Pagination URI

[eluser]Perkin5[/eluser]
I have set up pagination for my project and it works fine. But when I navigate away from the 'paginated page', I want to be able to return to the same page. I note that the URI has the offset added to it and I have used this:

Code:

$this->session->set_userdata('current',current_url());

to grab that uri. But then if I try to navigate to

Code:

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

the page can't be found - because of the offset.

I'm sure I'm setting about it the wrong way but I've thought about it quite a bit and I can't work it out. Can anyone advise please?

What is been returned by the

Code:

userdata('current')

?

[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?
