Draggableviews processing functions. Rough summary of what functions in this file do:

Code

function _draggableviews_click_sort(&$info) {

  // Check permissions.
  if (!user_access('Allow Reordering')) {
    drupal_set_message(t('You are not allowed to reorder nodes.'), 'error');
    return;
  }

  // Check if structure is locked.
  if ($info['locked']) {
    drupal_set_message(t('The structure is locked.'), 'error');
    return;
  }

  // If the items to display per page are limited we load the entire view.
  $pager = $info['view']->query->pager;
  if (isset($pager->options['items_per_page'])) {
    _draggableviews_reload_info($info, DRAGGABLEVIEWS_DBQUERY_LIMIT, 0, $pager->options['offset']);
  }

  // First bring all child nodes down to the root level. We can't keep the hierarchy information
  // because the nodes have been mixed up thoroughly.
  if (isset($info['hierarchy'])) {
    foreach ($info['nodes'] as $nid => $values) {
      $info['nodes'][$nid]['parent'] = 0;
      $info['nodes'][$nid]['depth'] = 0;
    }
  }

  // Assign ascending numbers
  _draggableviews_ascending_numbers($info, $pager->options['offset'], TRUE);
  _draggableviews_save_hierarchy($info);

  // Re-execute view with original page settings.
  _draggableviews_reload_info($info, $pager->options['items_per_page'], $pager->current_page, $pager->options['offset']);
