At least now I do not need to creating custom module to get this simple feature.

Reform: sometimes we want something simple, such as setting up the minimum length and maximum length of a username. drupal.org/project/reform — Danang Probo Sayekti (@danpros) July 25, 2012

Creating custom user registration form sometimes can be a little tricky, but lets try to create a custom registration form in Drupal 7 with just a few steps.

First we add a few lines of codes to template.php as follows

function themename_theme($existing, $type, $theme, $path){
  $hooks['user_register_form']=array(
    'render element'=>'form',
    'template' =>'templates/user-register',
  );
return $hooks;
}

function themename_preprocess_user_register(&$variables) {
  $variables['form'] = drupal_build_form('user_register_form', user_register_form(array()));
}

Then creating the user-register.tpl.php and place it inside templates folder in your theme, write the following in your user-register.tpl.php:

<?php 
  print render($form['form_id']);
  print render($form['form_build_id']);
  print render($form['account']['name']);
  print render($form['account']['mail']);
  print render($form['field_yourcustomfield']); // Your Drupal 7 profile field if any.
  print drupal_render($form['actions']); 
?>

Clear your Drupal cache and visit your user registration form to see the changes.

Some time ago I need to creating a Webform where visitors need to fill in the data required before they can download a specific file.

So the order is as follows:

1. Send data to the server such as name, email, company, etc. (site A and site B has different server).
2. Read the string given by the server in the form of JSON. The given string is a place where we can download the file.

Examples of JSON string:

{"success":true,"downloadUrl":"http://www.example.com/webfiles/example.exe"}

As usual, I use Drupal, and using the Webform module.

To be much faster, I just changed the webform-confirmation.tpl.php and named according to the ID of the webform (eg webform-confirmation-1.tpl.php) and put it in the theme folder that is used. Here is the code:

$submission_data = webform_menu_submission_load($sid, $node->nid);
 $url = 'http://www.example.com/download.php?';
 $data = array (
  'manager' => $submission_data->data[1]['value'][0],
  'email' => $submission_data->data[2]['value'][0],
  'company' => $submission_data->data[3]['value'][0],
  'country' => $submission_data->data[4]['value'][0],
  'model' => $submission_data->data[5]['value'][0],
  'feature' => $submission_data->data[6]['value'][0],
  'srlnbr' => $submission_data->data[7]['value'][0],
  'prodid' => $submission_data->data[8]['value'][0]
 );
 $query = http_build_query($data, '', '&');
 $f_url = $url . $query;
 $content = file_get_contents($f_url);
 $json = json_decode($content);
 $dl = $json->{'downloadUrl'};
 if ($dl == '') {
  // null
 }
 else {
  header('Refresh: 3; URL=' . $dl);
 }

With the solution above, we do not need to use JavaScript / jQuery. We could also use drupal_http_request(); but more effective using above methods because I need to read the JSON string also.
