Continuous Loop in form validation

[eluser]yorvik[/eluser]
Ok I edited the suggestions, now I am using

Code:

if($this->form_validation->run() == FALSE)
{
redirect('/art_controller/index/', 'refresh');
}

This works but I am still not able the show the message errors on my view. Is there any way I could realise this

My ajax url is:
url: ...art_controller/input/22
My 3rd segment is the ID of the Current record I am updating in the database.
