Sometimes the new ServiceManager(s) in Zend Framework 2 are a bit confusing. We don’t have one, we have several instances.
So recently I was writing a factory for a ViewHelper and wanted to access the application configuration from there. As usual, I was attempting it like this
[code lang=”php”]
/**
* @param ServiceLocatorInterface $serviceLocator
* @return MyConfiguration
*/
public function createService(ServiceLocatorInterface $serviceLocator)
{
$instance = new MyConfiguration();
$configuration = $serviceLocator->get(‘configuration’);
// haha – nope!
if(!empty($configuration[‘whatever’])) {
$instance->setConfiguration($configuration[‘whatever’]);
}
return $instance;
}[/code]
It ended up throwing an exception, saying the configuration could not be found. To make it short, after some searching I found this one
[code lang=”php”]$serviceManager = $serviceLocator->getServiceLocator();[/code]
Intuitive, isn’t it? But it seems to work, so the factory looks like this now:
[code lang=”php”]
/**
* @param ServiceLocatorInterface $serviceLocator
* @return MyConfiguration
*/
public function createService(ServiceLocatorInterface $serviceLocator)
{
$serviceManager = $serviceLocator->getServiceLocator();
$instance = new MyConfiguration();
$configuration = $serviceManager->get(‘configuration’);
if(!empty($configuration[‘whatever’])) {
$instance->setConfiguration($configuration[‘whatever’]);
}
return $instance;
}[/code]
