Simulacija telefonskog imenika _ CodeIgniter

MVC arhitektura

CodeIgniter je baziran na MVC (model – view – controller) strukturi koja pomaže da projekat ostane lepo struktuiran i jasan. To znači da radite po nekom standardu koji omogućava udobnije i brže pravljenje kao i mnogo lakše održavanje. Isto tako je moguće snaći se u kodu koji je neko drugi pisao bez većih poteskoća, kao i brže adaptiranje nekoga ko je ubačen usred projekta. Takođe, omogućava ponovno korišćenje koda, sto znači da ako ste jednom napravili na primer sistem za login, moći ćete da ga koristite uz minimalne izmene i u drugom projektu.

Zašto ga koristiti

• Laka instalacija i konfiguracija 
• Čista i elegantna MVC implementacija
• Nudi i Active Record za upravljanje bazom podataka
• Dobre performanse
• Veliki broj biblioteka i helpera koje olakšavaju rad
• Velika CI zajednica

Instalacija

Da bi ste instalirali CodeIgniter, neophodno je preuzeti poslednju verziju sa zvaničnog sajta i raspakovati je (ukoliko koristite xampp onda je to folder htdocs).

O aplikaciji "Telefonski imenik"

Ovo je tipična CRUD aplikacija koja ima za cilj da demonstrira moj skromni trud. Koristi login system za pristup aplikaciji. Korisnik može biti "admin" i ima mogućnost kompletnog upravljanja (pregled sa dodavanjem/izmenom novih telefonskih korisnika i novih korisnika sistema) ili "user" (samo pregled). U aplikaciji su detaljno razrađene sesije (njihove biblioteke), active record, validacija formi, email class, URI segment i mnoge druge.

Za početak baza

Ova aplikacija koristi MySql bazu podataka imenik.sql

Pristup bazi

Fajl application/config/database.php apdejtovati u sledeće:

$db['default']['hostname'] = 'localhost';
$db['default']['username'] = 'root';
$db['default']['password'] = '';
$db['default']['database'] = 'imenik';

Postaviti default controller

Fajl application/config/routes.php - LoginController predstavlja default controller (automatski se učitava prilikom upisa URL-a).

$route['default_controller'] = "LoginController";  

Učitati potrebne biblioteke i helpere

U fajlu application/config/autoload.php moguće je automatski učitati potrebne biblioteke koje će se učitati u controller-ima kada je to potrebno. Postoji mogućnost i ručnog pozivanja biblioteka koje se učitavaju prilikom izvršavanja skripta (npr. $this->load->library('form_validation'); ), mada ja više volim ovako. 

$autoload['libraries'] = array('database', 'session', 'form_validation', 'email');
$autoload['helper'] = array('url', 'form');    

Podesiti Encryption Key za sesije
Pošto ova aplikacija koristi sesije, neophodno je podesiti encryption key (ključ po kome se sesije kriptuju). U fajlu application/config/config.php postaviti sledeće:

$config['encryption_key'] = 'very_big_number';

Code aplikacije

Ovde je prikazan svaki Controller, Model i View koji aplikacija koristi.
