Next on the list is the contact.module. In this one you probably know the basic hooks. So let me break down it by hooks
contact.module
hook help - Provide online user help.
<?php
// $Id: nvr.module,v 1.297.2.4 2009/02/25 12:21:53 traxbarn Exp $
function contact_help($path, $arg){
switch ($path) {
case 'admin/help#contact':
return t('Place your instruction here.');
}
}
hook init - Perform setup tasks. See also, hook_boot.
function contact_init(){
drupal_add_css(drupal_get_path('module','contact') .'/contact.css', 'module');
drupal_add_js(drupal_get_path('module','contact') .'/contact.js', 'module');
}
hook perm - Define user permissions.
function contact_perm(){
return array('view contact');
}
hook access - Control access to a node.
function contact_access($op, $node) {
if (user_access('view contact')) {
return TRUE;
}
}
hook theme - Register a module (or theme's) theme implementations.
function contact_theme(){
return array(
'contact_block' => array(
'arguments' => array('form' => NULL),
'template' => 'contact-block',
),
);
}
hook_block - allows you to specify any custom configuration settings, and how to display the block.
function contact_block($op = 'list', $delta = 0) {
if ($op == 'list') {
$blocks[0]['info'] = t('nvr contact');
$blocks[0]['cache'] = BLOCK_NO_CACHE;
return $blocks;
}
else if($op == 'view' && $delta == 0 && user_access('view contact')){
$block['content'] = theme('contact_block', NULL);
return $block;
}
}
hook menu - Define menu items and page callbacks.
function contact_menu(){
$items['contact'] = array(
'page callback' => 'contact_form_validate',
'access arguments' => array('view contact'),
'type' => MENU_CALLBACK,
);
return $items;
}
hook_form - Display a node editing form.
function contact_form(&$form_state){
$form['name'] = array(
'#title' => 'Name',
'#type' => 'textfield',
'#attributes' => array('style' => 'height:22px;margin-left:6px;width:194px;'),

'#attributes' => array('style' => 'margin:5px 0px 0px 0px; width:315px; cursor: text;'),
'#maxlength' => 200,
'#required' => TRUE,
);
$form['join_list']['join'] = array(
'#type' => 'radios',
'#title' => t('Join our Mailing List'),
'#size' => 20,
'#default_value' => variable_get('join', 1),
'#options' => array(t('Yes'), t('No')),
'#required' => TRUE
);
$form['submit'] = array(

function contact_form_validate(){
$form_state = array('storage' => NULL, 'submitted' => FALSE);
$form_build_id = $_POST['form_build_id'];
$form = form_get_cache($form_build_id, $form_state);

form_set_error('subject', t('Subject field is Required.'));
}
if(empty($form_state['message'])){
form_set_error('message', t('Message field is Required.'));

drupal_set_message(t('Message sent. You have successfully joined our mailing list.'));
}else{
