I've posted the documentation for SWFUploadField here: http://doc.silverstripe.com/doku.php?id=swfuploadfield

Hello,

Thanks for your interest in the SWFUpload module. The SWFUploadFileIFrame field is useful for filtering out unwanted file types and sizes and displaying a progress bar for large files, but one thing it cannot do is overcome the (annoying) issue of having to save a new record before adding a file. The reason is because your file object needs an "ownerID" to make the correct association with your DataObject class. Until the record is saved, that ID of course, does not exist.

If you're looking for a better way of handling this issue, I'd recommend using the DataObjectManager. Though it doesn't have a "fix" for the problem, it is handled in a much cleaner way with clear language to the user. For instance, if your DataObject has a File relation called "Image", the save button on a new record will read "Save and add Image" -- as opposed to a standard CTF, which will advance the user to a new record without any indication that a file has not been added.

Try it out!

I guess the documentation has been moved, but all links seem to point back to this same dead page.

Not sure where to submit bugs/fixes, so UncleCheese direct me if needed.

Portability issue with SWFUploadFileIframeField:

The RelativeLink method returns a url that is not entirely portable and was causing uploads to fail with a 404 on a site we have installed in a subfolder.

The fix was to replace

public function RelativeLink($action = null)
   {
      if($action === null) $action = "index";
      return "/swfuploadfile/$action/".$this->urlParams['Class']."/".$this->urlParams['ID']."/".$this->urlParams['Field'];
   }

with

public function RelativeLink($action = null)
   {
      if($action === null) $action = "index";
      return "swfuploadfile/$action/".$this->urlParams['Class']."/".$this->urlParams['ID']."/".$this->urlParams['Field'];
   }

removed the "/" from the beginning of the return.
