# Deprecation: #98479 - Deprecated file reference related functionality {#deprecation-98479-1664622350}

See [forge#98479](https://forge.typo3.org/issues/98479)

## Description {#description}

With the introduction of the new TCA type `file`, a couple of cross
dependencies have been deprecated, mainly related to FormEngine.

The `UserFileInlineLabelService` class has been deprecated, since it was
only used for generating the inline label for file references in TCA type
`inline`. This is now handled by the new TCA type `file` directly.

The `FileExtensionFilter->filterInlineChildren()` method, which was
previously used as `[filter][userFunc]` to filter the available
file extensions in FormEngine as well as `DataHandler` has been
deprecated. This is now done internally.

The `ExtensionManagementUtility::getFileFieldTCAConfig()` method, which
was usually used to simplify configuration of FAL fields in TCA has been
deprecated as well, since the applied configuration is now handled internally.

## Impact {#impact}

Instantiating the `UserFileInlineLabelService` class, as well as
calling the `FileExtensionFilter->filterInlineChildren()` and
`ExtensionManagementUtility::getFileFieldTCAConfig()` methods will
trigger a PHP `E_USER_DEPRECATED` level error. The extension scanner
also reports any usage.

## Affected installations {#affected-installations}

All installations with extensions using the `UserFileInlineLabelService`
class or one of the mentioned methods.

## Migration {#migration}

Remove any usage of the `UserFileInlineLabelService` class. There is no
migration available, since this FAL specific functionality is now handled
internally.

Replace any usage of `FileExtensionFilter->filterInlineChildren()` with
`FileExtensionFilter->filter()`. However, usage of this method in custom
extension code should usually not be necessary.

Replace any usage of `ExtensionManagementUtility::getFileFieldTCAConfig()`
by directly using the new TCA type [file](https://docs.typo3.org/permalink/changelog:feature-98479-1664537749).
