This is a small template class that I am currently using on a university project.
Open config/autoload.php and add template as shown below.
$autoload['libraries'] = array('template');application/libraries/Template.php
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
/**
* Template Class
*
* Template View Parse Class
*
* @package CodeIgniter
* @subpackage Libraries
* @category Templates
* @author Koola
* @link
*/
class Template {
/**
* Constructor
*
* @access public
*/
function __construct()
{
log_message('debug', "Template Class Initialized");
}
// --------------------------------------------------------------------
/**
* Load template
*
* @access public
* @param String
* @param Array
* @param Array
* @param bool
* @return parsed view
*/
function load($template = '', $view = array(), $vars = array(), $return = FALSE)
{
$this->CI =& get_instance();
$tpl = array();
// Check for partials to load
if (count($view) > 0)
{
// Load views into var array
foreach($view as $key => $file)
{
$tpl[$key] = $this->CI->load->view($file, $vars, TRUE);
}
// Merge into vars array
$vars = array_merge($vars, $tpl);
}
// Load master template
return $this->CI->load->view($template, $vars, $return);
}
}

<h1>Small Template Library</h1>
<p>You just called your first template!</p>

<?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);
}
}
?>Calling multiple views is easy:
$partials = array('content'=>'article','head'=>'header','footer'=>'footer');Key in the array above is the PHP var (i.e. <?=$content;?> ) that should match the var in your master template. Value is the filename to call from your views directory.
$this->template->load('main', $partials, $data);Main in the above code is the Master Template file. Partials is view array. Data passes array data just like a view call.
