Deprecation: #83608 - Backend user's getDefaultUploadFolder hook

See forge#83608


The hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauthgroup.php']['getDefaultUploadFolder'] has been marked as deprecated in favor of a new PSR-14 event AfterDefaultUploadFolderWasResolvedEvent.

Along with the hook, the two methods:

  • BackendUserAuthentication->getDefaultUploadFolder()
  • BackendUserAuthentication->getDefaultUploadTemporaryFolder()

have been marked as internal, as they are not considered part of the public TYPO3 API anymore.


Using this hook will trigger a PHP deprecation notice every time the method BackendUserAuthentication->getDefaultUploadFolder() is called,

Affected installations

TYPO3 installations with special functionality in extensions using these methods or the hook.


Migrate to the PSR-14 event AfterDefaultUploadFolderWasResolvedEvent in your custom extensions.

It is fired after various page TSconfig settings have been applied and allows for more fine-grained control.
