# Breaking: #81763 - Hook parameters of \['typo3/file_edit.php'\]\['preOutputProcessingHook'\] changed {#breaking-81763}

See [forge#81763](https://forge.typo3.org/issues/81763)

## Description {#description}

The hook parameters passed into `$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/file_edit.php']['preOutputProcessingHook']`
have been changed due to rewriting the edit file form to use FormEngine.

## Impact {#impact}

Any information added to modify the output may have no effect anymore.

## Affected Installations {#affected-installations}

Every installation using an extension that hooks into `$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['typo3/file_edit.php']['preOutputProcessingHook']`
to modify the form's output is affected.

## Migration {#migration}

As the form is based on FormEngine now, you may want to adjust the newly introduced hook parameter `$dataColumnDefinition`,
representing the definition of the `data` field which contains the file content. An example can be found in EXT:t3editor.
