Uploading file and response to user

[Edward Low]

Hi,

How should i allow user to upload multiple files in a page and display
message on the page to inform the client the file is being uploading while
the upload process still in progress? for example user upload 3 files....
then system should response to user while uploading until finish uploaded:
please wait: file 1 is being uploaded.....
file 1 is successfully uploaded.
please wait: file 2 is being uploaded....
file 2 is successfully uploaded.
please wait: file 3 is being uploaded...
file 3 is successfully uploaded.

after this, system redirect user to the another page.


How can this been done?

thanks!

Edward
