I'm back,

after long research, and almost switch to joomla, i decided to write website in ci.

Question how to

Code:

<?php

class Welcome extends Controller {

    function Welcome()
    {
         parent::Controller();
    }
    
     function index()
    {
        $data['title']  = 'Tytul mojej strony';
        $data['menu']  = '<a href="http://intype.info/">Link 1</a>
<a href="http://intype.info/">link 2</a>';
        $data['content']  = '<h2>Lorem ipsum</h2>Lorem ipsum dolor sit amet.';
        $data['sidebar']  = '<a href="http://intype.info/" title="Intype" target="_blank">link</a><br /><a href="http://intype.info/" title="Intype" target="_blank">link</a>';
        $data['footer']  = 'Copyright 2010 by Me :)';
        $this->parser->parse('page', $data);  
    }
    function about()
    {
    
    $this->parser->parse('page', $data);  
    
    }
}

how to pass $data form controller/index to controller/about ?
(In future values will be taken form DB)
Is it a good way to build website?
