wp-all-posts-for-any-term-in-a-taxonomy.php | |
This is an example showing a hook used to add the ability to use "any" as a term to match all terms for a taxonomy. | |
It will run as a standalone file in the root of a WordPress 3.0 install with a URL that looks like: | |
http://example.com/wp-all-posts-for-any-term-in-a-taxonomy.php | |
It was written to address this question: | |
http://lists.automattic.com/pipermail/wp-hackers/2010-July/033465.html | |
Be sure to edit it to change the values for $post_type and $taxonomy to match the ones you need. | |
