У меня есть файловый сервер, который правильно проверяет допустимые типы и размеры файлов и помещает файл на сервер. Если загружено несколько разрешенных файлов, они заархивируются и архив помещается на сервер.
Это все работает. Страница является ajax-ified, поэтому вы должны иметь возможность использовать форму во второй раз, но она всегда дает сбой при втором отправлении.
Ответ от upload.php для второго сообщения:
<script language="javascript" type="text/javascript">window.top.window.stopUpload(
null,
"The file you attempted to upload is not allowed: K",
[],
1,
["K"],
[""]);
</script>
