Display username logged in with Codeigniter

Question

How do I display the username logged in to the system?

The function that authenticates and creates the session is this:

function verificar()
{
    $this->load->model('tbdaluno');
    $check = $this->tbdaluno->validar();
    if($check)
    {
        $this->session->set_userdata('aluno', $check);
        redirect('dashboard');
    }
    else
    {
        redirect('');
    }
}

Answer 1

Within your condition of if/else creates a variable for the SESSION which was set, and passes the variable in the $load, or in a very rustic way, in its View use $_SESSION['aluno'].

function verificar()
{
    $this->load->model('tbdaluno');
    $check = $this->tbdaluno->validar();
    if($check)
    {
        $dados['aluno'] = $this->session->set_userdata('aluno', $check);
        redirect('dashboard',$dados);

    }
    else
    {
        redirect('');
    }
}
