I don't see how this could work: IIRC the
file upload happens as part of the POST
request to the web server, and no javascript
runs while a request is being made.

Could you post a link to ehe version you have
seen working with ASPs, so we can see how
they have implemented the feature?

Anyway: the feature shouldn't be ASP specific
if it is implemented with javascript. Client-
side JS should work that same irrespective
of which server-side scripting language is
being used.

He probably saw a Java applet, not javascript.

well i also saw one he mentioned on driveway.com ..... when we uploaded file there there was a popup window which would tell about the progress. and i am sure that it was not an applet ... now they have closed free service so this cannot be tested.

This discussion has been here a long time ago if I remember correctly.

The point is that a POST operation cannot do anything serverside untill the POST is complete.

So the only thing that I think could be done is to have a custom-made upload-service that the form is POSTed to.

When the form is submitted javascript opens a new browser window and points it to the upload-service with the name of the uploaded file (or IP or something to identify this browser by). That window can then refresh itself every x seconds, and query the upload-service to ask it how much of the file has been received.

Complex but possible.

Wether this is also usefull is another matter. If files get so big uploading them takes so long that it warrants a status indicator then I think it's time to start using FTP instead.

Did anyone every find a Linux/PHP solution for the upload progress bar?

Better just use FTP programs to upload large files, that gives you a progressbar and saves you oodles of time and resources.

Well, to continue a very long discussion....

I found an ASP example here: http://www.aspupload.com/manual_progress.html

Now, my thoughts are similiar to a previous poster. You just have to make the popup window do the following.

-Reload every x seconds.
-know the name of the file being uploaded
-know the total size that the file should be
-run a php script that checks the total file size progress.

the only challenge is knowing what the total file size is. Off the top of my head I do not know of a way to catch that property in javascript to send it to the progress page

There are plenty of uses for this feature. I know there is a point where you say you should use ftp. however, if the application were a backroom for a clients website, you probably don't want them using ftp.
