1. The template library

Create a template.php in your system/applications/libraries/ folder.

template.php =

Code:
&lt;?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class template {

        var $template_data = array();

        function set($name, $value)

        {

            $this->template_data[$name] = $value;

        }

        function load($template = '', $view = '' , $view_data = array(), $return = FALSE)

        {               

            $this->CI =& get_instance();

            $this->set('contents', $this->CI->load->view($view, $view_data, TRUE));            

            return $this->CI->load->view($template, $this->template_data, $return);

        }

}

/* End of file Template.php */

/* Location: ./system/application/libraries/template.php */

2. Load the library in you controller(s):

Code:
$this->load->library('template');

or you can autoload it in your config/autoload.php:

Code:
$autoload['libraries'] = array('template');

3. Create a new template.php file in your system/applications/views folder. The contents of that template.php can be something like this:

Code:
&lt;html&gt;

 &lt;head&gt;

   &lt;!-- add your javascript includes here --&gt;

   &lt;!-- add your css includes here --&gt;

   &lt;!-- etc --&gt;

 &lt;/head&gt;

 &lt;body&gt;

 <div id='header'>

    &lt;!-- include your header view here --&gt;

    &lt;?php $this->load->view('header'); ?&gt;

 </div>

 <div id='whateverworks'>

   &lt;?= $contents ?&gt;

 </div>

 <div id='footer'>

    &lt;!-- include your footer view here --&gt;

    &lt;?php $this->load->view('footer'); ?&gt;

 </div>

 &lt;/body&gt;

&lt;/html&gt;

Everytime you load a view, you will load this template view and and another where the $content is. Here's how, in your Controller, instead of using:

Code:
$this->load->view('blog/show_post's);

you can now use

Code:
$this->template->load('template', 'blog/show_posts');

or

Code:
$this->template->load('template', 'blog/show_posts', $data); // :)

That will load the template view file with the view (blog/show_posts) included.

NOTE: make sure the variable name (here that is '$contents' in your template view, is the same as the one you use in the load() function in your template library in:

Code:
$this->set('contents', $this->CI->load->view($view, $view_data, TRUE));

Hope that helps!

I'm trying the same code with a few changes... but it give me an error..
I follow all the first 3 steps, and of course i use 'contents' in both template.php in libraries and views..
it says

Severity: Notice

Message: Undefined variable: contents

Filename: views/template.php

Line Number: 16

one thing that i change is the
$this->template->load('template', 'blog/show_posts'); part
i change it with
$this->template->load('template','failure');

i put my failure.php in application/views and only consist on word "failure", but it don't work.. Did i miss something?
