Changing the default controller naming convention in CodeIgniter

CodeIgniter is one of my favorite framework and I often use it for developing application quickly. Although it is very flexible in most cases, I find its naming convention to be strict. Many times I have faced this problem when my controller’s class name and a model/library’s class names are the same – a Fatal error is inevitable and I have to forcefully change the name of the conflicting class to something less desirable (say from Users to UsersModel). Today I wanted to end this problem.

So I extended the CI_Router core class and made change to the _validate_request method. Now I can name my controller classes in this fashion: UsersController and it resides on the file system as controllers/UsersController.php. If you’ve tried other established frameworks, you should notice that this naming convention is widely used. So, if you have the same need, then just download the MY_Router.php file and put it on your application/libraries folder. That’s it.

Here is how your controller would start:

[cc lang=’php’]

Code Updates (HTTP class, Extended CodeIgniter Model, Cross-domain AJAX transport)

Greetings to all the readers of my blog.

Many of you have been writing to me in the last couple days when I took the site down. The main objective was to add the new theme and push a few code updates of the existing libraries. I really appreciate your concern and would like to reassure you that the site is up and will be up as usual ๐Ÿ™‚ Now, besides the slightly customized theme from Elegant Themes, I have put a few code updates. They are detailed below:

Extended Model for CodeIgniter

The original version of the Extended Model for CodeIgniter has been serving many people well. Although most users loved the nifty functions of the Model, many (including me) didn’t like the hacking of CI core to get this functionality. With the release of CodeIgniter 1.7, we can avoid that as we can now overload the Model class of CI like the other libraries. Follow this instruction:

1. Download the updated version from here
2. Put it in your application/libraries folder
3. In your model files, use it this way: class Product extends MY_Model
4. Everything else is same just like the original one

HTTP Class

There is not much update in this class except for a few bug fixes (thanks to you guys). Also, I have included a license file in the package as many of you have asked. It’s released under the MIT license. The original post is here for reference.

Download the update from here and the API reference is here.

Cross-domain AJAX calls using PHP

A minor bug fix in the code. Thanks to a few of you who pointed them out. Original post is here. Download the update from here.

I have accelerated plans for the blog in 2009 so stay tuned for some worthy posts in this month. And do write to me if you feel you have any questions/ideas/suggestions.


Extended Model for CodeIgniter

Feb 2009: An updated version of the code for CodeIgniter 1.7.x can be found here.

I developed this extension of CodeIgniter’s Model last year, but never had the chance to publish it. The main purpose of this extension is to make a dev’s life easy. This extension has been used by several of my devs at RBS and has been proved to increase productivity and reduce the number of painful small queries to write. Their enthusiasm has driven me to post this for the CI fans out there.

Without much babble, let’s get into point. I’ve explained the process of installing it and then showed some example uses. For starter, click here to download it. Now follow these steps to get started:


Htpasswd protection library for Code Igniter

This is a library designed to run with Code Igniter that allows the application to protect any folder in the webserver using the htpasswd method of Apache. It can also group the users and create group based permission on the folders. The use is very simple: you need to define an array of the users (and array of groups if you need that), tell it where to store the password files and tell which folder to protect. It will do the rest for you. Here goes the function:

     * Protect a given folder with htpasswd protection method
     * @author  Md Emran Hasan <>
     * @param   string  location of the folder to protect
     * @param   string  location of the folder to write the group and password file
     * @param   array   an array with the users info (username and password)
     * @param   array   an array with the groups along with their user list
     * @return  boolean
     * @access  public
    function protect($protectFolder, $passFolder, $userData, $groupData = array())

It is a small part of the large protection library I have been developing for a membership management application called MemberSmart . This application allows someone to protect their PHP and non-PHP based files residing in a server in a number of ways. Among the methods, the htpasswd is the most easy and convenient one. This application will be released soon by the client I am working for.

Download the library with the example from Here is an example controller highlighting the use of the library.


class Protect extends Controller {

    function Protect()
    function index()
        // Load the library
        // Create the user array (this might come from your db)
        $userData = array(
                                    ‘username’ => ‘admin’,
                                    ‘password’ => ‘root’
                                    ‘username’ => ‘test’,
                                    ‘password’ => ‘test123’
                                    ‘username’ => ’emran’,
                                    ‘password’ => ‘hasan’

        // Create the group array (this might also come from your db)
        $groupData = array(
                                    ‘name’ => ‘ADMIN’,
                                    ‘users’ => array(‘admin’, ’emran’)
                                    ‘name’ => ‘QA’,
                                    ‘users’ => array(‘test’)

        // Define the root to the folders

        // Protect them!
        $action = $this->authhtpasswd->protect($rootDir . ‘cs’,
                                         $rootDir . ‘data’,

        // Is there any error? If yes, then show them!
        if (!$action)
