Passing critical data from page to page with codeigniter

[Whilliam]

Hey guys. I need your advice on how to pass critical data from page to page. It's just one data. It's an ID from a list. It has to be secure because this data needs to be concealed.
I've used: the anchor tag. I did it like this. anchor($link . $row->jobid, $row->title);
Obviously, this is not feasible because the id can be seen in the URL and people can manipulate it. The function of this is to add, delete or edit data in the database so I can't take it for granted.
If there's any other implementation for this other than using session, I would like to hear it.
