Code

function themekey_taxonomy_tid2tid_and_parents($tids) {

  /* It might be a bit confusing why the callback for 'taxonomy:tid_and_childs' is
   * called themekey_taxonomy_tid2tid_and_parents() and detects the parents for a
   * given tid. But it's correct to invert the logic here.
   * Example:
   * Term 17 has a child 27. The ThemeKey rule is "taxonomy:tid_and_childs = 17".
   * So if curent tid is 27, this callback function has to return it's parent 17
   * to cause a match in the rule engine.
