Completing a Blogging Application with the Code Igniter PHP Framework - Showing the blogging application’s full source code (
Page 4 of 4 )
As I mentioned in the section that you just read, below I listed the complete source code of this blog application, so you can play around with it and introduce your own improvements. Here it is:
// 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 at your disposal the complete source code of this MySQL-driven blogger, feel free to make your own changes and improvements. This will give you a more solid background in working with Code Igniter. If you’re like me, then you have a lot of fun ahead!
Final thoughts
Sad but true, we’ve come to the end of this series. Hopefully, after reading its tutorials, you’ll have a clear idea of how simple it is to build a database-driven application with Code Igniter.
Of course, a framework like this may not fit all of your needs, particularly when it comes to developing large-scale web programs. If you create small and middle-sized web sites frequently, however, Code Igniter is, in my opinion, one of the best frameworks available today.
I'll see you in the next PHP development tutorial!
