The Quest for a Thank You Message from Drupal's Webform Module

There is a way to send out a thank you message using the advanced php processing that drupal forms currently has:

$to = $form['submitted']['email']['#value'];
$from = variable_get('site_mail', '');
$body = drupal_html_to_text($node->webform['confirmation']);
$message = drupal_mail('webform_extra', 'reply', $to, language_default(), array('body' => $body), $from, TRUE);

function webform_extra_mail($key, &$message, $params) {
$message['subject'] = "Thanks for your interest.";
$message['body'] = $params['body'];

This is all well and good - however it is not very user friendly - here is what I propose:

Add an Auto-responder or Thank you Message in the Web-mail settings.
We need to collect the following data:

• The field that will be used when sending the thank you message
• The email Subject
• The email Body

We will also need the remaining fields to be tokenized as well as having the other site information available.

All I want to accomplish here is when a user fills out a form they receive a thank you message

My approach is to build a custom module called 'webform_autoresponder'

____________________________________________________
My info file:

webform_autoresponder.info
***********************************************************************
; $Id: $
name = Webform AutoResonder
description = Enables Webforms to have a configurable Email Autoresponder field
core = 6.x

Right now I my schema will look something like this

____________________________________
NID / From / Subject / Message /
____________________________________

For the module itself I am using hook form alter to insert my fields where I would like them in the already existing webform edit form:

/**
* Implementation of hook_form_alter().
* Change the way an existing form is rendered
*/
function webform_autoresponder_form_webform_node_form_alter(&$form, &$form_state){
 $form['webform']['mail_settings']['ar_from'] = array(
   '#type' => 'textfield',
   '#title' => t('From'),
   '#description' => t('If you create a conditional email recipient based off a field this is the address that it will be emailed from'),
   '#default_value' => 'confemail',
 );
$form['webform']['mail_settings']['ar_subject'] = array(
   '#type' => 'textfield',
   '#title' => t('Subject'),
   '#description' => t('If you create a conditional email recipient based off a field this is the subject that will be in the email to them'),
 );
 $form['webform']['mail_settings']['ar_confemail'] = array(
   '#type' => 'textarea',
   '#title' => t('Confirmation Email message'),
   '#description' => t('If you create a conditional email recipient based off a field this is the body that will be emailed to them'),
   '#default_value' => 'confemail',
   '#cols' => 40,
   '#rows' => 10,
 );
}

Naturally as this module becomes more mature I will post more code and eventually commit it to the Drupal repository. Please leave any advise or suggestions
