Session Codeigniter

Question

I have this normal Septssion:

foreach ($nofeatured_prods as $k) {
    $_SESSION['itens'][$k->id] = $k;
}

How do I assign equally, however, in codeigniter?

Answer 1

Use the method set_userdata() of the IC session library

To assign do:

$var = array('nome' => 'teste');
$this->session->set_userdata($var);

Or else:

$this->session->set_userdata('chave', 'valor');

To recover do:

$this->session->userdata('nome');

Loading

To load this library there are two ways, the first is to call it just where it will be used or by demand and the second let the framework already load it in all requests automatically.

First form:

$this->load->library('session');

Second form:

In the config/autoload.php file look for $autoload['libraries'] and add the element in this array session.

$autoload['libraries'] = array('session', 'database');
