Ok, i'm new in this domain, and i want in this topic to expose my problems that i'll receive for this framework.

I buy a domain: http://earth-war.eu/ and i tried to make the samples from video tutorials where i'll learn to make my own blog.

For the first video i've received some errors:
first said that:
Fatal error: Class 'Controller' not found in /home2/earthwar/public_html/Blog/application/controllers/blog.php on line 3

for the next code:
<?php

class Blog extends Controller{

function index()
{
echo'Hello World'
}

}

?>

I replaced Controller() with CI_Controller and worked, but when i tried to create the constructor i received this:

Fatal error: Call to undefined method CI_Controller::CI_Controller() in /home2/earthwar/public_html/Blog/application/controllers/blog.php on line 7

I replaced with Controller but same error undefined method CI_Controller::Controler().
The code:
<?php

class Blog extends CI_Controller{

function Blog()
{
parent::CI_Controller();
}
function index()
{
$data['title']="My Blog Title";
$data['heading']="My Blog Heading";
$data['todo']=array('Clean house','eat lunch','call mom');
$this->load->view('blog_view',$data);
}

}

?>

Please help i'm a little stuck on this error and i don't know what to do.
Thanks a lot for future help.
One more thing.. if you see errors in my grammar or my exprimation pls correct me if you have time). Thanks again

You need to use __construct(), not the class name.

Code:

class Blog extends CI_Controller {

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

}

http://ellislab.com/codeigniter/user-gui...llers.html

If you intend to use a constructor in any of your Controllers, you MUST place the following line of code in it:

Code:

parent::__construct();

Ok..now i began the work and i've got another problem.
I've created a login page and after the member_area page is loading, in my session my username variable is empty.
I've tried two sollutions:
First:
This is where my function is define.
function members_area()
{
$data['main_content']='members_area';
$data['username']=$this->session->userdata('username');

$this->load->view('includes/template',$data);
//$this->load->view('members_area');
}

This is my view_page:
<div id="mainContent">

<div id="userPanel">
<h3>Account Details</h3>
Wellcome: &lt;?php $username?&gt;
</div> &lt;!-- se inchide userPanel--&gt;

</div>&lt;!-- se inchide mainContent--&gt;

and second ideea is:
function members_area()
{
$data['main_content']='members_area';

$this->load->view('includes/template',$data);
//$this->load->view('members_area');
}

This is my view_page:
&lt;?php $username=$this->session->userdata('username');
<div id="mainContent">

<div id="userPanel">
<h3>Account Details</h3>
Wellcome: &lt;?php $username?&gt;
</div> &lt;!-- se inchide userPanel--&gt;

</div>&lt;!-- se inchide mainContent--&gt;
Not Works.

above this member_area function i have another function:
function is_logged_in()
{
$is_logged_in=$this->session->userdata('is_logged_in');
if(!isset($is_logged_in)||$is_logged_in !=true)
{
echo 'You don\' have permission to access this page. <a href="../login">Login</a>';
die();
}
}

and works great.
I define my session variables here:
if($query)
{
$data=array(
'username'=>$this->input->post('username'),
'is_logged_in'=>true
);
$this->session->set_userdata($data);
redirect('site/members_area');

}

i discover that my problems is in this code:

&lt;?php
$user=$this->session->userdata('username');
echo $user;?&gt;
//$username=$this->session->userdata('username');

<div id="mainContent">

<div id="userPanel">
<h3>Account Details</h3>
Wellcome: &lt;?php $user?&gt;
</div> &lt;!-- se inchide userPanel--&gt;

</div>&lt;!-- se inchide mainContent--&gt;
