    I am trying to upload a file with some additional info as post variables.

    in php side i get the file upload properly, but when i do $param1 = $_POST['param1'] i get a blank.

    what am i doing wrong ?

    I would suggest reviewing the samples here, specifically the last chunk of code at the bottom.

    I believe the problem is you need a Content-Disposition header for each name-value pair.
