ohh, not absolutely solved, sorry.
With the code above I get the list of all sub custom field values “artistname”, but not 100% correct. They are still sorted by posts (query-type “events”) somehow.
If events have only one row it works fine
exmpl:
Event 1 – artist – Abba
Event 2 – artist – Duran Duran
Event 3 – artist – Foo Fighters
But if an events has more then one row, not the row itselves is posted alphabeticaly.
exmpl:
Event 4 – artist – Coldplay, Aerosmith, Eminem
The list looks like this:
- Abba (event 1)
- Coldplay (event 4.1)
- Aerosmith (event 4.2)
- Eminem (event 4.3)
- Duran Duran (event 2)
- Foo Fighters (event 3)
It should look lite that, 100% alphabeticaly:
- Abba (event 1)
- Aerosmith (event 4.2)
- Coldplay (event 4.1)
- Duran Duran (event 2)
- Eminem (event 4.3)
- Foo Fighters (event 3)
