CodeIgniter: global variables in a controller

What you can do is make "class variables" that can be accessed from any method in the controller. In the constructor, you set these values.

class Basic extends Controller {    // "global" items    var $data;    function __construct(){        parent::__construct(); // needed when adding a constructor to a controller        $this->data = array(            'title' => 'Page Title',            'robots' => 'noindex,nofollow',            'css' => $this->config->item('css')        );        // $this->data can be accessed from anywhere in the controller.    }        function index(){        $data = $this->data;        $data['my_data'] = 'Some chunk of text';        $this->load->view('basic_view', $data);    }    function form(){        $data = $this->data;        $data['my_other_data'] = 'Another chunk of text';        $this->load->view('form_view', $data);    }}

You can setup a class property named data and then set it's default values into the contructor which is the first thing which is run when a new instance on Basic is created.Then you can reference to it with the $this keyword

class Basic extends Controller{   var $data = array();   public function __construct()   {       parent::__construct();       // load config file if not autoloaded       $this->data['title'] = 'Page Title';       $this->data['robots'] = 'noindex,nofollow';       $this->data['css'] = $this->config->item('css');   }   function index()   {       $this->data['my_data'] = 'Some chunk of text';       $this->load->view('basic_view', $this->data);   }   function form()   {       $this->data['my_data'] = 'Another chunk of text';       $this->load->view('form_view', $this->data);   }}

hey thanks here's my snipetit's a global variable holding a view

/* Location: ./application/core/MY_Controller  */class MY_Controller extends CI_Controller {    function __construct()    {        parent::__construct();        $this->data = array(            'sidebar' => $this->load->view('sidebar', '' , TRUE),        );    }}/* Location: ./application/controllers/start.php */class Start extends MY_Controller {    function __construct()    {               parent::__construct();    }    public function index()    {        $data = $this->data;        $this->load->view('header');        $this->load->view('start', $data);        $this->load->view('footer');    }}
