CodeIgniter: global variables in a controller

Question

I'm a very newbie on CodeIgniter, and while I go on I run into problems that, in the procedural coding, were easy to fix

The current issue is: I have this controller

class Basic extends Controller {      function index(){         $data['title'] = 'Page Title';         $data['robots'] = 'noindex,nofollow';         $data['css'] = $this->config->item('css');         $data['my_data'] = 'Some chunk of text';         $this->load->view('basic_view', $data);     }      function form(){         $data['title'] = 'Page Title';         $data['robots'] = 'noindex,nofollow';         $data['css'] = $this->config->item('css');         $data['my_other_data'] = 'Another chunk of text';         $this->load->view('form_view', $data);     } } 

As you can see, some array items repeat over and over:

$data['title'] = 'Page Title'; $data['robots'] = 'noindex,nofollow'; $data['css'] = $this->config->item('css'); 

Isn't there a way to make them "global" in the controller, so that I have not to type them for each function? Something like (but this gives me error):

class Basic extends Controller {      // "global" items in the $data array     $data['title'] = 'Page Title';     $data['robots'] = 'noindex,nofollow';     $data['css'] = $this->config->item('css');      function index(){         $data['my_data'] = 'Some chunk of text';         $this->load->view('basic_view', $data);     }      function form(){         $data['my_other_data'] = 'Another chunk of text';         $this->load->view('form_view', $data);     }  } 

Thnaks in advance!

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);     }  }
