title: Use CodeIgniter form validation in a view
body: <p>I have footer view that's included on all my pages which contains a form. I would like to be able to make use of CI's form validation library to validate the form. Is that possible?</p>
  
  <p>Currently the form posts back to the current page using the PHP_SELF environment variable. I don't want to get it to post to a controller because when validation fails it loads the controller name in the address bar, which is not the desired behaviour.</p>
  
  <p>Any suggestions gratefully received.</p>
  
  <p>Thanks,</p>
  
  <p>Gaz</p>
