Plugin Description
This plugin allows you to display posts that appear in both of the two specified categories.
It will display these posts on a custom page in your template called categories.php (if you produce one) or your archive.php page, failing that it will fallback to index.php.
Once installed you also have available two additional theme tags:
<?php is_dual_categories(); ?>
This returns true or false to determine if the posts are being filtered by two categories.
<?php dual_cat_titles(); ?>
This is the dual category equivalent to single_cat_title() used on the archive page. By default this outputs both category names with �and� between them.
There are two options:
- Specify Which category:
show the first (1) , second (2), or both (0) categories:
<?php dual_cat_titles( 1 ); ?>
- Specify what appears between them:
If showing both categories choose the text to go between them (including spaces):
<?php dual_cat_titles( 0 , ' and '); ?>
An example of its use:
The URL reads: http://www.mysite.com/index.php/categores/india/photographs/
The code reads:
<strong><?php dual_cat_titles( 2 ); ?> from <?php dual_cat_titles( 1 ); ?></strong>
The page displays: Photographs from India
Changing the dual category base
From WordPress 2.7 this plugin adds a new field to the permalink settings page to set the dual category base. So if you want to /country/india/photo/ enter country in the dual category base.
