A WordPress site I'm doing a redesign for has around 1.400 posts by approximately 30 different authors. Unfortunately the authors of the posts have so far been entered as a custom field within the post, and not as separate authors in WP.
I'd like to transfer this to the 'proper way', where each post has an author attached to it, since this would make it possible to display more posts by each author without resorting to plugins like Search Everything.
Does anybody know of a script that could look through all the posts, search for the custom field containing and author and create that author, and then link the post to that author? (I know, long shot...)
Is that even possible or is there an another way apart from going through 1.400 posts and changing them by hand?
