This series of articles is aimed at demonstrating how to build a blog application with the Code Igniter PHP framework, which relies on the functionality offered by the MVC approach to create full-featured PHP programs. Thus, if you’re interested in learning how to build a program like this, then start reading this tutorial now! It is the fifth part of the six-part series.

TOOLS YOU CAN USE

Having already styled the web page that shows all of the blog entries, it’s time to list the full source code that comprises the blog program, so you can test and eventually change any of its files. Here’s how the blogger looks after including the CSS styles shown in the previous section:

// definition for 'blogger.php' file (located at /system/application/controllers/ folder)

class Blogger extends Controller{

function Blogger(){

// load controller parent

parent::Controller();

// load database class and connect to MySQL

$this->load->database();

// load pagination library

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

// load helper

$this->load->helper('url');

}

// display all blog entries

function blogs(){

$data['title']='Blog Entries Listing';

$data['result']=$this->db->get('blogs',3,$this->uri->segment(3));

// set pagination parameters

$config['base_url']='http://127.0.0.1/codeigniter/index.php/blogger/blogs/';

$config['total_rows']=$this->db->count_all('blogs');

$config['per_page']='3';

$config['full_tag_open']='<div id="paginglinks">';

$config['full_tag_close']='</div>';

$this->pagination->initialize($config);

// create pagination links

$data['links']=$this->pagination->create_links();

// load 'blogs_view' view

$this->load->view('blogs_view',$data);

}

// display all blog comments

function comments(){

$data['title']='Blog Comments Listing';

$this->db->where('blog_id',$this->uri->segment(3));

$data['result']=$this->db->get('blogs_comments');

// load 'blogs_comment_view' view

$this->load->view('blogs_comment_view',$data);

}

// insert new blog comment

function insert_comment(){

$this->db->insert('blogs_comments',$_POST);

redirect('blogger/comments/'.$_POST['blog_id']);

}

// definition for 'blogs_view.php' file (located at /system/application/views/ folder)

Now that you have the complete source code of this MySQL-driven blog application, don’t you feel satisfied? You should, because at this moment you have the chance to play around with the source files. Whatever you do, one thing is for sure: fun is already guaranteed!

Final thoughts

In this fifth chapter of the series, I demonstrated how to polish the visual presentation of the web blogger by styling the web document that displays blog entries. As you saw before, this process was extremely straightforward and didn’t require any special programming skills.

In the last article, I’ll be styling the web documents that shows user-submitted comments, in this manner completing the development of this blogger application.

Now that you’ve been warned, don’t miss the final part!
