add_action(\'save_post\',\'set_post_default_category\', 10,3);
function set_post_default_category($post_id, $post, $update){
  if($update) return; //only want to set if this is a new post!
  if(\'post\' !== $post->post_type) return;  //only set for post_type = post!
  $term = get_term_by(\'slug\', \'my-custom-term\', \'category\');//get the default term using the slug, its more portable!
  wp_set_post_terms( $post_id, $term->term_id, \'category\', true );
}
