my goal was to make a bundle with a configurable doctrine listener to allow the user to configure the connection and the priority for a postLoad event.
i had the following listener code service.yaml:
C33s\Doctrine\Listener\InjectFeatureManagerListener:
tags:
- { name: doctrine.event_listener, event: postLoad, connection: default, priority: 0 }
and i changed it to:
C33s\Doctrine\Listener\InjectFeatureManagerListener:
tags:
- { name: doctrine.event_listener, event: postLoad, connection: '%c33s_doctrine_extra.flagception.connection%', priority: '%c33s_doctrine_extra.flagception.priority%' }
Configuration.php
<?php
class Configuration implements ConfigurationInterface
{
/**
* {@inheritdoc}
*/
public function getConfigTreeBuilder()
{
$treeBuilder = new TreeBuilder('c33s_doctrine_extra');
$treeBuilder->getRootNode()
->addDefaultsIfNotSet()
->children()
->arrayNode('flagception')
->canBeEnabled()
->children()
->scalarNode('connection')
->defaultValue('default')
->end()
->integerNode('priority')
->defaultValue(0)
->info('to the same event (default priority = 0; higher numbers = listener is run earlier)')
->end()
->end()
->end()
->end()
;
return $treeBuilder;
}
}
C33sDoctrineExtraExtension.php
<?php
class C33sDoctrineExtraExtension extends Extension
{
/**
* {@inheritdoc}
*/
public function load(array $configs, ContainerBuilder $container)
{
$configuration = new Configuration();
$config = $this->processConfiguration($configuration, $configs);
$loader = new Loader\YamlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
if (true === $config['flagception']['enabled']) {
$container->setParameter('c33s_doctrine_extra.flagception.connection', $config['flagception']['connection']);
$container->setParameter('c33s_doctrine_extra.flagception.priority', $config['flagception']['priority']);
$loader->load('entity_feature_manager_injector.yaml');
}
// $loader->load('services.yaml');
}
}
which failed with:
Fatal error: Uncaught Symfony\Component\Debug\Exception\FatalThrowableError: Cannot unpack array with string keys in ...\vendor\symfony\doctrine-bridge\DependencyInjection\CompilerPass\RegisterEventListenersAndSubscribersPass.php on line 144

digging into RegisterEventListenersAndSubscribersPass showed me that the parameters aren't resolved yet.
this is because the doctrines compiler pass RegisterEventListenersAndSubscribersPass which is instantiated in DoctrineBundle is instantiated with PassConfig::TYPE_BEFORE_OPTIMIZATION pass and in Symfony\Component\DependencyInjection\Compiler\PassConfig we can see, that the ResolveParameterPlaceHoldersPass is a PassConfig::TYPE_OPTIMIZE pass. which is executed after RegisterEventListenersAndSubscribersPass.
so no easy configureable doctrine listeners -.-
