Hi. This isn’t something that WP Biographia can do. The selection and display of posts is under the control of the WordPress Loop that your theme uses. Under normal circumstances, by the time the plugin is being called, you’re already in the Loop and the posts have already been queried and selected. Also, the way in which WP Biographia works is to hook into the WordPress the_content and/or the_excerpt filters so when the plugin is called, the current post or page is already being displayed.
This isn’t a shortcoming of the plugin, it’s just the way in which WordPress tries to separate plugin functionality from display functionality (via the current theme).
But what you can do is to write a custom page template that queries for all the users on your site, loop through those users and for each user, perform a custom Loop that selects the latest post for that user, emits the plugin’s Biography Box via a template tag and then call your theme’s single post template.
If you take a look at this Gist – https://gist.github.com/vicchi/5553170 – you’ll see a working example of how to do this.
A few notes of caution. The Gist is based on the stock WordPress Twenty Ten theme and assumes you’re running WordPress under PHP 5 (there’s a couple of changes you’d need to make if you’re still running PHP 4 for some reason). I’ve tested this on a local install under Twenty Ten and it works. But you’re probably using a different theme so you may need to make some changes to reflect the way in which your theme works.
Anyhow, hope this helps.
