Introduction
Overview § A fast, flexible, lightweight, concise, mature and fully documented MVC framework § Excellent backward compatibility § Distributed as open source (pseudo-BSD) § Majority of modules are BSD/GPL § Fixed release cycles § Backed by an active community § Needs a webserver (Apache, IIS, NGINX, …), PHP 5.1.6+, optionally a DB
Internals §
MVC with singleton loader
§
Config, Loader, Router, Cache, Helper, Driver, URI, Hook & Class modules
§
Extend via MY_, Libraries (incl. external), Helpers
§
Super object ( &get_instance() )
§
No strict rule enforcement
Basics §
Segment based URLs www.site.com/class/function/param/param www.site.com/index.php/controller/function/param
§
Controllers $this->load->model(‘customers’); $this->load->view(‘header’); $this->load->helper(‘url’’); If (! $this->auth->logged_in() ) … redirect(‘url’,’refresh)’;
Input §
Post, (GET) $this->input->post(‘name’);
§
Form Validation $this->form_validation->set_rules(‘name’,’Name, ‘required’, myfunc); if ( $this->form_validation->run() == FALSE) … $this->load->view(‘error’);
Processing §
Models(DB w/ ActiveRecord) $this->load->database(); $query = $this->db->select(‘name’) ->from(‘users’) ->where(‘id’,1) ->limit(1) ->get();
return $query->row(); return $query->row_array();
Rendering §
Output $data['page_title'] = 'Your title'; $this->load->view('header’, $data); $this->load->view('menu'); $this->load->view(’page’); $this->load->view('footer'); $this->output->set_header("HTTP/1.0 200 OK");
