I'd like to do a thing

The user log-in the site. Complete the first page of the form, after when insert the data e click on a button I will be redirect to another page of the form

I tried this code

Answer 1

Try the following, it will set the location header of the response to the location of your second page:

if($user->id)
{
    header("Location: http://www.mysite/second-page-form");
    exit;
}

You do not need to check for the session. You can simply detect if the user is logged in:

$user = JFactory::getUser();
$app  = JFactory::getApplication();
if(!$user->guest)
{
    $app->redirect(JRoute::_('URL GOES HERE STARTING WITH index.php'), false);
}
