you can use callback function in validation.
if you have not idea about callback please read this userguide.

How to write callback function for checking if user is entering space between first name and last name???

I think you have not read user guide Every things are described on it.
in your case your call back function will be shaw in bellowed Example.
may this help you.

Code:

//set your validation rules
$this->form_validation->set_rules('name', 'Full Name', 'callback_space_check');

your call back function will be like...
public function space_check($str) {
   $pos = strrpos($str, " ");
   if ($pos === false) { // note: three equal signs
    // not found...
    $this->form_validation->set_message('space_check', 'The %s field can not contain SPACE BTW First name and Last Name');
    return FALSE;
  }
  else  {
    return true;
  }
}
