title: Submit custom POST variables with each file
body: <p>I am trying to send custom POST variables with each uploaded file. </p>
  
  <p>I have it set up so that each file has 2 fields where users can enter tags and a description for that file.</p>
  
  <p>The code I am using is </p>
  
  <pre><code>uploader.bind('UploadFile', function (up, file) {
      $.extend(up.settings.multipart_params, {
          'tags': $('#tags_' + file.id).val(),
          'description': $('#description_' + file.id).val()
      });
  });
  </code></pre>
  
  <p>The above code seems to work for every file except the first.</p>
  
  <p>Is this the proper way to send custom post data for individual files?</p>
