action:
public function profile(UserInterface $user, Rotate $rotate)
... this will use Symfony's container and inject the ParameterBagInterface, if you have enabled autowiring. If not, you have to write the proper service definitions to get this done

Answer 2

The error you are getting is not directly related to your question.
Either it is an autowiring issue, or maybe you are trying to instanciate the service manually? Please share what you are doing here: UserController.php on line 62
Anyway, to answer your question:
To access the parameters from the parameter bag you will have to set them in the extension.
$container->setParameter('my_bundle.config', $config);
Also, injecting the whole ParameterBag is fine for a project, but should be avoided for a bundle.
Use the DI config to inject just your parameter, OR make your extension implement CompilerPassInterface, and override the definition there. (It may be overkill for such a simple task)
