Controller

            defined('BASEPATH') OR exit('No direct script access allowed');

            class productdisplay_ctrl extends CI_Controller {

                public function __construct() {
                    parent::__construct();

                    $this->load->helper('url');
                    $this->load->model("productdisplay_model");
                }

                public function productfetch(){

                    $this->load->model("productdisplay_model");
                    $result = $this->productdisplay_model->fetchData();
                    $data['name'] = $result->sub3_category_name;

                    $this->load->view('home', $data);

            public function fetchData() {

              $this->db->select('*');
                $this->db->where($where);
                $this->db->order_by('rand()');
                $this->db->from('sub3_category');
                $query = $this->db->get();

                if ($query->num_rows() > 0) {

                    return  $query->row();
                }
                return false;

Change in model.like this.use row() which returns result in object format having matched row.so that you can access columns using arrow operator.

And what about your $where variable.set it.

public function fetchData() {

            $this->db->select('*');
            $this->db->where($where);
            $this->db->order_by('rand()');
            $this->db->from('sub3_category');
            $query = $this->db->get();

            if ($query->num_rows() > 0) {

                return  $query->row();
            }
            return false;
        }

inside the foreach loop, remember $row var is a object

if ($query->num_rows() > 0) {
            foreach ($query->result() as $row) {
                $data[] = $row->field;
            }
