Introduction
This is a cake-like layout/view system…

/application/libraries/Layout.php
<?php

Usage
Loading the library
You can use it in two ways. First and obvious is to place the following line in the controller’s constructor function.
$this->load->library('layout', 'layout_main');
The second is by enabling codeIgniter to autoload the library by editing /application/config/autoload.php
$autoload['libraries'] = array('layout');
$this->layout->view('/shop/view_cart', $data);
Master layout
/application/views/layout_main.php
Your view file must use $content_for_layout. For example:
<html>
<head>
<title><?=$title_for_layout?></title>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<link rel="stylesheet" href="/css/main.css" type="text/css" />
</head>
<body>
<div id="pagewidth" >
<div id="header" ><img src="/images/header.jpg" width="700" height="200"></div>
<div id="wrapper" class="clearfix" >
<div id="twocols" class="clearfix">
<?php echo $content_for_layout?>
</div>
</div>
<div id="footer" > Footer </div>
</div>
</body>
</html>
