Get the latest taxonomy/category?

by

I’m designing a custom magazine theme, where categories are used for different sections, and I created a custom “edition” taxonomy.

The editor will create a new term in that taxonomy for each new edition published, i.e. the number of the issue.

How can I query the latest “edition”, so I can combine it with each category and then publish only the posts that belong to the newest edition?

Something along the lines on:
?edition=34&cat=studies

The latest edition should always be the term in that taxonomy with the highest term_id, right? Query get_terms and find the latest edition, then use that term to build the rest of your query…

$edition = get_terms('edition','orderby=none&order=DESC&number=1');
$latest_edition = $edition[0]->slug;

Then you can either modify the current query, if that’s what you want to do:

global $wp_query;
$wp_query->set('edition',$latest_edition);

Or use it to build new queries:

$studiesposts = get_posts('category_name=Studies&edition='.$latest_edition);

If you have your permalink structure set up, it should also work to build urls for new links, like this:

http://yourdomain.com/edition/34/category/studies
