hi Guys,

I started learning Code Igniter Today and i am not able to run hello world program,

SO i have Localhost, i installed apache and Mysql and everything, I tried running PHP code as well works fine,

So i did download codeigniter and put it in the localhost and try to create first controller like this….
<?php
class Blog extends Controller {

function index()
{
echo 'Hello World!';
}
}
?>

Now i go to the path http://ip/CodeIgniter/index.php/blog

and it does not print Hello world, What should i do?

What am i doing wrong?

Please help me

Does PHP works?

What does it display on screen?

Change your code to this with constructor

class Blog extends controller{
   function Blog(){
      parent::Controller;
   }
   
   function index(){
          echo "hello world";
}

}

How that helps

Each time you extend the controller you have to call the Controller constructor otherwise you wouldn’t be able to use the stuff.

if you have php 5 you can do the following for constructor

function __construct(){
        parent::Controller();
    }

Good luck!

You don’t have to, you only need to call the parent constructor if you have your own constructor

Agreed. I never use a constructor.

Thanks for correcting me. Learning something new everyday 😊

I’m not sure if the forum converted your quotes, but if I copy and paste your code, its not standard single quotes :S

They may be using the auto typography function for the posts.

I know they might be, but I was just checking he wasn’t using the wrong sort of quotes for an echo, although if he was, I’d expect an error

@codeman It’s hard to say what it could be. If PHP was working and you simply dropped in CodeIgniter, things should work unless the path’s are incorrect or something. I just used this code and it worked.

<?php

if ( ! defined('BASEPATH') )
    exit( 'No direct script access allowed' );

class Blog extends Controller
{
    function index()
    {
        echo 'hello world';
    }

}

Edit: Which, now I just noticed. The single quotes I put in this post, aren’t converted to anything else due to auto typography. So, you obviously have some funny symbols being used. Replace your quotes with actual single (or double) quotes. Do you get any kind of error message?

I just tried his original, with the funny quotes, and it gives a parse error

Parse error: parse error, expecting `','' or `';'' in C:\xampp\htdocs\project_trackr\controllers\blog.php on line 6

so thats either not the problem or he neglected to mention the error

Still Nothing Guys,

Here is my code and URL I am using

<?php
class Blog extends controller{

   function __construct(){
        parent::Controller();
    } 
   
   function index(){
          echo "hello world";
    }

} 
?>

and I am using http://my IP/CodeIgniter/index.php/blog/

I have PHP 5 running on my local Host and PHP 5 is working fine

Please help me,
Thanks,

Put an echo in your constructor, see if it even gets that far

Did you move the app or system folders around?  If you just take the system folder and drop it in the root with the index.php it should just work. Are you getting an error? What is it doing? “its not working” doesnt exactly tell us much about whats going on.

NO echo is not working either and here is my path

/root/Codeigniter/System/Controllers/Blog.php

I am not getting any error - it shows blank page with nothing - just white page, sometimes i feel errors are better than no error problems

I am not sure what ami doing wrong - i am following simple instruction form the code igniter website

why is it this complicated, By the way great help - you guys are fast in replyinh - unsually great
