Returning results using a custom taxonomy is easier to do it that it sounds, I will show two ways.
The link method
The first method I think is the easies because it doesn’t require to buil any form create any fields or try to learn complicated API calls. Here are a few examples, you want to add.
- Term name:
- Term id
Traditional method, the web form.
This method is just like the link in that the end result will look just the same, but you are giving the user a way to change the input data. Here is how your form should look like.
<form method="get" id="searchform" action="/"> <label for="s" class="assistive-text">Search</label> <input type="text" class="field" name="s" value="" id="s" placeholder="Search"> <input type="submit" class="submit" name="submit" id="searchsubmit" value="Search"><input type="hidden" name="taxonomy" value="taxonomy"> <input type="hidden" name="term_name" value="term_name"> </form>
Extra: Post Types
- Link: /?s=search+term&post_type=post_type
<input type="hidden" name="post_type" value="post_type">

I was searching for something as easy like this but unfortunately this does’t seem to work. I am using wordpress version 3.3.2. Please reply. No results are returned as the parameters taxonomy & term_name is not used at all
I tested it on version 3.3.2 and it works just fine, taxonomy & term_name was already implemented on this version. Please provide a link to your site and taxonomy & term_name to test.
Well nearly a month later i have returned with some different views which you would be very interested in.
1. Get all results of a certain Custom Post Type.
(The layout will vary as the template has been designed only for the archive-*custom-post-type*.php page)
Here ‘studies_categories’ is the taxonomy for custom post type ‘ccrrc_studies’ and ‘asia’, ‘nacs’, etc. are the various terms for this taxonomy. The terms are created in the dashboard.
‘hierarchical’ => true,
‘labels’ => array(
‘name’ => __( ‘Study Councils’ ),
‘singular_name’ => __( ‘Councils’ ),
‘menu_name’ => __( ‘Councils’ ),
‘query_var’ => true,
‘rewrite’ => array(‘slug’ => ‘studies-categories’)
I am able to get all the posts for a certain custom post type by writing its name in the URL but still no luck with the ‘&taxonomy=studies_categories&term_name=asia’ in the GET Parameters.
Please do provide your setup for the custom post type and taxonomy so i know its an issue with setting the taxonomy & custom post type up.
you need to make the custom post type searchable.
