[solved]cant set cookies

[eluser]Bianca Migueis[/eluser]
trying to update an existing website to codeigniter but got stuck at the login function... the if statement works since im redirected to the hoome page with the right password and username but for some reason it wont create a cookie... any thoughts... please?

Code:

public function authorize()
    {
        $this->db->where('username', $_POST['username']);
        $this->db->where('password', $_POST['password']);
        $data['query'] = $this->db->get('user');
        
        if ($data['query']->num_rows == 1)
        {
            $username = array(
                  'name'    => 'username',
                  'value'   => $_POST['username'],
                  'expire'  => '',
                );
            $password = array(
                  'name'        => 'password',
                  'value'       => $_POST['password'],
                  'expire'      => '',
                );
            $this->input->set_cookie($username);
            $this->input->set_cookie($password);
            
            redirect('home');
        }
        else
        {
            $this->session->set_flashdata('msg', 'Invalid Username or password.');
            
            redirect('signin');
        }
    }
