This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.

Extending T3extlog

Using interfaces

Some internal services are implemented as interfaces. The actual class to use could be configured by TypoScript. This way it is possible to use custom implementations.

See config.tx_extbase.objects configuration in [ext_typoscript_setup.txt](../../ext_typoscript_setup.txt).

Signal / Slot

T3extblog provides a couple of hooks to extend or change the default behavior. This is done by using the signal / slot functionality provided by TYPO3.

Available signals

  • sendEmail in FelixNagelT3extblogServiceEmailService
  • subscriberConfirmAction in FelixNagelT3extblogControllerCommentSubscriberController
  • subscriberDeleteAction in FelixNagelT3extblogControllerCommentSubscriberController
  • subscriberConfirmAction in FelixNagelT3extblogControllerPostSubscriberController
  • subscriberDeleteAction in FelixNagelT3extblogControllerPostSubscriberController
  • processNewComment in FelixNagelT3extblogServiceCommentNotificationService
  • processChangedComment in FelixNagelT3extblogServiceCommentNotificationService
  • notifySubscribers in FelixNagelT3extblogServiceCommentNotificationService
  • processNewSubscriber in FelixNagelT3extblogServiceBlogNotificationService
  • processChangedSubscriber in FelixNagelT3extblogServiceBlogNotificationService
  • notifySubscribers in FelixNagelT3extblogServiceBlogNotificationService
  • spamCheck in FelixNagelT3extblogServiceSpamCheckService
  • prePersist in FelixNagelT3extblogControllerCommentController

Example code

for using the EmailService sendEmail signal:

// typo3conf/ext/my_extension/ext_localconf.php
$signalSlotDispatcher = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(

Table mapping

This extension uses TYPO3 Extbase table mapping to make use of existing EXT:t3blog tables. Take a look at ext_typoscript_setup.txt to see how this is done.


Translations could be added here:

Please consider opening a GitHub ticket so we can review new translations as soon as possible!


German localization has been handled by local files before version 2.2.0. Please see this issue for more information:

How to release

  • Change version information in /ext_emconf.php
  • Change version information in /Documentation/Settings.yml and /Documentation/Settings.cfg
  • Commit changes: No [XYZ] prefix, this commit message will be the TYPO3 TER release notice
  • Add tag to release commit (format: “1.2.3”)
  • Change version information in /ext_emconf.php to next bugfix version + “dev” (example: “1.2.4dev”)
