[h2]Source[/h2]
[h4]Template.php[/h4] [code] <?php if (!defined('BASEPATH')) exit('No direct script access allowed'); /**

[h4]application/views/about.php[/h4] [code]
You just called your first template!
Page rendered in {elapsed_time} seconds
[h4]application/views/main.php[/h4] [code] <html> <head> <title><?=$title;?></title> <style type="text/css"> body { background-color: #fff; margin: 40px; font-family: Lucida Grande, Verdana, Sans-serif; font-size: 14px; color: #4F5155; } h1 { color: #444; background-color: transparent; border-bottom: 1px solid #D0D0D0; font-size: 16px; font-weight: bold; margin: 24px 0 2px 0; padding: 5px 0 6px 0; } </style> </head> <body>
</body> </html> [/code]
[h4]application/controller/home.php[/h4] [code] <?php
class Home extends Controller {
function __construct()
{
parent::Controller();
}
function index()
{
$data['title'] = 'My page title';
$partials = array('content'=>'about');
$this->template->load('main', $partials, $data);
}
} ?> [/code]
[h2]Operation[/h2]
Calling multiple views is easy:
[code] $partials = array('content'=>'article','head'=>'header','footer'=>'footer'); [/code]
Key in the array above is the PHP var (i.e. <?=$content;?> ) that should match the var in your master template. Value is the filename to call from your views directory.
[code] $this->template->load('main', $partials, $data); [/code]
Main in the above code is the Master Template file.
Partials is view array.
Data passes array data just like a view call.
