Czołem, mam taki skrypt na upload pliku wraz z paskiem postępu, lecz coś mi ten pasek nie działa (nie wyświetla go). Czy jest to prawidłowy skrypt?
<?php
//get unique id
?>
<?php
//process the forms and upload the files
if (isset($_POST['Submit'])) {
//specify folder for file upload
$folder = "";
//specify redirect URL
$redirect = "upload.php?success";
//upload the file
//do whatever else needs to be done (insert information into database, etc...)
//redirect user
}
//
?>

Jeśli ten skrypt się nie nadaje, to jak zrobić taki pasek postępu?.
Myślałem żeby np co 1 ms sprawdzać ile bajtów z danego pliku znajduje się na serwerze i obliczać na podstawie tego procent.
Może da się jakoś inaczej?, proszę o porady. Nie chciałbym pisać tego we flashu.
