function theme_views_tree in Views tree 6.2

Same name and namespace in other branches

1. 6 views_tree.module \theme_views_tree()
2. 7.2 views_tree.module \theme_views_tree()

Theme function for the tree style plugin.

We need to do some weirdness that makes more sense as a theme function than as a template.

function theme_views_tree($view, $options, $rows, $title) {
  $result = $view->result;

  $options['parent_field_property'] = $fields[$options['parent_field']]->field_alias;

  // Normalize the top level of records to all point to 0 as their parent
  // We only have to do this once, so we do it here in the wrapping function.
  $parents = array();

    $parents[] = $record->{$options}['main_field_property'];
  }

    }
  }
  return $title . theme('views_tree_inner', $view, $options, $rows, $title, $result, 0);
