progress display for html upload

vitch2002

Hi,
I'm trying to make a progress indicator for a http upload. Impossible say all the posts I've found on it but you've gotta try 😉
Basically, the way I am trying to do it is by submitting the form containing the file to a hidden frame and having a display page with a javascript refresh to provide the user feedback.
The display page does a filesize on the uploaded file and displays this info to the user. Except how do I find the name of the temp file being uploaded? On my windows dev machine the tmp files seem to be called something like this: php65.tmp with the numbers being in hex and increasing with each upload. Something I should be able to work with (ignoring similtanious uploads). But on my live linix machine the temp files are called something like this: phpv3RkDm and I'm not sure what this relates to...
Is there any way to find out the name of the next temp file to be generated? If so then I think I can get this to work at least for one upload at a time (it's just a personal site so shouldn't be too much of a problem).
The other thing I was thinking of was scanning the temp directory for the last modified file and getting the size on that. Could this work as well??
Thanks for any ideas,
Kelvin.

I wish I had some better inmup for you than what I'm about to offer, but first off, just about anthing is possible! 🙂 I like your ideas and think they're probably the most interesting I've seen relating to the particular subject of "monitoring" and http upload.

Anyway, as far as "predicting" the next temp file name in UNIX, I wouldn't know where to start. However, your idea of scanning the directroy for the most recently updated file would do the trick.

For a given user that starts an upload, IMMEDIATELY "associate" the most recently updated file to him.
Track that file's size, thus giving you a basis for a progress monitor.

Yes.. I think that would work. Keep us posted on how the project develops. Good luck!

my only problem is the "IMMEDIATELY"!!
because the php in the page submitted to won't run until the file upload is complete. Too late then 🙁
Although maybe I can submit two forms... One to grab the filename and monitor and one to actually upload the file. Not sure if it's possible to submit two forms from the same page tho... But then I guess I can submit a form in the hidden frame to a pop up to do the monitoring at the same time as submitting the upload form to the hidden frame. hmmm, seems kinda dodgy but I'll get to work on it and see if it works!
If anyone else has got any other ideas or has tried this in the past then let me know...
Thanks for the suggestion,
Kelvin.

... and I'll let u know if it works...

I'm quite sure submitting two forms simultaniously is possible... using javascript if I remember correctly. I'll dig through some notes from about a year back or so and see if I can remember how to do it 🙂
