this is my model :

var $table = 'books';
public function acc_add($data) {
$this->db->insert($this->table,$data);
return $this->db->insert_id();
}
public function get_all_acc() {
$this->db->from('books');
$query = $this->db->get();
return $query->result();
}
Try to change your function construct to this one :
public function __construct() {
parent::__construct();
$this->load->model('Account_model');
}
because the construct function require double underscore and you just typing one underscore

The error message is very clear
Message: Undefined variable: data
In other words, somewhere there is a variable $data that is not defined.
Where in your code is $data found? The answer: In the function hapusDataDosen() in the call to $this->db->delete('daftar_dosen',$data);
It is hard to know exactly what you are trying to do. My guess is all you need to do is change
$this->db->delete('daftar_dosen', $data);
to
$this->db->delete('daftar_dosen');
Try this
public function hapusDataDosen($nip){
$this->db->where('nip',$nip);
$this->db->delete('daftar_dosen');
}
OR
public function hapusDataDosen($nip){
$this->db->delete('daftar_dosen', ['nip' => $nip]);
}
Don't use $data because
You are not passing it to model function
It is unnecessary to delete a record from DB
Try This --
In Model
public function hapusDataDosen($nip)
{
$this->db->where('nip',$nip);
$this->db->delete('daftar_dosen',$nip);
}
public function hapusDataDosen($nip){
$this->db->delete('daftar_dosen',array('nip'=>$nip));
}
This is my Model:

Hope this will help you :
Your controller should be like this :
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Login extends CI_Controller {
public function __construct(){
parent::__construct();
//$this->load->model('User');
$this->load->helper('form');
$this->load->library('form_validation');
$this->load->helper('url');
$this->load->database();
$this->load->model('U_Model');
}
public function index(){
$this->load->view('header');
$this->load->view('login');
$this->load->view('footer');
}
/*added public before loginp*/
public function loginp(){
$username = $this->input->post('username');
$password = md5($this->input->post('password'));
/*md5 not recommended*/
$data = $this->U_Model->loginf($username, $password);
if( ! empty($data))
{
$this->session->set_userdata('sid',$data['id']);
$this->session->set_userdata('sname',$data['name']);
$this->session->set_userdata('username',$data['username']);
redirect('login/home');
}else{
$this->session->set_flashdata('emsg','Please Enter Your Correct Name And Password');
redirect('login/home');
}
}
public function home(){
$this->load->view('home');
}
}?>
Change your model like this
<?php
class U_Model extends CI_Model
{
public function loginf($username,$pass)
{
$this->db->where('username',$username);
$this->db->where('password',$pass);
$query = $this->db->get('users')
if($query->num_rows() > 0){
return $query->row_array();
}else{
return false;
}
}
}
?>
<?php
class U_Model extends CI_Model
{
public function loginf($username,$pass)
{
$this->db->where('username',$username);
$this->db->where('password',$pass);
$query = $this->db->get('users')
if($query->num_rows() > 0){
return $query->row_array();
}else{
return false;
}
}
}
?>

How to fix this error ?
Load the model like this
$this->load->model('Input_model','input_model'); //here input_model is alias name
$this->load->model('Input_app','input_app'); //here input_app is alias name
(or)
$this->load->model(array('Input_model','input_app')); // pass as array mutiple modal .in below i'm using this one
remove result() in controller while calling model because in model your returning result() so in controller no need to call it again.
$load['pilihkategori'] = Input_model->pilihkat();
Controller :
public function index()
{
$load['pilihkategori'] = Input_model->pilihkat();
$this->load->view('input_view',$load);
}
Model :
public function pilihkat()
{
$this->db->select('*');
$this->db->from('referensi_kategori');
$this->db->join('referensi_kategori','referensi_kategori.id_kategori = data_aplikasi.id_kategori','left');
$query = $this->db->get();
return $query->result();
}
In your controller need to change two things.
1.Load more than one models like this.
$this->load->model(array('Input_model','input_app'));
2.Remove result() Because you already done it in model.
public function index()
{
$load['pilihkategori'] = $query->Input_model->pilihkat();
$this->load->view('input_view',$load);
}
this is my controller class
public function _construct()
{
parent::_construct();
$this->load->model('customer_model');
}
public function create()
{
$this->load->helper('form');
$this->load->library('form_validation');
$this->form_validation->set_rules('name', 'Title', 'required');
$this->form_validation->set_rules('address', 'text', 'required');
if ($this->form_validation->run() === FALSE)
{
$this->load->helper('url');
$this->load->view('templates/header');
$this->load->view('master/customer');
}
else
{
$this->customer_model->register();
//$this->load->view('news/success');
}
}
}
and this is my moodel class
class Customer_model extends CI_model
{
public function _construct()
{
$this->load->database();
}
public function register()
{
$data = array(
'name' => $this->input->post('name'),
'address' => $this->input->post('address')
);
return $this->db->insert('registration', $data);
}
}

in controller & model, try changing:
public function _construct() {

to
public function __construct() { //double underscore
