Validates whether an argument is a flaggable/flagged object.

Code

function get_flag() {
  $flag_name = $this
    ->_get_option('flag_name', '*relationship*');
  if ($flag_name == '*relationship*') {

    // Pick the first flag mentioned in the relationships.
    foreach ($this->view->relationship as $id => $handler) {

      // Note: we can't do $handler->field, because the relationship handler's init() may overwrite it.
      if (strpos($handler->options['field'], 'flag') !== FALSE && !empty($handler->options['flag'])) {
        $flag = flag_get_flag($handler->options['flag']);

          return $flag;
        }
