Code

function views_form(&$form, &$form_state) {

  // The view is empty, abort.
  if (empty($this->view->result)) {
    return;
  }
  $form[$this->options['id']] = array(
    '#tree' => TRUE,
  );

  // At this point, the query has already been run, so we can access the results
  // in order to get the base key value (for example, nid for nodes).
  foreach ($this->view->result as $row_id => $row) {
    $line_item_id = $this
      ->get_value($row, 'line_item_id');
    $quantity = $this
      ->get_value($row, 'quantity');
    $form[$this->options['id']][$row_id] = array(
      '#type' => 'textfield',
      '#datatype' => 'integer',
      '#default_value' => round($quantity),
      '#size' => 4,
      // The line item database schema limits the quantity to 8 numerals for
      // integer quantities. For fractional quantities, we'd support decimal
      // places, but without knowing if a site supports them or not, the
      // safest option for this field's supported input length is 8; but a
      // malicious user could still create a problem insert by using the max
      // quantity on a price so it breaks the total allowed amount. If a site
      // has been customized to support larger quantity values, this property
      // can still be overridden via a form alter.
      '#maxlength' => 6,
      '#line_item_id' => $line_item_id,
      '#attributes' => array(
        'title' => $this->options['label'],
