file_field_widget_process_multiple($element, &$form_state, $form)

An element #process callback for a group of file_generic fields.

Adds the weight field to each row so it can be ordered and adds a new AJAX wrapper around the entire group so it can be replaced all at once.

<?php
function file_field_widget_process_multiple($element, &$form_state, $form) {
  $element_children = element_children($element, TRUE);
  $count = count($element_children);

  foreach ($element_children as $delta => $key) {
    if ($key != $element['#file_upload_delta']) {
      $element[$key]['_weight'] = array(
        '#type' => 'weight',
        '#delta' => $count,
        '#default_value' => $delta,
      );
    }
    else {
      // The title needs to be assigned to the upload field so that validation
      // errors include the correct widget label.
      $element[$key]['#title'] = $element['#title'];
      $element[$key]['_weight'] = array(
        '#type' => 'hidden',
        '#default_value' => $delta,
      );
    }
  }

  // Add a new wrapper around all the elements for AJAX replacement.
  $element['#prefix'] = '<div id="' . $element['#id'] . '-ajax-wrapper">';
  $element['#suffix'] = '</div>';

  return $element;
}
