function mfw_field_widget_process_multiple in Multiupload Filefield Widget 7

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

Mostly copied from drupal core module /module/file/file.field.inc.

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.
