Pagination URI

[eluser]Perkin5[/eluser]

Code:

userdate('current')

was the entire URI - however, having asked the question, I had another idea.
I used this:

Code:

$this->session->set_userdata('current',$this->uri->segment(3));

Which appears to have successfully grabbed the third segment. So now I can do:

Code:

redirect('shop/item/'.$this->session->userdata('current'));

and that seems to work. Am I doing that the right way?
