I want to add a "edit custom record" button to the doc header of the typo3 backend when the "Web > Page" module is active.
This is possible by registering a listener to the modify-button-bar event and works fine.
In my event listener class, I obtain the ID of the currently selected page with
$pageUid = (int)\TYPO3\CMS\Core\Utility\GeneralUtility::_GP('id');
The problem now is that the button is also shown when the Web > View, Web > List, Web > Info modules are active.
Unfortunately, there are no other GET parameters than id
and token
.
How can I find out if the "Web > Page" module is active?
There is no official way to obtain the request object in event listeners in v12, so I have to resort to the global object:
$GLOBALS['TYPO3_REQUEST']->getAttribute('route')->getOption('_identifier');
It will return web_layout
.
