I have a HTML with a form in it like this:

<html>

<head>
  <script type="text/javascript" src="js/jquery-1.8.3.js"></script>
</head>

<body>
  <form action="accept-file.php" method="post" enctype="multipart/form-data" id="theform">
    Your Photo: <input id="thefile" type="file" name="photo" size="25" />
    <input type="button" name="submit" value="Submit" onclick="submitform();"/>
  </form>
</body>

<script>

  function submitform()
  {
    data = $('*').serialize();

    $.post(
      'http://localhost/banksoal/1.0.0/accept-file.php',
      data
    );
  }

</script>

</html>

and the .php script like this:

        <?php
  //if they DID upload a file...
  if($_FILES['photo']['name'])
  {
    print_r($_FILES['photo']);
    $message = 'default message';

    //if no errors...
    if(!$_FILES['photo']['error'])
    {
      //now is the time to modify the future file name and validate the file
      $new_file_name = 'd:\\' . '--test-- '.basename($_FILES['photo']['name']); //rename file
      if($_FILES['photo']['size'] > (1024000)) //can't be larger than 1 MB
      {
        $valid_file = false;
        $message = 'Oops!  Your file\'s size is to large.';
      }
      else
      {
        $valid_file = true;
      }

      //if the file has passed the test
      if($valid_file)
      {
        //move it to where we want it to be
        move_uploaded_file($_FILES['photo']['tmp_name'], $new_file_name);
        $message = 'Congratulations!  Your file was accepted.';
      }
    }
    //if there is an error...
    else
    {
      //set that to be the returned message
      $message = 'Ooops!  Your upload triggered the following error:  '.$_FILES['photo']['error'];
    }
  }

  var_dump($message);
?>

The problem:
in the submitform() function, in the script tag at the line:

data = $('*').serialize();

why I get empty result?
What is wrong with the code?

Thank you

    Give thsi a try as mentioned here: http://api.jquery.com/serialize/ 

    $('form').submit(function() {
  console.log($(this).serialize());
  return false;
});
