Hm, thats a real pitty, more sophisticated queries than “get all categories” or “get only a single category” should definitley make it into the core. the whole custom taxonomy construct loses a lot of value if you cant perform more advanced queries on these entries :/
I am building a gallery theme that uses a custom term for gallery entries, which first sounded great but if the user is not able to display a few categories at once I can pretty much dump the idea of using this. 🙁
Hey, I got a similar issue and this already helped a lot. What i am trying to do is querying recordings by id which seems to not work at all.
query_posts("post_type=discography&recordings=2,3,4")
neither does it when i try to with a single id or with multiple term names like
query_posts("post_type=discography&recordings=live,studio")
Is that possible? Would be grateful for some help 🙂
