Breaking: #92238 - Service injection in Extbase validators¶
See forge#92238
Description¶
With the deprecation and removal of objectManager usage in TYPO3, Extbase does not use the objectManager to create validator instances any more.
Note
This has been mitigated with recent TYPO3 v11 core releases: Extbase validators
can use dependency injection again. See this changelog
for details.
Additionally, all validators delivered by EXT:extbase and EXT:form will be marked
final
in v12. Extensions can no longer extend validators but must extend abstract
classes or implement the interfaces directly.
Impact¶
Validators that use dependency injection will experience non injected services for affected properties.
Affected Installations¶
All installations that use dependency injection in Extbase validators.
Migration¶
Instead of injecting services to the validator, use GeneralUtility::makeInstance
to create an instance of required services.
Given the following example for a service injection in a validator:
/**
* @var ConfigurationManagerInterface
*/
protected $configurationManager;
/**
* @param ConfigurationManagerInterface $configurationManager
*/
public function injectConfigurationManager(ConfigurationManagerInterface $configurationManager)
{
$this->configurationManager = $configurationManager;
}
Since the configurationManager is required globally in the class, GeneralUtility::makeInstance
is used in the constructor of the validator to create an instance of the service.
/**
* @var ConfigurationManagerInterface
*/
protected $configurationManager;
public function __construct(array $options = [])
{
$this->configurationManager = GeneralUtility::makeInstance(ConfigurationManagerInterface::class);
parent::__construct($options);
}
In order to create instances of services that require dependency injection and which
are not already instantiated in the service container, it is required to declare those
services as public: true
in the Configuration/Services.yaml
of the given extension.
