Hi. I have a form where we're allowing members to submit content. The form submission creates new posts in our "Guides" custom post type. If I have a custom taxonomy, let's say "Guide Types," how would I set up a form such that a user-submitted "guide" automatically (invisibly) gets assigned one of my "guide types" taxonomy terms?
I know how to set this up using checkboxes for the user to select, is there anyway to populate this yet hide it from the user?
