Update query is altered by safari???

Thanks for your replies.
I had stripped my code to make the post smaller.
Here is the whole controller:

Code:

function preferred()
    {
        $this->load->helper(array('form', 'url'));
        $this->load->library('form_validation');
        $this->form_validation->set_rules('preferred', 'preferred', 'required|trim|xss_clean');
        if ($this->form_validation->run() == FALSE) {
            echo 'Error';
        }else{
        $newdata = $_POST['preferred'];
        
        $id = $this->session->userdata('uid');
        $this->db->where('id',$id);
        
        $this->db->update('members',$_POST);
        //$this->db->query("UPDATE members SET preferred = '$newdata' WHERE id = '$id'");
        
        $this->session->set_userdata('preferred',$newdata);
        
        echo htmlentities($newdata);;
        
        }
    }

The whole picture may help. This is an ajax call.
the form has one field 'preferred'.

The JS script that sends the info to the controller is:

Code:

function updateit(){
     var url = 'index.php/members/preferred';
     var pars = $('preferred_form').serialize(true);
     var target = 'new_preferred';
     var myAjax = new Ajax.Updater(target, url, {method: 'post', parameters: pars});
}
var pageInit = function() {
   Event.observe('preferred_form', 'submit', function(e) {
      updateit();
      e.stop();
      
   });
}

document.observe('dom:loaded', pageInit);

I got the same results with validation included.
Help. Thanks
