Does anyone know how to add a variable in to pull the parent category into the title tag - so wwhen using this wp-admin/admin.php?page=wpseo_titles&settings-updated=true#top#template_help - I might be able to add %%category_parents%% before my title end s with %%sep%% %%sitename%%
I know I will probably need to set up an ID for it like so in wordpress-seo/inc/wpseo-functions.php:
'%%category_parents%%' => wpseo_get_terms( $r->ID, 'category_parents' ),
but where and what would I add it so it can get..?
any help much appreciated!
