Simple PHP upload progress meter using Prototype
Sunday July 6, 2008
The uploadprogress extension is fairly simple to use - but it is important to note that on some PHP configurations it doesn't function correctly and only returns a progress of 100%.
The JavaScript uses David Stone's method for displaying percentage bars but you can modify the onCreate, onUpdate and onComplete callbacks if you want to use your own.
1) You will need uploadprogress >= 0.3.1 (0.3.0 does not seem to work for me), to build it from source (don't forget to restart your webserver after installing):
cvs -d :pserver:cvsread@cvs.php.net:/repository checkout pecl/uploadprogress
cd pecl/uploadprogress && phpize && ./configure && make && sudo make install
2) Progress tracking is automatically enabled if you have a field named UPLOAD_IDENTIFIER with a unique ID in your file upload form:
<input type="hidden" name="UPLOAD_IDENTIFIER" value="<?php echo $uploadID; ?>" id="uploadIdentifier" />
3) You retrieve the upload progress with your UPLOAD_IDENTIFIER (obviously these calls will be AJAX requests): $data = uploadprogress_get_info($uploadID);
Once the upload is complete the extension will remove the temporary file and further info calls will return null.
That's it!

@Jonu: What version of the uploadprogress extension are you using?
-- Don on 2 September 2008
Don.
I installed your sample code on my server because I’d like to integrate it into an uploader for artists. It initially barfed as the uploadprogress extension was nor present. This I installed as per your instructions, although I had to first “yum -y install php-devel” just to get phpize.
Now the script works except the progress bar shows no actual progress, just goes from 0% to 100% partway thru the upload. Also don’t get the uploadSpeed displayed.
Any thoughts as to what I might be missing?
PS. This runs on a PLESK managed server, PHP 5.2.6, Zend engine 2.2.0 and presumably the latest version of uploadprogress as per the install method.
(how do I actually determine the version short of downloading a tarball?)
Thanks,
B.

Do you have the source of 0.3.1? or which ever version you have.
Thanks

Ok i figured out why it did not work. Try disabling Suhosion extension if installed. Then version 0.9.x will work just fine.
Hope this helps.
Cheers

In that directory and in what time do you upload the file to the server?
