Need help with Functions

Hello musicbee community,

using a virtual tag, I'd like to display Album [Mediatype Albumtype Releasetype], but not all tag fields have a value.

With this code

Code

<Album> [$Trim($IsNull(<Mediatype>,,<Mediatype>" ")$IsNull(<Albumtype>,,<Albumtype>" ")$IsNull(<Releasetype>,,<Releasetype>" "))]

a space and the square brackets are still visible, when Mediatype, Albumtype and Releasetype are empty. I couldn't find a way to hide them in that case.

Has anyone an idea how to only display only Album, when the three tag fields are empty?

I haven't tested it, but from just looking at it this might work...

Code

<Album> $IsNull(<Mediatype><Albumtype><Releasetype>,,[$Trim($IsNull(<Mediatype>,,<Mediatype>" ")$IsNull(<Albumtype>,,<Albumtype>" ")$IsNull(<Releasetype>,,<Releasetype>" "))])

If not you could use $And's

Thanks a lot Pickles7853,

that worked, but left a space after Album if the three tag fields had no value. I tweaked your code to

Code

<Album>$IsNull(<Mediatype><Albumtype><Releasetype>,," ["$Trim($IsNull(<Mediatype>,,<Mediatype>" ")$IsNull(<Albumtype>,,<Albumtype>" ")$IsNull(<Releasetype>,,<Releasetype>" "))])

and now everything is great.  

P.S.: I think, that group intelligence is superior to AI, which failed to provide a solution here.
