Partial Library will help you develop your application faster, no need for template engines here!

Step one, copy and paste the library to application/libraries/Partial http://pastebin.com/wqNQBeE1

Step two, create a layout file.
application/views/layout_three_column.php

Code:
<!DOCTYPE html>

&lt;html&gt;

&lt;head&gt;

&lt;title&gt;Three Columns&lt;/title&gt;

&lt;/head&gt;

&lt;body&gt;

<! -- position left --&gt;

<div>

&lt;?php $partial = $this->partial->load('left'); ?&gt;

&lt;?php foreach($partial as $key => $value); ?&gt;

&lt;?php echo $value; ?&gt;

&lt;?php endfor; ?&gt;

</div>

&lt;!-- position right --&gt;

<div>

&lt;?php $partial = $this->partial->load('right'); ?&gt;

&lt;?php foreach($partial as $key => $value); ?&gt;

&lt;?php echo $value; ?&gt;

&lt;?php endfor; ?&gt;

</div>

&lt;/body&gt;

&lt;/html&gt;

Step three, add some partial views.
application/views/featured.php

Code:
&lt;?php if(isset($featured_articles)): ?&gt;

<h2>Featured Articles</h2>

&lt;?php echo $featured_articles; ?&gt;

&lt;?php endif; ?&gt;

application/views/popular.php

Code:
&lt;?php if(isset($popular_articles)): ?&gt;

<h2>Popular Articles</h2>

&lt;?php echo $popular_articles; ?&gt;

&lt;?php endif; ?&gt;

Step four, modify the library $uri property to match your default controller!
application/libraries/Partial.php

Code:
$this->uri = ($uri)? $uri : 'home';

Step five, add your partial view paths to $this->views
application/libraries/Partial.php

Code:
$this->views = array('featured', 'popular');

Step six (optional), create config.php - views will be loaded from config file
application/config/partial.php

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

$config = array(

'articles' => array(

    'left' => array(

        'featured',

     ),

     'right' => array(

         'popular',

     ),

),

'articles/latest' => array(

    'left' => array(

        'featured',

     ),

     'right' => array(

         'popular',

     ),

));

/* End of file partial.php */

Step seven, create a controller
application/controllers/articles.php

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

class Articles extends CI_Controller

{

    public function __construct()

    {

        parent::__construct();

    }

    public function index()

    {

        $this->load->library('partial');

        // $articles = $this->articles_model->latest_articles();

        $featured_articles = '<p>Suas simul oblique ne eum, cum atqui paulo accumsan te.</p>'

        $popular_articles = '<p>Lorem ipsum dolor sit amet, partem explicari eum isit.</p>'

        $this->partial->replace(array(

            'left' => array(

                'featured_articles' => $featured_articles,

            ),

            'right' => array(

                'popular_articles' => $popular_articles,

            ),

        ));

        $this->load->view('layout_three_column');

    }

    public function latest()

    {

        $this->load->view('layout_three_column');

    }

}

Want a shorthand method?

Code:
$this->partial->replace(array('left' => 'featured_articles'));

How about loading partials into multiple positions?

Code:
$this->partial->replace(array(

    'left' => 'featured_articles',

    'right' => 'popular_articles',

    ),

));

Don't want your article to show when you're paginating comments? No problem!

Code:
if($pagination_offset > 0)

{

    $this->partial->trim_begin('left');

}

What's that you say? User is not logged so you want to remove a partial?

Code:
if( ! $this->session->userdata('logged_in')) // or something to that extent

{

    $this->partial->remove(array(

        'left' => array(

            'featured',

        ),

    ));

}

I'm actively developing this class, I'll update regularly, I've got it working in production. I remove the "die()" statement as these are for development. When I get the time I'll intergrate it with CI's ENVIRONMENT constant.

I'm thinking about implementing a role based access system for the $views property too. Suggestions welcome!
