Before I begin I have to say that I have recently started learning CodeIgniter, so I'm sorry if I repeat this subject once again.
In procedural php I would do something like this
// the header.php
<!DOCTYPE html>
<html>
<head>
<meta name="description" content="blah blah">
<title>My Site</title>
<link href="css/main.css" rel="stylesheet" media="screen">
<php? if($current_page == 'about.php'): ?>
<link href="css/secondary.css" rel="stylesheet" media="screen"> // or some embed styles (<stlye> ... </style>)
<?php endif; ?>
<script src="http://code.jquery.com/jquery.js"></script>
<script src="js/main_script.js"></script>
<php? if($current_page == 'contact.php'): ?>
<script src="js/validation.js"></script>
<?php endif; ?>
</head>
<body>
// end of header.php
include('template/header.php');
<h1>Heading1</h1>
<p>Lorem Ipsum...</p>
include('template/footer.php');
//footer.php
//maybe some js and here
</body>
</html>
So I would like to do something similar and in CI. All pages/views will have the same main styles or scripts, but in some cases, some specific pages (like contact.php) may include, and only in these pages, some specific styles or scripts (like the validation.js).
I have found this video that shows how to create a template/layout library using CI, but I'm not quite sure how I can apply this functionality to work properly.

Put the bottom class in libraries/Layout.php (your app not the sys). In the autoload add the library:
$autoload['libraries'] = array('layout');
In your controller just write $this->layout->render();
The class will render the layout views/layouts/default.php and the view views/$controller.views/$method.php
In the default layout just put
<?php $this->load->view($view,$data); ?>
and thats it.
The code is
<?php
if (!defined('BASEPATH')) exit('No direct script access allowed');
class Layout
{
public $data = array();
public $view = null;
public $viewFolder = null;
public $layoutsFodler = 'layouts';
public $layout = 'default';
var $obj;
function __construct()
{
$this->obj =& get_instance();
}
function setLayout($layout)
{
$this->layout = $layout;
}
function setLayoutFolder($layoutFolder)
{
$this->layoutsFodler = $layoutFolder;
}
function render()
{
$controller = $this->obj->router->fetch_class();
$method = $this->obj->router->fetch_method();
$viewFolder = !($this->viewFolder) ? $controller.'.views' : $this->viewFolder . '.views';
$view = !($this->view) ? $method : $this->view;
$loadedData = array();
$loadedData['view'] = $viewFolder.'/'.$view;
$loadedData['data'] = $this->data;
$layoutPath = '/'.$this->layoutsFodler.'/'.$this->layout;
$this->obj->load->view($layoutPath, $loadedData);
}
}
?>
