PSR-14 Events

FAL comes with a series of PSR-14 events that offer the opportunity to hook into FAL processes at a variety of points.

They are listed below with some explanation, in particular when they are sent (if the name is not explicit enough) and what parameters the corresponding event will receive. They are grouped by emitting class.

Most events exist in pairs, one being sent before a given operation, the other one after.

Note

Unless mentioned otherwise, mentions of class “File” below actually refer to the \TYPO3\CMS\Core\Resource\FileInterface interface.

“Folder” objects actually refer to the \TYPO3\CMS\Core\Resource\Folder class.

AfterFileAddedEvent
Receives the File instance corresponding to the newly stored file and the target folder (as a Folder instance).
AfterFileCreatedEvent
Receives the identifier of the newly created file and the target folder (as a Folder instance).
BeforeFileCopiedEvent
Receives a File instance for the file to be copied and the target folder (as a Folder instance).
AfterFileCopiedEvent
Receives a File instance for the file that was copied (i.e. the original file) and the target folder (as a Folder instance).
BeforeFileMovedEvent
Receives a File instance for the file to be moved and the target folder (as a Folder instance).
AfterFileMovedEvent
Receives a File instance for the file that was moved, the target folder and the original folder the file was in (both as Folder instances).

AfterFolderCopiedEvent
Receives references to the original folder and the parent target folder (both as \TYPO3\CMS\Core\Resource\FolderInterface instances) and the identifier of the newly copied folder.
BeforeFolderMovedEvent

AfterFolderMovedEvent
Receives references to the folder to move and the parent target folder (both as Folder instances), the identifier of the moved folder and a reference to the original parent folder (as a Folder instance).
BeforeFolderDeletedEvent
Receives a reference to the folder to delete (as a Folder instance).
AfterFolderDeletedEvent
Receives a reference to the deleted folder (as a Folder instance).
BeforeFolderRenamedEvent
Receives a reference to the folder to be renamed (as a Folder instance) and the sanitized new name.
AfterFolderRenamedEvent
Receives a reference to the renamed folder (as a Folder instance) and the new identifier of the renamed folder.
GeneratePublicUrlForResourceEvent

This event makes it possible to influence the construction of a resource’s public URL. If the event defines the URL, it is kept as is and the rest of the URL generation process is ignored.

It receives a reference to the instance for which the URL should be generated (as a \TYPO3\CMS\Core\Resource\ResourceInterface instance), a boolean flag indicating whether the URL should be relative to the current script or absolute and a reference to the public URL (which is null at this point, but can be then modified by the event).

\TYPO3\CMS\Core\Resource\ResourceFactory

BeforeResourceStorageInitializationEvent
This event is dispatched by method \TYPO3\CMS\Core\Resource\ResourceFactory::getStorageObject() before a Storage object has been fetched. The event receives a reference to the Storage.
AfterResourceStorageInitializationEvent
This event is dispatched by method \TYPO3\CMS\Core\Resource\ResourceFactory::getStorageObject() after a Storage object has been fetched. The event receives a reference to the Storage.

\TYPO3\CMS\Core\Resource\Index\FileIndexRepository

AfterFileAddedToIndexEvent
Receives an array containing the information collected about the file whose index (i.e. “sys_file” table entry) was just created.
AfterFileUpdatedInIndexEvent
Receives an array containing the information collected about the file whose index (i.e. “sys_file” table entry) was just updated.
AfterFileRemovedFromIndexEvent
Receives the uid of the file (i.e. “sys_file” table entry) which was deleted.
AfterFileMarkedAsMissingEvent
Receives the uid of the file (i.e. “sys_file” table entry) which was marked as missing.

\TYPO3\CMS\Core\Resource\Index\MetaDataRepository

EnrichFileMetaDataEvent
This event is dispatched after metadata has been retrieved for a given file. The event receives the metadata as an \ArrayObject instance.
AfterFileMetaDataCreatedEvent
Receives an array containing the metadata collected about the file just after it has been inserted into the “sys_file_metadata” table.
AfterFileMetaDataUpdatedEvent
This event is dispatched after metadata for a given file has been updated. The event receives the metadata as an array containing all metadata fields (and not just the updated ones).
AfterFileMetaDataDeletedEvent
Receives the uid of the file whose metadata has just been deleted.

\TYPO3\CMS\Core\Resource\Service\FileProcessingService

BeforeFileProcessingEvent
This event is dispatched before a file is processed. The event receives a reference to the processed file and to the original file (both as File instances), a string defining the type of task being executed and an array containing the configuration for that task.
AfterFileProcessingEvent
This event is dispatched after a file has been processed. The event receives a reference to the processed file and to the original file (both as File instances), a string defining the type of task being executed and an array containing the configuration for that task.
