I have a custom post, with a custom taxonomy.
When the editor insert a new post I need they to chose a category ( custom taxonomy ).
I read around and I found a conceptual street, but then need some advice to make it real!
I use the hook "save_post".
I check the role, then I check in the $_post variable if received the value of the taxonomy, and if not, I send them back to the page with a message "hey, don't forget to insert bla bla bla...".
First problem: how to make the checks only in the page of my custom post?
Second problem: how to send them back with the allert message?
It make sense... eheheh... only... now the syntax... mmm...
