== Description ==
Add support for date-based taxonomy archives.
Includes a function for rendering an unordered list of years with months, linked to corresponding date-based taxonomy archive, nested therein.
**This plugin is intended for use by plugin and theme developers. It simply adds support for date-based taxonomy archives, but has no native user interface.**
== Installation ==
1. Upload date-based-taxonomy-archives to /wp-content/plugins/.
2. Activate plugin through the WordPress Plugins menu.
3. Go to Settings > Permalinks and click _Save Changes_ to refresh permalinks.
== Frequently Asked Questions ==
= How do I use this plugin? =
Add the function `date_based_taxonomy_archives()` to any template element that appears on a taxonomy archive. The function accepts an array containing the following arguments:
* `taxonomies` - array of taxonomy slugs.
* `show_post_counts` - boolean value specifying whether or not to display show counts in parenthesis after archive links.
* `limit` - integer specifying the number of archive links to show. Omit to show all archive links for the specified taxonomy.
* `before` - output to display before archive link.
* `after` - output to display after archive link.
* `echo` - boolean value specifying whether to echo or return archive links.
= What filters does this plugin include? =
* `date_based_taxonomy_archives_args` - applied to arguments passed to `date_based_taxonomy_archives()` at runtime.
