CodeIgniter and Ajax Using JQuery Tutorial

This post is outdated, and might and might not work. Unfortunately I currently don’t have time to check and/or fix it. Sorry 😦

I created this tutorial because I was having a hard time finding good simple CodeIgniter + JQuery tutorial for newbie like me. The one I found, created by MR Forbes, is hard to understand and apparently isn’t working. Another one, pr0digy’s, is using Mootools for the AJAX framework.

So I decided to create my own CodeIgniter and JQuery tutorial based on pr0digy’s tutorial. I’m assuming you already know how to code using CodeIgniter. If you’re new to CodeIgniter, you need to find others tutorial first. The videos given in CodeIgniter’s site is a good start.

This tutorial is about creating simple CodeIgniter + database + ajax system. User will be shown a form to post a message. Then after he/she press the submit button, the system will save the message using ajax and then show the message. You could see the result first if you want.


The first thing we need to do is creating a table to save the message. For this tutorial, We will use this:

  `id` tinyint(4) NOT NULL auto_increment,
  `message` varchar(256) NOT NULL,
  PRIMARY KEY  (`id`)


Then, we need to create a controller. My controller is named message. You could name your controller any name you like. After that, create 2 functions/methods, view and add.

view is used to get the default view and list of messages from the database. The codes are:

function view($type = NULL)
    // get data from database
    $data['messages'] = $this->Message_model->get();

    if ($type == "ajax") // load inline view for call from ajax
        $this->load->view('messages_list', $data);
    else // load the default view
        $this->load->view('default', $data);

We fetch messages from the database using Message_model->get() function. Then the data is passed to the view. Here, we have 2 views called. One for the default view, where we called the page using message/view, and the other is for calling from ajax.

add is a proccess used to insert the message to the database. The codes are:

function add()
    // if HTTP POST is sent, add the data to database
    if($_POST && $_POST['message'] != NULL) {
        $message['message'] = $this->input->xss_clean($_POST['message']);
    } else

This function is accessed when we press the submit button from the form. This function will save the message using Message_model->add() function.


The next thing we need to create is the model. I use Message_model for the name. Here we create two functions, add and get. add is a function to insert the data into the database. get is a function to retrieve data from database. I think the codes are pretty self-explainatory, but you could drop me a message if you need some explainations on the codes.

function add($data)
    $this->db->insert('messages', $data);

function get($limit=5, $offset=0)
    $this->db->orderby('id', 'DESC');
    $this->db->limit($limit, $offset);

    return $this->db->get('messages')->result();


I use 2 files for view section. default.php and message_list.php. The message_list is used for displaying the messages taken from the database.

load->view(‘messages_list’) ?>
  1. message ?>

Hey, Where’s the JQuery?

Here we go. The last, and maybe the most important part of this tutorial. So, we the our controller, we had the model, and we had the views. I assume you already know how to include a jquery script to your view. The jquery codes are this:

$(document).ready(function() {
    $('#submit').click(function() {

        var msg = $('#message').val();

        $.post("", {message: msg}, function() {

So, when we click the submit button, the javascript will take the value of input textbox then send it to message/add using post method. When the action succeed, the script will call message/view/ajax. Note the ajax keyword. It will call the message_list view instead of the default one. Then the view will replace the content in div#content tag.

Well done. You could see the demo I made from the tutorial.

You could download the whole files used in this tutorial in [download#1#size#nohits].

Or, if you prefer to get one by one,

I hope this tutorial helps newbie like me. If you have any question, just drop a comment below 😉

Check Your System Compiz Capability

There is a great script created to check whether your system is compiz ready or not. It’s called Compiz-Check.

Gathering information about your system...

 Distribution:          Ubuntu 8.04
 Desktop environment:   GNOME
 Graphics chip:         nVidia Corporation G70 [GeForce 7300 GT] (rev a1)
 Driver in use:         nvidia
 Rendering method:      Nvidia

Checking if it's possible to run Compiz on your system...

 Checking for texture_from_pixmap...               [ OK ]
 Checking for non power of two support...          [ OK ]
 Checking for composite extension...               [ OK ]
 Checking for FBConfig...                          [ OK ]

Checking for hardware/setup problems...            [ OK ]

If you got [ OK ] in every check, like mine, then your system is ready to run compiz. If something fails, go check the forum 😀

Waiting for The Next Internet Buzz in Indonesia

So, despite the low penetration of internet in Indonesia, apparently its internet “society” is keep growing bigger and bigger. The Web 2.0 era is really expanding here.

