Sharing a custom taxonomy - No posts?

Question

I've been writing up some code which enables two post types to share a custom taxonomy. From the admin side, it works fantastically - but for some reason, when I look at the taxonomy archive itself on the site,

/country/{country} , despite the fact that there are two posts (one from each type) in the taxonomy, it comes back with 'No posts found' but not a 404 error. I wonder if I've missed something to make it work - my code is below.

register_taxonomy(
        'country',
        array('hotels', 'attractions'),
        array(
            'label' => __( 'Country' ),
            'hierarchical' => true,
            'sort' => true,
            'args' => array( 'orderby' => 'term_order' ),
            'rewrite' => array( 'slug' => 'country' )
        )
    );

Answer 1

As the page is returning with "no posts found", it's possible that whatever template page is generating term archives isn't including your custom post types in its query.

If you take a look at the template that should be easy to see.

Answer 2

Your will need to edit the taxonomy page. By default it will only get 'post' not custom post types.

Adjust the query which has run on the page with the right posttypes. http://codex.wordpress.org/Class_Reference/WP_Query#Type_.26_Status_Parameters

Answer 3

Not sure what do you mean by "two post types to share a custom taxonomy". As I understand correct you can try to add to functions.php something like this:

function customposttype_rewrites($wp_rewrite) {
    $newrules = array();
    $newrules['country/([^/]+)/?$'] = 'index.php?name=$matches[1]&taxonomy=country&term=$matches[1]';

    $wp_rewrite->rules = $newrules + $wp_rewrite->rules;
}
add_filter('generate_rewrite_rules', 'customposttype_rewrites');
