在tag.php显示自定义文章分类文章

前提是要在注册文章类型的时候绑定taxonomies为post_tag

‘taxonomies’  => array(‘post_tag’),

/**
 * Advanced version that works with multiple custom post types
 * and handles both tags and categories
 *
 * @param WP_Query $query The WordPress query object
 */
function include_all_post_types_in_archives($query) {
    // Only modify the main query on the frontend
    if (is_admin() || !$query->is_main_query()) {
        return;
    }
    
    // For tag or category archives
    if ($query->is_tag() || $query->is_category()) {
        // Get what taxonomy we're currently viewing
        $taxonomy = $query->is_tag() ? 'post_tag' : 'category';
        
        // Find all post types that have this taxonomy registered
        $post_types = array();
        $registered_post_types = get_post_types(array('public' => true), 'objects');
        
        foreach ($registered_post_types as $post_type) {
            $post_type_taxonomies = get_object_taxonomies($post_type->name);
            
            // If this post type has the current taxonomy registered
            if (in_array($taxonomy, $post_type_taxonomies)) {
                $post_types[] = $post_type->name;
            }
        }
        
        // Only modify the query if we found post types
        if (!empty($post_types)) {
            $query->set('post_type', $post_types);
        }
    }
}
// Uncomment this line to use the advanced version instead
add_action('pre_get_posts', 'include_all_post_types_in_archives', 10);
