Chciałbym zaimplementować od swojej aplikacji uplaoder ze strony http://www.johnboy.com/php-upload-progress-bar/ jest do dość łatwe a pasek działa bez problemów. jeśli zauważycie w demo to jak plik zostanie wysłany aplikacja wraca do położenia początkowego. A ja bym chciał aby po wysłaniu pliku przeszła do innej strony czy też ustawiła coś w zmiennej sesyjnej lub wyświetlenie napisu i nie odświeżania strony. Ale gdzie to zmienić? Nie widzę tu żadnego refresh'a jeśli nawet dopisze kod za napisami:
[PHP] pobierz, plaintext 
  1. //do whatever else needs to be done (insert information into database, etc...)
[PHP] pobierz, plaintext

to owszem kod się wykona ale mimo wszystko stronka wraca do pozycji startowej czego ja bym nie chciał. Proszę o pomoc w tej sprawie.
Aby było łatwiej to wrzucam pliki z kodem:
plik -upload.php
[PHP] pobierz, plaintext 
  1. <?php 
  2. //get unique id
  3. $up_id = uniqid(); 
  4. ?>
  5.  
  6. <?php
  7.  
  8. //process the forms and upload the files
  9. if (isset($_FILES["file"])) {
  10.  
  11. //specify folder for file upload
  12. $folder = "../Files/"; 
  13.  
  14. //specify redirect URL
  15. $redirect = "upload.php?success";
  16.  
  17. //upload the file
  18. move_uploaded_file($_FILES["file"]["tmp_name"], "$folder" . $_FILES["file"]["name"]);
  19.  
  20. //do whatever else needs to be done (insert information into database, etc...)
  21.  
  22. //redirect user
  23. //header('Location: '.$redirect); die;
  24. }
