This document provides instructions for installing and configuring the CodeIgniter PHP framework. It describes downloading CodeIgniter, creating controllers and views to route requests and display content, and configuring routes to map URLs to controllers and views. It also explains how to remove "index.php" from URLs using an .htaccess file for cleaner URLs.

1. CodeIgniter Framework
Intro

2. Instalarea CodeIgniter
• Descarcati un schelet de aplicatie CodeIgniter de
aici:
https://www.codeigniter.com/
Dezarhivati-o si copiati-o in directorul proiectului
vostru din htdocs.

3. Executati proiectul
si veti obtine:

4. • Observati ca in In Source Files->application-
>controllers avem controllerele Welcome si
index. Stergeti-le.
• Vom defini controllerele WelcomeController si
HomeController
In Source Files->application->controllers creati
fisierele:
WelcomeController.php si HomeController.php

6. • Editati WelcomeController.php astfel:
<?php
class WelcomeController extends CI_Controller {
public function index()
{
echo "Welcome to my first controller";
}
}
Accesati adresa:
localhost/CIgniter1/index.php/WelcomeController
pentru a apela metoda index a controller-ului
WelcomeController

7. • Pentru ca WelcomeController sa fie apelat
implicit la adresa localhost/CIgniter1/index.php
vom edita fisierul application/config/routes.php
$route['default_controller'] = 'WelcomeController';
Acum accesati localhost/CIgniter1/index.php si
observati ca a este apelata metoda index a
controller-ului WelcomeController

8. • In controller-ul WelcomeController adaugati metoda first_view
care va apela vederea welcome_view.php
• Editati WelcomeController astfel:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class WelcomeController extends CI_Controller {
public function index()
{
echo "Welcome to my first controller";
}
public function first_view(){
$this->load->view('welcome_view');
}
}
Astfel va fi apelata vederea: /application/views/welcome_view.php

9. Vederea welcome_view
• Creati fisierul
/application/views/welcome_view.php
si editati-l astfel:
<?php
echo "This my first view!";
Apelati adresa:
http://localhost/CIgniter1/index.php/WelcomeC
ontroller/first_view si obs ca astfel se va apela
vederea welcome_view

10. • Pentrua apela vederea welcome_view la tastarea
adresei:
• http://localhost/CIgniter1/index.php/welcome
editati application/config/routes.php astfel:
$route['default_controller'] = 'WelcomeController';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
$route['welcome'] =
'WelcomeController/first_view';

12. HomeController
• Editati HomeController.php astfel:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class HomeController extends CI_Controller {
public function index()
{
echo "Welcome to my home controller";
}
}
Accesati adresa:
localhost/CIgniter1/index.php/HomeController pentru a apela
metoda index a controller-ului HomeController

13. • Pentru a putea accesa pagina la adresa:
localhost/CIgniter1/index.php/home
editati fisierul de routare astfel:
$route[‘home’] = ‘HomeController/index';

14. • In controller-ul HomeController adaugati metoda home_view care
va apela vederea my_home_view.php
• Editati HomeController astfel:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class HomeController extends CI_Controller {
public function index()
{
echo "Welcome to my home controller";
}
public function home_view(){
$this->load->view('my_home_view');
}
}
Astfel va fi apelata vederea: /application/views/my_home_view.php

15. Vederea my_home_view
• Creati fisierul
/application/views/my_home_view.php
si editati-l astfel:
<?php
echo "This is my home view!";
Apelati adresa:
http://localhost/CIgniter1/index.php/HomeCont
roller/home_view si obs ca astfel se va apela
vederea my_home_view

16. • Pentrua apela vederea welcome_view la tastarea
adresei:
• http://localhost/CIgniter1/index.php/home/view
editati application/config/routes.php astfel:
$route['default_controller'] = 'WelcomeController';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
$route['welcome'] =
'WelcomeController/first_view';
$route['home'] = 'HomeController/index';
$route['home/view'] =
'HomeController/home_view';

18. Eliminarea index.php din adresa!
• Pentru ca in loc de
http://localhost/CIgniter1/index.php/home/view
sa putem apela
http://localhost/CIgniter1/home/view
vom face urmatoarele modificari:
1. Copiati fisierul .htaccess din directorul
applications in directorul root

20. 2. Editati fisierul .htaccess astfel:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /CIgniter1/
RewriteCond %(REQUEST_FILENAME) !-f
RewriteCond %(REQUEST_FILENAME) !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
