Thing is, it’s my own custom sharing buttons plugin (I know, I know…), which just hooks the buttons onto the_content(). So I should be able to add a conditional check along the lines of:
if ( 'spot' != get_post_type() ) {
...
}
Will try it out.
Ah, it looks like you can access the internal admin functions for link manipulation including wp_insert_link() by including wp-admin/includes/bookmark.php in the script.
Odd that there isn’t a public function to do this, as there is for posts/pages?
