  1. /**
  2.  * Modifies a node object adding taxonomy terms and, optionally, modifying a

  7.  * @param <type> $vid
  8.  *   The vocabulary ID for the tags.
  9.  * @param <type> $tags
  10.  *   An array of strings to use for the term names.
  11.  * @param <type> $not_found_action
  12.  *   Action to take when terms are not found. Options are: 'ignore' (default)
  13.  *   which will simply not insert that term into the node, 'create' will create
  14.  *   new taxonomy terms, and 'other' will assign the term 'other' for a term that
  15.  *   was not found.
  16.  * @param <type> $fieldname
  17.  *   Optional; a content_taxonomy field machine name. E.g. field_my_tags
  18.  * @return
  19.  *   A node object that can be stored in the database using node_save().
