As you can see from the image, I am listing all categories and the cities (taxonomy list).
enter image description here

What I want to do is :

If Car classifieds is selected on cities list show the city name which has car classified on that city. That means if 2 Car Classified is on London should show 'London (2)' (not total number). It is like filtering action.

I have something like

$cat_id = get_category(get_query_var('cat'))->slug; 
wp_list_cats( 'hide_empty=1&hierarchical=1&order=ASC&show_count=1&taxonomy=location&title_li=0&cat=$cat_id' );

Which doesnt work. I feel I am really close to solve this but couldnt manage to do it.

I'm not hundred percent sure but I think the widget in scribu's plugin, Query Multiple Taxonomies, works exactly as you described. You can find plenty of resources on the subject on his blog.

This plugin lets you do faceted search using multiple custom taxonomies.

It has a drill-down widget with multiple display modes.

Said widget is easily customizable via template files (no PHP knowledge required).

  • I didnt say yo have to use the plugin. you can simply check out the source code. The method what scribu originally used is in the core now because of him. The only thing Im not sure about ist the counter as you described but his widget does that. Check out the WP_Query docs for multiple taxonomy queries
