How to Add a Field to the Drupal Contact form

Ever wish you could use the existing Drupal Contact module as your sitewide contact form and just add a field or two? You can and it's really easy. All you need to do is create a new module and add the fields via the hook_form_alter() function. Here's an example of how we do it on

 * Implementation of hook_form_alter().
 * @see
 * We add a few custom fields to the default Drupal contact form
function mtmcontact_form_contact_mail_page_alter(&$form, $form_state) {
	$form['company'] = array(
		'#title' => t('Your company'),
		'#type' => 'textfield',
		'#required' => true,
	$form['phone'] = array(
		'#title' => t('Your phone'),
		'#type' => 'textfield',
	// reorder the elements in the form to include the elements being inserted
	$order = array('contact_information', 'name', 'company', 'phone', 'mail', 'subject', 'message', 'copy', 'submit');
	foreach($order as $key => $field) {
		$form[$field]['#weight'] = $key;

The second part keeps the fields in an explicit order and includes references to the form elements that are already created by the Contact module. To change the order, simply modify the array.

Where in drupal, i mean in which file I have to do this changes. I am using drupal version 6. So please help me out.

Sorry for not putting home page, because i have my site on localhost. Trying to learn drupal.


Someone knows how to add a javascript function (es. onchange) to a the SELECT tag of Category filed in Drupal 6?

I'm trying with #attributes but seems not work..

WHat D version is this for? I'm just trying to add a "phone" field in D7 (first project since moveing from D6) and it won't work using hook_form_alter!

Since this article is for drupal 6, how do I add another field in drupal 7?

it works well to add field for this form .but how can i save the field's data to database ?

FYI, in drupal 7 the hook changes, you need to use:


So your function would look like:

function yourmodule_form_contact_site_form_alter(&$form, &$form_state, $form_id) {
// place code here.

Use something like this to send company and phone with mail message:

* Implements hook_mail().
function YOURMODULENAME_mail_alter(&$message) {
if ($message['id'] == 'contact_page_mail' ||
$message['id'] == 'contact_page_autoreply') {
$message['body'][] = t('company') . ': "' . $message['params']['company'] . '"';
$message['body'][] = t('phone') . ': "' . $message['params']['phone'] . '"';

. . .

I am using CCK email field that redirect to drupal default contact form. In that case the form changed from contact_page_mail to something different. How to find the form ID. I have just changed the code mentioned for default contact form to CCK email filed contact. everything is working fine but the information which is filled in the new fields is not sent on email. I am not able to get the exact form ID.

Can you tell me how find the form ID?
