# OnGetCustomFields

The **OnGetCustomFields** event can be implemented by a [rename script](https://chaoses-ib.gitbook.io/directory-opus/manual/scripting/rename_scripts) to add [custom fields](https://chaoses-ib.gitbook.io/directory-opus/manual/scripting/rename_scripts/custom_fields_in_the_rename_dialog) to the *Rename* dialog. This lets you provide one or more controls that users can use to pass parameters to your script.
