I am trying to rename a file after it has been uploaded but I am unable to get the file name.  I can get the GUID for the file but not the file name.  Any ideas why $uploader is not returning a phpuploadfile object?

 

Here is how I instantiate the uploader:

                  <form id="form1" method="POST">
                        <?php
                           $uploader=new PhpUploader();
                           $uploader->Name="current_uploader";
                           $uploader->MultipleFilesUpload=true;
                           $uploader->InsertText="Select file(s)";
                           //$uploader->MaxSizeKB=1024000;
                           $uploader->AllowedFileExtensions="*.jpg,*.png,*.gif,*.bmp,*.txt,*.zip";
                           $uploader->SaveDirectory="files/" . $_SESSION['orgid'];
                           $uploader->FlashUploadMode="Partial";
                           $uploader->Render();
                        ?>
                        </form>

Here is where I try to rename the file:

   $fileguid=$_POST["current_uploader"];
   if($fileguid)
   {
      echo $fileguid;
      $uploadedfile=$uploader->GetUploadedFile($fileguid);
      echo "myfile=" . $uploadedfile->FileName;
      if($uploadedfile)
      {
         //Rename the uploaded file
         echo "Renaming file";
         $uploadedfile->MoveTo("./".$_SESSION['curTkt']."-".$uploadedfile->FileName);
      }
   }

The echoes are for debugging.  It echoes the fileguid but then $uploadedfile->FileName is empty.  It never gets to the part that echoes "Renaming file."
