Hi,
I am currently using the plugin WP-dtree to sort my website according to a custom taxonomy called Topics. I have "Topics" assigned to posts in a number of different post types, including "resources," "animation," "people," and "wiki"
I've set it up so that the taxonomy sorting is working - most posts haven't been assigned taxonomies, but an example of a functional taxonomy page is here: http://rarebit.org/?topics=studios
What I would like to do is design check-boxes, or radio buttons, which filter these results by post type. Ideally, when you check off a box that says "Show only Animation" it would change the query string to http://rarebit.org/?post_type=animation&topics=studios
I suspect that this is possible but I could use some help getting going in the right direction. I'm not sure how I would go about programming these checkboxes and I would be thrilled if this community could offer some guidance.
I am also curious, if anyone knows, if it is possible to show results from across multiple custom post types and if there is an OR operator I can program into the query string? If this is significantly more difficult, I would be fine to design the checkboxes (or radio buttons) so that only one can be selected at once.
Any help is appreciated.
