I am using SWFUpload to allow users to upload multiple files in any browser. A user can provide custom file names for the files being uploaded. How can I iterate through all the queued files and update the name of the file to the custom name before the file is uploaded.

If I can't change the file name, how do I add a post parameter to each file being uploaded to make the change on the server side? I know how to add parameters for all files but how would I do it for each file?

You can't update the actual name of the file that gets sent in the POST body of the file upload because internally, SWFUpload is using a FileReference which doesn't let you change any of the file's properties before uploading it (and there's no way to get proper upload progress without using a FileReference to do the uploading, so this isn't something that can really be changed).

However, you should be able to add an extra POST parameter per file via the addFileParam function. Its signature is:

addFileParam(file_id:String, name:String, value:String):Boolean

  • So how do I iterate through the files to use the addFileParam to each file? – Dan Apr 24 '12 at 14:20
  • I added an uploadStart function that runs before each file upload and was able to use addFileParam(...) to get the proper information passed. – Dan Apr 26 '12 at 16:02
