Multiple File Uploads

[aknapple]

When using multiple file uploads how can you tell the last file has been uploaded?

Thanks,
Allen

Hello Allen

As you can see in the documentation

you can use the property FileUpload.FileNames

FileUpload.FileNames.Names[i] contains the upload name, and FileUpload.FileNames.ValuesByIndex[i] the output complete path.

I don't understand how. Can you give me an example? I am looking for a way to know the entire upload is complete. I was looking for something like an OnDone event. OnComplete doesn't work because it gets called for each file downloaded. There is nothing to tell me it's the last file. I'm not sure how having the list of filenames and paths helps because I don't know how many files the user is going to select.

Thanks,
Allen

Hi

Check the JQueryDemo_V2 in the upload frame

Hi,
I have the same need for a final OnComplete event.
I've dig throught the demo code with no response, this code is executed for each file.
So one must maintain an external index to avoid processing several time the same.
Thank you if you can provide a simpler solution.

Or maybe show I use UploadingFileList property?

Hi DidierL,

You can use the follow code:

delphi code

procedure TIWForm3.IWAppFormCreate(Sender: TObject);
begin
  IWCGJQFileUpload1.JQFileUploadOptions.OnComplete.Condition:= Format('(%s_JQObj._uploadingList._filelist.length == 0)',[IWCGJQFileUpload1.JQHTMLName]);
end;

The OnComplete event will fire only when finish the last file upload.

Thanks!
It is really powerful.

The code appears to be incorrect. Please advise correction

Code: Select all

procedure TIWForm3.IWAppFormCreate(Sender: TObject);
begin
  IWCGJQFileUpload1.JQFileUploadOptions.OnComplete.Condition:= Format('(%s_JQObj._uploadingList._filelist.length == 0)',[IWCGJQFileUpload1.JQHTMLName]);
end;

Also, How can I display an error message from within the IWCGJQFileUpload1BeforeSubmitEx event
