Add extra fields to the search form

Hi larowlan ,
The second point is not clear :"2) Create this (change YOURMODULENAME to the module's machine name)"

After creating ""this"" what should be done- ? In which file should be put on and what name?

A lot of thanks

Hi larowlan ,
Please help I'm in trouble.I followed step by step all the points but nothing.
A sleepless night and nothing .Please show me step by step with precisions.

for the first point:
1-Create a module (you can use module_builder if you're not sure how to do this).
i use builder but i cannot use it with perfection (please show me how to do it)

2-Create this (change YOURMODULENAME to the module's machine name)

function YOURMODULENAME_form_hotel_booking_search_form_alter(&$form, $form_state) {
  $form['search']['destination'] = array(
    // YOUR FIELD SPEC GOES HERE - SEE <a href="http://api.drupal.org/api/drupal/developer--topics--forms_api_reference.html/6" title="http://api.drupal.org/api/drupal/developer--topics--forms_api_reference.html/6" rel="nofollow">http://api.drupal.org/api/drupal/developer--topics--forms_api_reference....</a> for help
  );
  if (isset($form['results'])) {
     // EDIT THE RESULTS HERE - destination field value is in $form_state['values']['destination']
  }
}

I'm lost in the middle of drupal.

Hi larowlan
This is what I've done so far:

1. i go to /admin/build/module_builder Module builder

Machine-readable name : * i called it "destination"

Nom : * I called it "destination"

Description : * described it like this "Add extra fields to the search form"

Use the following specific hooks : I use ubercart hooks
i select all options :action_info #action_info_alter etc...
in the end i generate the module
I obtain this code for destination.module code :

<?php
// $Id$

/**
* @file
* TODO: Enter file description here.
*/

/**
* Implementation of hook_help().

* by $section to further explain how they work. Adding certain "keywords" to the end of
* a given path (like admin/modules#description) will cause this text to display elsewhere
* in the page as well (in this case, in the description section for the given module).
*/
switch ($path) {

And this for Module info :

; $Id$
name = destination
description = Add extra fields to the search form
core = 6.x

2. I copy and paste the following text into a file called destination.module and destination.info
3. I create a file called destination at sites/all/modules and insert the 2 files (destination.module and destination.info)
4 I go to /admin/build/modules and i enable destination module

after this i go to admin/store/settings/store i obtain this error:
Fatal error: Unsupported operand types in /var/www/clients/client0/web94/web/sites/all/modules/ubercart/uc_store/includes/uc_price.inc on line 181

Thanks for all
