Mapping Terms to Posts in Breadcrumb Trails

In certain site configurations, it makes sense to replace the WordPress built-in term archives with a post (an instance of some post type). Typically, a page (instance of the page post type) is used in place of the term archive. Since version 1.5, Breadcrumb NavXT Paths supports mapping terms to pages (with regards to where the breadcrumb links to). To facilitate this, Breadcrumb NavXT Paths provides a metabox in the term editor for establish this mapping.

Sometimes, the page post type does not make sense for this mapping. In that case, the bcn_paths_map_term_post_args can be used to change the post type that the term editor metabox added by Breadcrumb NavXT displays. Note that this filter was introduced in Breadcrumb NavXT Paths 1.6.0.

The Code

Placing the following code into a site specific plugin, will allow Breadcrumb NavXT Paths to map terms to the post post type:

add_filter('bcn_paths_map_term_post_args', 'my_bcn_paths_map_term_post_args', 10, 3);
function my_bcn_paths_map_term_post_args($args, $term, $taxonomy)
     $args['post_type'] = 'post';
     return $args;

Naturally, this can be modified to specify post types other than post. Should multiple post types be desired, just replace the string 'post' with an array of the post type names. Since this filter affects the arguments sent to get_post, other arguments may be set as well.
