How would I check if the guid is correct?

 

Thanks

 

EDIT - I checked the posted guid with the js task guid and they match.  I cannot seem to find the difference between my code and the form-keepingstate.php example.  My source code has a lot of dependencies and it is part of a larger web application with many pages and built-in security so posting the full code is probably not a good idea.  Here is what it looks like right now:

 

   $fileguidlist=@$_POST["current_uploader"];
   if($fileguidlist)
   {
      //echo $fileguidlist;
      $guidlist=split("/",$fileguidlist);
      foreach($guidlist as $fileguid)
    {
       if($uploader)
          echo $fileguid;
     $mvcfile=$uploader->GetUploadedFile($fileguid);
     if($mvcfile)
     {     
            echo "myfile=" . $mvcfile->FileName;
            //Rename the uploaded file
            rename("files/".$_SESSION['orgid']."/".$mvcfile->FileName,$_SESSION['curTkt']."~".$mvcfile->FileName);
         }
      }
   }

It is still not getting into the if($mvcfile) block

 

Thanks
