I am creating an app where I need to upload file using HTML input type="file" to a PHP server,when I upload the file to the PHP link without progress bar its working fine but when i add progress bar count script using ajaxform its unable to upload the file to the PHP server while this progress bar code works fine for this online test server, http://posttestserver.com/post.php.

I am not getting what is the actual issue as I am not aware of PHP code and my friend is not aware of HTML code,my friend is saying there is nothing to do from his end as it is working fine without progress bar script. I had tried all possible progress bar script available in the web.please help me out how to solve it with progress bar count.

I have to agree with your friend. If it's working without the progress
bar, it's probably not a PHP problem.

However, you also haven't provided sufficient information for any more
assistance. For instance - did you change any PHP code from the working
to the non-working version? Do you get any errors - either at the
browser (javascript) or the server (php)? Are you sure the scripts
you're using work with the server's version of PHP? What are the
differences between the test and production servers (i.e. PHP versions,
operating system, etc.)?

Lots of unknowns here. You need to do some debugging to see just where
the problem lies. The answers to these questions should help you know
where to start looking.

In order to actually track the progress of the download, you're going to
have to do all the heavy lifting that the browser and server is doing
for you. Most likely this would be a java applet that you'd have to
write. If you think about it, the server has to has no knowledge of the
byte stream being sent to it by the browser. It's my understanding that
if you send the actual length of the file to be transferred down to the
browser, it can display a progress bar.

The reverse is not true. If you use the <input> tag, there's no
provision to tell the server in the tag how long the transfer would be.
And once it starts sending the file, the server can't communicate with
the browser until it's complete.

If this is a *must have*, I'd look at other tools besides php to
transfer a file with a progress bar. You'll most likely have to code it
by hand.

A quick and dirty workaround is to unhide an animated GIF of clock hands
or rotating dots or whatever but it won't have any correlation to what's
being transferred. But it will give the user feedback that something is
happening.

It seems your problems are more related to the client-side library you
are using. You should consider asking in a related newsgroup/forum (the
more specific, the better).

Hmm.

This is an interesting idea that I did not know about. Will surely have
to give it a try at some point.

An alternative to this are chunked uploads, as used by plupload[1], for
instance.

No, before the file upload starts, the browser sends the file size to
the server. And they CAN communicate; see the APC PECL extension.

It can easily be done with the APC extension and some javascript.

Interesting - they finally implemented this in base PHP.

I admit I didn't pay a lot of attention to it as I've been using APC for
quite a while and wasn't looking for anything else.

I would have to agree. Technically, it is possible to track a file
upload to a PHP server without using any PHP. (There is a new JavaScript
interface to track the upload progress, but it isn't supported in all
browsers.)

That's an AJAX error message, and has nothing to do with PHP. You need
to be following up in a javascript newsgroup.
