I am trying to create a plugin that will only list posts in a category that meet a criteria I've defined in an external table.
So far the admin section has gone ok, I have my list of criteria available to select and assign to posts.
Now when a category page is displayed I only want to show posts that meet the criteria. So where or how do I intercept the list of posts and filter it before it displays?
I thought I was onto something yesterday, but I can't remember it know.
