Update
From reading the answers, i think i didn’t make myself clear, so i try to post it again.
I register taxonomies from data from parsed xml files. The arguments passed should be absolutely correct. What i wanted to know is on which of the arguments of the register_taxonomy() function the sanitize_title() function get’s called. I currently got an error and need to figure out which of the parameters is wrong.
One Trick Pony is right, register_taxonomy() does not handle arrays.
First: Sorry, if i wasted your time.
The problem couldn’t have been guessed by anyone and was lying in the middle of my class. I simply build an array where i pushed all needed stuff into. This array was rebuilt before i pushed it into the
register_taxonomy()function. There i simply forgot to unset those parts i didn’t need anymore.@MikeSchinkel @One Trick Pony – please add some answer here, so i can upvote you for your efforts. Thanks to everybody 🙂
