Monitoring upload progress and completion

I am having a problem to do with monitoring whether the upload completes successfully or not. I have been using the following code to control what action and redirect pages are used:

iu.addParam("Action", "http://domain.com/action.php?var1=1&var2=2");
iu.addParam("RedirectUrl", "http://domain.com");

I assumed the action page was only loaded (like the redirect page) on a successfully completed upload, but this does not appear to be so, so when a user starts uploading then cancels or it errors the action script will still be run. This would be fine, but i can't seem to find a variable that is acccessible by the action script that defines whether the upload completed successfully, is there one? If not, the alternative appears to be to use the following code in place of the addParam action option above:

<script type="text/javascript">
function ImageUploader_Progress(Status, Progress, ValueMax, Value, StatusText)
{
    if (Status=="COMPLETE"){
        //We redirect to galery.aspx page when upload process is completed
        window.location = "action.php";
    }
}
</script>
.....
iu.addEventListener("Progress", "ImageUploader_Progress");

Presumably this would then ensure that action.php was only run on successful completion of an upload? This would be great, however i can't work out how to pass custom variables into this function? My action script needs a large number of other variables to function correctly (hence the ?var1=1&var2=2 in the action param). One would assume using the second method one would need something like the following code, which would presumbly give me access to the added fields from action.php:

<script type="text/javascript">
function ImageUploaderID_BeforeUpload() {
  getImageUploader("ImageUploader1").AddField("var1", "");
  getImageUploader("ImageUploader1").AddField("var2", "");
}
</script>
...
iu.addEventListener("BeforeUpload", "ImageUploaderID_BeforeUpload");

The problem now is how do i get the variable values for var1 and var2 into the addfield arguments within the javascript function? Can i add custom variables to the ImageUploaderID_BeforeUpload function so i can add varibles at the addeventlistener stage or is there another way to do it?

Thanks so much, i very much look forward to hearing from you!

How does the action script know whether the upload was successful? So a user is uploading 10 pictures lets say and he clicks cancel after picture 5. It then runs the actionURL, even though the user clicked cancel. I have it set to only run the relevant actions if move_uploaded_file is successful, so in this case the first five pictures would be successful and so it would add those five to their gallery and not the remaining ones.

Assuming if a user presses cancel they want to cancel the whole upload and not upload any pictures then how do you do that in the actionscript as there doesn't appear to be any variables to define whether it completed successfully/was cancelled etc?

I would really appreciate some help on this, thanks,

I have added the FilesPerOnePackageCount and related methods to allow for single file uploads so i can enable the resume feature, which appears to be working fine. This should hopefully solve some of my users problems. I now have one issue remaining:

At the end of successful upload (as well as obviously moving the uploaded files to their correct locations) i create a number of picture banners and related gallery images which involve a number of php functions using GD. This only needs to be done once after all the pictures have been uploaded so having it in the actionscript is not a good idea as it will then run after every single picture.

The only alternative is to somehow run these php functions from within the ImageUploader_Progress or afterupload functions, the problem with this obviously being that i can't run php scripts transparently from within javascript.

So my question is:

Assuming i am uploading one file at a time to allow for resuming, how do i run a php script, after the upload has finished, that will definitely run irrelevant of whether it errors/is cancelled or completes successfully, without putting it into the actionscript and making it run after every single picture is uploaded?

thanks very much,

Dave

Is there an alternative or additional way that would allow actions to be run at the end irrelevant of whether it errored or was cancelled?

Thanks,

As i say i need to run a script at the end of the upload, whether that's a successful completion/cancel/error?

Using the ImageUploader.Error poses the same problem as i can't call php functions from within Javascript.

Is there any way of running something at the end of uploading, when successful/errorred or cancelled, (without having to physically redirect the user away from the upload page after error/cancellation)?

I would really appreciate some help on this,

Thanks,

Dave
