New in version 13.0
The PHP attribute \TYPO3\
has been
introduced to tag a PHP class as an event listener. Alternatively, or if you
need to be compatible with older TYPO3 versions, you can also register an
event listener via the Configuration/
file. Switch to
an older version of this page for an example or have a look at the section
Implementing an event listener in your extension.
