session - PHP problem with "__php_incomplete_class"

Question

I'm developing a website with CodeIgniter and have created a User and a session:

$user->first_name = 'Gerep';
$user->gender = 'M';
$user->age = '26';


$this->session->set_userdata('user', $user);

But when I try to access the session object:

echo $this->session->userdata('user')->first_name;

It returns me a error: Object of class __PHP_Incomplete_Class could not be converted to string

I have always worked like that and never had that problem.

Thanks!

Answer 1

The class definition had not been loaded, when PHP tried to deserialize the object in the session.

You can solve your problem by employing Autoloading.
