[Drupal] My method of using ajax in Drupal

That is just my method to create the ajax module. Here I will build a module "myajax" and locate it in sites/all/modules/

1. Create the .info file, insert the content as below.

;$Id$
name = My Ajax Module
description = This is a module which is used when you can do with ajax in the server.
core = 6.x
version = "6.x-1.7"

2. Create the .module file, inster the code as below.

<?php
/**
 * @file
 * My Ajax Module
 *
 * This is a module which is used when you can do with ajax in the server.
 *
 */
function myajax_menu() {
  $items = array();

  $items['insertsth'] = array(
    'page callback'=>'myajax_insertsth',
    'access callback'=>TRUE,
    'type'=>MENU_CALLBACK,
  );
  return $items;
 
}

function myajax_insertsth () {
  //In this function, you can handle with the parameters sent from the client.

  //Use $_GET
  var_dump($_GET);

  //use $_POST
  var_dump($_POST);

 
  //REMEMBER that after you handing with the data, use the die() to stop to load the whole page.
  die();
  //echo "Hello, world!";die();
}

3. Test now!
Now you can insert a test url, such as http://www.example.com/myajax/111, then you can see the result.
Of course, you can create a form, and post the data to the url.

If you have any good idea about how to use ajax in Drupal, please tell me!  :)
