I think this is what you are trying to do...
class Alias extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->database();
$this->load->helper('url');
}
public function index(){
echo 'Default page!';
}
public function get($alias)
{
$this->db->from('users')->where(array('username' => $alias));
$query = $this->db->get();
if ($query->num_rows() > 0){
//This means that a row was returned from the database and their is a user that exists with that name
redirect("/pages/$alias");
}
else{
echo 'There is no user that exists with that username';
}
}
public function pages($alias){
echo "Hey $alias!";
}
}
//Routes
$route['default_controller'] = "alias";
$route['404_override'] = '';
$route['pages/:any'] = "alias/pages/$1";
$route[':any'] = "alias/get/$1";
In the constructor it loads the database class and the URL helper. In the index() method is uses the database to select a row from the "users" table where their username is the $alias. Then it checks with an if statement if a row was returned from the database. If a row was returned that means a user exits and to redirect to /pages/username. Else it will echo saying no one exits with that username.
Make sure to change the database info match your database setup as well as make sure $active_record is set to TRUE in the database config file.
