Does the view exsist?

That is very true, finished code (to date);

Code:

$uri_string = $this->uri->uri_string();
$uri_string = empty($uri_string)? 'home.php' : $uri_string .'.php';
if(file_exists('./application/views/' . $uri_string) === false)
{
    show_404($uri_string);
}
else
{
    $this->load->view($uri_string);
}
