Read this article to learn how we can use various ORM commands in your Web sites without the need to use command line tools.
The article presents a sample project that you can use as a starting point for your own PHP projects.

Getting Started
Converting to use CodeIgniter with HMVC Pattern using Modular Extensions
Conclusion
Getting Started
In this tutorial we will combine the following packages together:
2. CodeIgniter Modular Extensions
You need to download this ORM package.
Start by downloading CodeIgniter 2.2.0. Extract it into your web server's www folder. Browse to /index.php/welcome. You should see CodeIgniter Welcome Page.
CI Configuration
1. Open /application/config/config.php in a editor of your choice.
2. Remove index.php from Line #29. After editing the line should look like as follows:
$config['index_page'] = '';
3. At line #227 of config file set a random encryption key.
4. At line #344 of config file change rewrite_short_tags from FALSE to TRUE. After editing the line should look like as follows:
$config['rewrite_short_tags'] = TRUE;
5. Save & Close the file.
6. Create a new file under your project's root folder named .htaccess and write the following into this file:
php_flag display_errors off AddType text/x-component .htc <IfModule mod_rewrite.c> DirectoryIndex index.php RewriteEngine On RewriteCond $1 !^(index\.php|assets|robots\.txt|favicon\.ico) RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [L] </IfModule> <IfModule !mod_rewrite.c> ErrorDocument 404 /index.php </IfModule> # BEGIN REQUIRED FOR WEBFONTS AddType font/ttf .ttf AddType font/eot .eot AddType font/otf .otf AddType font/woff .woff <FilesMatch "\.(ttf|otf|eot|woff)$"> <IfModule mod_headers.c> Header set Access-Control-Allow-Origin "*" </IfModule> </FilesMatch> # END REQUIRED FOR WEBFONTS
7. Browse to /welcome and now you should see CI Welcome page.
Converting to use CodeIgniter with HMVC Pattern using Modular Extensions
HMVC makes the CodeIgniter PHP framework modular. Modules are groups of independent components, typically model, controller and view, arranged in an application modules sub-directory that can be dropped into other CodeIgniter applications.
HMVC stands for Hierarchical Model View Controller. Module controllers can be used as normal controllers or HMVC controllers and they can be used as widgets to help you build view partials.
Installation:
1. Download and extract CI Modular Extensions from the link above.
2. Drop Modular Extensions third_party files into your application/third_party directory
3. Drop Modular Extensions core files into application/core.
4. Access the URL /welcome => shows Welcome to CodeIgniter
5. Create module directory structure application/modules/welcome/controllers
6. Move controller application/controllers/welcome.php to application/modules/welcome/controllers/welcome.php
7. Access the URL /welcome => shows Welcome to CodeIgniter
8. Create directory application/modules/welcome/views
9. Move view application/views/welcome_message.php to application/modules/welcome/views/welcome_message.php
10. Access the URL /welcome => shows Welcome to CodeIgniter
If you see welcome page correctly then you successfully installed HMVC Pattern into CI.
Installing Smarty
Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. This implies that PHP code is application logic, and is separated from the presentation.
Under the hood, Smarty compiles copies of the templates as PHP scripts. This way you get the benefits of both template tag syntax and the speed of PHP.
Compilation happens once when each template is first invoked, and then the compiled versions are used from that point forward. Smarty takes care of this for you, so the template designer just edits the Smarty templates and never has to manage the compiled versions.
This approach keeps the templates easy to maintain, and yet keeps execution times extremely fast. Since the compiled versions are PHP, op-code accelerators such as APC or ZendCache continue to work on the compiled scripts.
Installation:
1. Download and extract Smarty from the above link.
2. Create smarty directory structure /application/third_party/Smarty
3. Copy files from libs folder of the extracted folder to /application/third_party/Smarty folder.
4. Create directory structure /application/cache/smarty/cache
5. Create directory structure /application/cache/smarty/compiled
6. Make sure above folders both have write access.
7. Create and open a file in /application/core/MY_Output.php and fill it with the following content:
<?php (defined('BASEPATH')) OR exit('No direct script access allowed');
/**
* Turn Smarty debug compatible whith Ci-Smarty parse fetch method
*
* Responsible for sending debug Smarty final output to browser (Smarty_Internal_Debug::display_debug)

class MY_Output extends CI_Output
{
/**
* _display
*
* Turn Smarty debug compatible whith Ci-Smarty parse fetch method
*
* @param string $output output of the method
*
* @return void
*/
function _display($output = '')
{
parent::_display($output);
//If Smarty is active - NOTE: $this->output->enable_profiler(TRUE) active Smarty debug to simplify
if (class_exists('CI_Controller')
&& class_exists('Smarty_Internal_Debug')

4. Create the following folder structures:
/application/models/doctrine/entities
/application/cache/doctrine/generated_entities (give write permission)
/application/cache/doctrine/proxies (give write permission)
5. Open the /application/config/autoload.php file and modify it as follows:
$autoload['libraries'] = array('smarty', 'parser', 'doctrine');
6. Create a file in /application/core/MY_Controller.php and fill it with the following:
<?php (defined('BASEPATH')) OR exit('No direct script access allowed');
/**
* MY_Controller
*
* @category MY_Controller
* @package CodeIgniter
* @author Tariqul Islam <tareq@webkutir.net>
* @license http://directory.fsf.org/wiki/License:ReciprocalPLv1.3 Reciprocal Public License v1.3

* Constructor of MY Controller
*/
function __construct()
{
parent::__construct();
$this->em=$this->doctrine->em;
$this->smarty->assign('currenturl', $this->uri->uri_string());
}
}
7. From now on all of your controllers in all modules should extend MY_Controller.
8. Access the URL /welcome => shows Welcome to CodeIgniter
9. Now we need to define Doctrine Models. We will build our Doctrine Models using AnnotationDriver which is very simple to use.
10. Create /application/models/doctrine/entities/User.php file with following:
<?php

*

13. Now its time to create the database schema, update database schema, drop database schema, etc. To use these commands from web browser, we will now write a module in CI.
14. Create a database in your database server and configure CI accordingly by editing the /application/config/database.php file.
15. Download this module and extract it. Copy orm folder in /application/modules folder.
16. Copy assets folder in /assets folder.
17. Copy generic_helper.php in /application/helpers folder.
18. Access the URL /orm => will show 7 Buttons.
19. Click on Create Schema button. When it shows success then check your database in your database server and you will see that you now have two tables in it named user and user_type.
20. Now its time to populate some default data in our DB. Click Load Fixture Button and check your database tables. Cool. :)
Note: Don't forget to remove orm module in production server. It will be harmful there.
