Overview CI framwork CodeIgniter URLs URI Routing Controllers Models Views Auto-loading Resources Security Managing your Applications

CodeIgniter URLs segment-based example.com/ class / function / ID query string example.com/index.php?c=controller&m=method Adding a URL Suffix example.com/index.php/products/view/shoes.html

URI Routing Wildcards $route['product/:num'] = "catalog/product_lookup"; Regular Expressions $route['products/([a-z]+)/(\d+)'] = "$1/id_$2";

Controllers class News extends Controller { function News() { parent::Controller(); } function index() { $data['tpl_view'] = 'news/index'; $data['active_tab'] = 'news'; $this->load->view('layout',$data); } Function otherFunction($para1, $para2){ // process data and set view here } }

Models class NewsDAO extends Model { function NewsDAO () { parent::Model(); } function verifyUser($username,$password){ $this->db->select('id,username'); $this->db->from('admin'); $this->db->where('username', $username); $this->db->where('password', $password); $this->db->where('active', 'Yes'); $this->db->limit(1); $Q = $this->db->get(); return $Q; } Function otherFunction($para1, $para2){ // process data} }

Views <?php $this- >load->view('header'); ?>  <?php $this- >load->view ($tpl_view ); ?>  <?php $this- >load->view('footer'); ?>

Auto-loading Resources libraries, helpers, and plugins to be initialized automatically every time the system runs. $autoload['libraries'] = array('database', 'session', 'validation'); $autoload['helper'] = array('url');
