That's a common mistake .
Your method is like

Code:
function edit($user_id)

{

//blah blah blah

}

But this means we are forced to provide an user id in the url , something like /user/edit/1 but if we don't provide that 1 and the url is /url/edit that of course, the $user_id var is undefined.
You need to correct this like :

Code:
function edit($user_id='')

{

   if(empty($user_id) || !is_numeric($user_id) || $user_id < 1)

   {

      redirect('users');

   }

   //continue processing because from now on we really have a valid $user_id.

}
