I have noticed that when I don't validate an input feild, it gets vanished.

kjanko try this code in place of your login function:

Code:

public function login()
{
    $this->output->enable_profiler(TRUE);
    $this->load->library('trinity');
    $this->load->library('session');
    
    $this->load->library('form_validation');
    $this->form_validation->set_rules('username', 'Username', 'trim');
    $this->form_validation->set_rules('password', 'Password', 'trim');
    
    if ($this->form_validation->run() == FALSE)
    {
        //You will never reach this code. It is just of debugging purpose;
        echo "In put data not valid";
        return;
    }
    
    $username = $this->input->post('username');
    $password = $this->input->post('password');
    var_dump($username);
    var_dump($password);
    if($this->session->userdata('logged_in'))
    {
        show_error('You are already logged in!');
    }
    else
    {
        $this->trinity->Login($username, $password);
        redirect('home');
    }
}
