            </form>

controller (controllers/bankdatel.php)

public function editbank(){

        $this->load->model('model_bankdatel');
        $data['row_bank'] = $this->model_bankdatel->selectbank($this->uri->segment(2));

        $this->load->view('template/header');
        $this->load->view('form/form_edit_bank', $data);
        $this->load->view('template/footer');
    }


    public function updatebank(){

        $arrdata = array(
                'namabank' => $this->input->post('namabank')
            );

        $this->load->model('model_bankdatel');
        $this->model_bankdatel->updatebank($arrdata, $this->uri->segment(3));
        $this->session->set_flashdata('berkas', "<script>alert('Nama Bank Berhasil Diubah');</script>");
        redirect('bankdatel');
    }

model (model/model_bankdatel.php)

public function updatebank($data, $id){
        $this->db->where('idbank', $id);
        $this->db->update('mt_bank', $data);
    }

    public function selectbank($id)
    {
        $this->db->where('idbank', $id);
        return $this->db->get('mt_bank')->row(); 
    }

Check if you are getting any value for $this->uri->segment(3) — Ropali Munshi

Your form URL is site_url('bankdatel/updatebank/'.$row_bank['idbank']). It means 1 argument is passing to function. So get $bankid like this

public function updatebank($bankid){

    $arrdata = array(
            'namabank' => $this->input->post('namabank')
        );

    $this->load->model('model_bankdatel');
    $this->model_bankdatel->updatebank($arrdata, $bankid);
    $this->session->set_flashdata('berkas', "<script>alert('Nama Bank Berhasil Diubah');</script>");
    redirect('bankdatel');
}

And use return with update query in the model

return $this->db->update('mt_bank', $data);
