Little problem

[eluser]jabga[/eluser]
Hi all, I am start using CI and I am also a PHP beginner.

I am trying to create a simple database driven brochure web page.

Please tell me.
I would like to get number of displaying news from GET or POST varuables. How can I do this?

This is controller

Code:

function index()
    {
        $data['limit'] = 10;
        $this->load->view('header', $data);
        $this->load->view('menu', $data);
        $this->load->view('left', $data);
        $this->load->view('frontpage', $data);
        $this->load->view('footer', $data);
}

I would like to change 1 number to $_GET['id'].
This is my view page code

Code:

$query = $this->db->get('news', $limit);
foreach ($query->result_array() as $row)

And I am trying to write my url like this

Code:

http://localhost/CodeIgniter/index.php/welcome/blog?id=1

this shows me an error 404 page
Please correct me how can I mix get or post var and url and database code?

This url is working ok

Code:

http://localhost/CodeIgniter/index.php/welcome/blog
