ModifyBlindedConfigurationOptionsEvent

New in version 12.2: The event serves as a direct replacement for the deprecated hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['TYPO3\CMS\Lowlevel\Controller\ConfigurationController']['modifyBlindedConfigurationOptions'].

The PSR-14 event \TYPO3\CMS\Lowlevel\Event\ModifyBlindedConfigurationOptionsEvent is fired in the \TYPO3\CMS\Lowlevel\ConfigurationModuleProvider\GlobalVariableProvider and the \TYPO3\CMS\Lowlevel\ConfigurationModuleProvider\SitesYamlConfigurationProvider while building the configuration array to be displayed in the System > Configuration module. It allows to blind (hide) any configuration options. Usually such options are passwords or other sensitive information.

Using the getProviderIdentifier() method of the event, listeners are able to determine the context the event got dispatched in. This is useful to prevent duplicate code execution, since the event is dispatched for multiple providers. The method returns the identifier of the configuration provider as registered in the configuration module.

Example

Registration of the ModifyBlindedConfigurationOptionsEvent in your extension's Services.yaml:

EXT:my_extension/Configuration/Services.yaml

MyVendor\MyExtension\Backend\MyEventListener:
  tags:
    - name: event.listener
      identifier: 'my-extension/blind-configuration-options'

The corresponding event listener:

EXT:my_extension/Classes/Backend/MyEventListener.php

namespace MyVendor\MyExtension\Backend;

use TYPO3\CMS\Lowlevel\ConfigurationModuleProvider\GlobalVariableProvider;
use TYPO3\CMS\Lowlevel\ConfigurationModuleProvider\SitesYamlConfigurationProvider;
use TYPO3\CMS\Lowlevel\Event\ModifyBlindedConfigurationOptionsEvent;

final class MyEventListener {

    public function __invoke(ModifyBlindedConfigurationOptionsEvent $event): void
    {
        $options = $event->getBlindedConfigurationOptions();

        if ($event->getProviderIdentifier() === 'sitesYamlConfiguration') {
            $options['my-site']['settings']['apiKey'] = '***';
        } elseif ($event->getProviderIdentifier() === 'confVars') {
            $options['TYPO3_CONF_VARS']['EXTENSIONS']['my_extension']['password'] = '***';
        }

        $event->setBlindedConfigurationOptions($options);
    }
}
