title: Codeigniter: How to redirect properly with form validation
body: <p>I understand how to do it w/ a plain form w/o existing values, but let's say I have a view that I can call via <a href="http://domain.com/account/settings" rel="noreferrer">http://domain.com/account/settings</a>. let's say I have two fields, username, password and city, which are all pulled from the DB (except for password of course). So, if a user tries to submit the form and fails validation for whatever reason, where should I "redirect" them to? Right now, I have it showing the same view but the problem is, it pulls the info from the DB again. Should I be creating two different views?</p>
  
  <p>The second view would essentially show the information they tried to enter along w/ the error message.</p>
