function commerce_order_preprocess_views_view in Commerce Core 7

Implements hook_preprocess_views_view().

When the line item summary and order total area handlers are present on Views forms, it is natural for them to appear above the submit buttons that Views creates for the form. This hook checks for their existence in the footer area and moves them if necessary.

Code

function commerce_order_preprocess_views_view(&$vars) {
  $view = $vars['view'];

  // Determine if the line item summary or order total area handler is present
  // on the View.
  $has_handler = FALSE;
  foreach ($view->footer as $area) {
    if ($area instanceof commerce_line_item_handler_area_line_item_summary || $area instanceof commerce_order_handler_area_order_total) {
      $has_handler = TRUE;
    }
  }

  // If one of the handlers is present and the View in question is a form...
  if ($has_handler && views_view_has_form_elements($view)) {

    // Move the footer area into a row in the View positioned just above the
    // form's submit buttons.
    $vars['rows']['footer'] = array(
      '#type' => 'markup',
      '#markup' => $vars['footer'],
      '#weight' => 99,
    );
    $vars['footer'] = '';
