Code

function set_relationship() {

  // Ensure this gets set to something.
  $this->relationship = NULL;

  // Don't process non-existant relationships.
  if (empty($this->options['relationship']) || $this->options['relationship'] == 'none') {
    return;
  }
  $relationship = $this->options['relationship'];

  // Ignore missing/broken relationships.
  if (empty($this->view->relationship[$relationship])) {
    return;
  }

  // Check to see if the relationship has already processed. If not, then we
  // cannot process it.
  if (empty($this->view->relationship[$relationship]->alias)) {
    return;
  }

  // Finally!
  $this->relationship = $this->view->relationship[$relationship]->alias;
}
