Adding a new CustomField type

RT Developers
1

Hi all,

I was originally wanting to add new CustomField types to enable things
like showing a flag for “Country” in addition to the text. But I just
realized I think I can do w/o a new type by using the
ShowComponentName Callback in Elements/ShowCustomFields. Has anyone
tried to do this? I can see the callback provides a Name (reference to
a string), the CustomField object and an Object (which I think will be
a Ticket object). I imagine I need to massage what
$Object->CustomFieldValues($CF_id) returns, but I’m not exactly sure
how to go about it. Alternately, I could create a new
Elements/ShowCustomField$type component and massage the Name to be the
new component.

Has anyone done this sort of thing and/or can provide an example?

Thanks,
Drew

While it’s possible to do that without a new field type, it’s a lot
cleaner if you create one anyway. For something like that you only
really need to register the field, and then create a Show and Edit
component for it. Doing it that way also keeps everything self
contained.