It’s started with the large number of blogs created and written by Indonesian few years back. Thanks to blogger like Boy Avianto, Priyadi, Enda Nasution, and some others, people started to create blog to share their stories and knowledges.

Then, following the increasing number of Indonesian bloggers, Indonesian web 2.0 services started to show up. Some are Lintas Berita — a digg-like news site, Sharing Foto — a photo sharing website (too bad it’s closed), kronologger — a microblogging service. A believe there are plenty others I haven’t heard.

And now, we Indonesian have our own free blogging services. Blog Detik and and daddigdug two biggest free blogging services available. Blog Detik has the largest (citation needed) Indonesian news site behind it,, while daddigdug has some great Indonesian blogger working on it.

I believe there is still more to come. Internet offers limitless posibilities. Everyday, I always exited to find out what’s new from Indonesia. I eagerly read every blog I know, and hoping for something new. And talking about new innovation, I have names that I believe will bring new innovations to web 2.0 in Indonesia, some are Akhmad Fathonih and Kukuh TW.

How To Install Oracle XE in Ubuntu 64 Bit

While you’re thinking by installing 64 bit linux you’re standing in the edge of new technology era, it sucks knowing our 64 bit system is less supported than the old 32 bit system. We have to install 32 bit flash since Adobe didn’t have the 64 bit one. We have to install 32 bit oracle xe since Oracle also didn’t have 64 bit version.

And now I will try explain how to install oracle xe into the 64 bit system, ubuntu way. Of course we couldn’t follow the guide from oracle, since apt-get will detect our system architecture and we won’t get the 32 bit packages list.

Before we start, make sure you have the 32 bit library installed. It’s in reposity, all you have to do is

sudo apt-get install libc6-i386

The next thing to do is download the files needed. It’s libaio_0.3.104-1_i386.deb and oracle-xe-universal_10.2.0.1-1.1_i386.deb. You could use wget for this

wget -c

After your downloads are finished, we continue to the main issue, forcing the package to be installed. You could try to install with usual dpkg -i first to make sure your system is really 64 bit.

sudo dpkg -i libaio_0.3.104-1_i386.deb

You’ll get error,

dpkg: error processing libaio_0.3.104-1_i386.deb (--install):
package architecture (i386) does not match system (amd64)
Errors were encountered while processing:

Added guide from Venka A

sudo apt-get install bc

To force the installation, do these

dpkg -i --force-architecture libaio_0.3.104-1_i386.deb
dpkg -i --force-architecture oracle-xe-universal_10.2.0.1-1.1_i386.deb

And after the installation is finished, you need to configure it

sudo /etc/init.d/oracle-xe configure

and edit your ~/.bashrc

export PATH

And, voila, the oracle xe is ready. You could go to from your browser.

Shorcuts for Managing Window(s)

Since I’m not using any window decorator for my gnome setup, I always count on keyboard and mouse combination shortcut for managing my windows. These are my regularly used shortcuts when I’m working.

  • Alt + mouse button 1 (left mouse button): move window. Remember this, and your life would be lot easier. Seriously. I even bring this habbit to MS Windows. You don’t need to move your mouse to title bar and click it there to move the window. Just hold Alt button, and click anywhere inside the window, and you could move it anywhere.
  • Ctrl + Alt + d: show desktop. Easily “minimize” all your opened windows. Very useful when your desktop is cluttered and you want to open new application.
  • Alt + F9: minimize current window.
  • Alt + F8: resize current window. Having no window decorator makes resizing window a little bid harder. But Alt + F8 really helps a lot.
  • Alt + F7: move current window.
  • Alt + F10: maximize current window.
  • Alt + F5: unmaximize current window.
  • Alt + F4: close window. Some application could also use Ctrl + W, Alt + Q.
Tagged , , , 3.0 Beta 3.0 Beta is ready for testing. 3.0 will support the upcoming OpenDocument Format (ODF) 1.2 standard, and is capable of opening files created with MS-Office 2007 or MS-Office 2008 for Mac OS X (.docx, .xlsx, .pptx, etc.). This is in addition to read and write support for the MS-Office binary file formats (.doc, .xls, .ppt, etc.).

See more features in the website, or go try yourself.
