I'm trying to create/add a widget to a client's website that lists all non-admin authors and links to their posts. I've been able to do that but one of the authors posts, almost exclusively, using a CPT that I created for recipes so the widget does not link to any of her posts.
Because of this and because it's possible that a similar situation could arise in the future with another CPT I would like my widget to query every post type to see if any given author has published an entry with that post type and then link to an archive page displaying all of there posts, regardless of the post type.
I've searched the codex, various plug-ins, Google searches, etc... but haven't found a solution to this specific issue.
I created a plug-in for this custom widget and am including the code below. As a side note, I'm also having trouble getting the exclude_admin argument to work in the widgets section of the plugin. Any help with that would be appreciated as well. Thanks!
