Fail to update the fields in the database in codeigniter - php

Question

I'm trying to create the function to update user details. but the database transaction in the model fails. It just pops out failure message without giving any db errors or anything.
Is there a way to view db logs for debugging in model like var_dump in controller
controller
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class edit_account extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->library('session');
$this->load->helper('form');
$this->load->helper('url');
$this->load->database();
$this->load->library('form_validation');
$this->load->model('medit_account');
}
function index() {
}
function edit_dept_officer() {
$user_id = $this->session->userdata('user_id');
// retrieve data from db to edit from
$table = 'department_officer';
$user_data = $this->medit_account->get_current_user($table, $user_id);
var_dump($user_data);
$userid = $user_data[0]->OfficerID;
$data = array(
'officer_no' => $user_data[0]->officer_no,
'first_name' => $user_data[0]->first_name,
'last_name' => $user_data[0]->last_name,
'contact_no' => $user_data[0]->contact_no,
);
var_dump($userid);
//validation rules
// $this->form_validation->set_rules('officer_no', 'Officer ID ', 'trim|required');
$this->form_validation->set_rules('first_name', 'First Name ', 'trim|required');

$this->load->view('footer');
// var_dump('point');
} else {
// pass validation

$first_name = $this->input->post('first_name', TRUE);
