如何将摘要行添加到Drupal视图？

Question

我已经构建了一个视图(Drupal 6.x,Views 2.x).我希望能够在此视图的末尾添加摘要行 - 总计几列,并在摘要行中包含总计.

我怎样才能做到这一点？是否有一些视图数据更改挂钩我可以实现,更改构造的数据(在它获得主题之前)？

(请注意,我无法使用,views_calc因为此视图中的某些数据来自视图关系,views_calc在撰写本文时它不支持.)

几小时后回答我自己的问题......一种方法是实施hook_views_pre_render():

/**
 * Implementation of hook_views_pre_render().
 */
function mymodule_views_pre_render(&$view) {
  if ($view->name == 'myview') {
    // perform calculations on each row
    $pointsEarned = $pointsPossible = 0;
    foreach($view->result as $submission) {
      if (is_numeric($submission->node_data_field_pointsearned_field_pointsearned_value)) {
        $pointsEarned += $submission->node_data_field_pointsearned_field_pointsearned_value;
        $pointsPossible += $submission->node_node_data_field_pointspossible_field_pointspossible_value;
      }
    }


    // insert a 'total' row
    $row = new stdClass();
    $row->node_data_field_pointsearned_field_pointsearned_value = $pointsEarned;
    $row->node_node_data_field_pointspossible_field_pointspossible_value = $pointsPossible;
    $view->result[] = $row;

    if ($pointsPossible > 0) {
      // insert an 'average' row
      $row = new stdClass();
      $row->users_name = 'Average:';
      $row->node_data_field_pointsearned_field_pointsearned_value = round($pointsEarned/$pointsPossible * 100) . "%";
      $view->result[] = $row;
    }
  }
}
