use this:

It just means the password has not been posted from the form

A PHP Error was encountered Severity: Notice
Message: Undefined property: Account::$Account_model

$data['books']=$this->Account_model->get_all_acc();

}
this is my model :
class Account_model extends CI_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
I want to deleting my data in the table, but i can't delete the data because of this problem. Error Number: 1064
This is my Controller
class Dosen extends CI_Controller
{
public function __construct()
{
parent ::__construct();
$this->load->library('form_validation');
$this->load->model('Dosen_model');
}
public function index()

$this->form_validation->set_rules('nama','Nama','required');
if ($this->form_validation->run()==FALSE)

}
}
public function hapus($nip)
{
$this->Dosen_model->hapusDataDosen($nip);
$this->session->set_flashdata('flash','Dihapus');
redirect('Dosen');
}
And this is my Model
<?php

}
public function hapusDataDosen($nip)
{
$this->db->where('nip',$nip);
$this->db->delete('daftar_dosen',$data);

the output is :

Line Number: 691
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));
}

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

{

{
$this->db->where('username',$username);

$query = $this->db->get('users')
if($query->num_rows() > 0){

$this->load->view('templates/header',$data);
$this->load->view('news/view',$data);
$this->load->view('templates/footer');
}
}
and here is a picture of my file structure
im trying my best to learn and debug but i dont know what it could be.
Maybe, database library is not loaded. you have to load database library.
application / config / autoload.php
$autoload['libraries'] = array('database');

post the code for model class and, in your model, change this
$this->db->where('username,$username');
to
$this->db->where('username',$username);
or
$this->db->where("username,$username");// single quote to double quote
in function signupchk($username)
Where is your model class? You can try this:
<?PHP
defined('BASEPATH') OR exit('No direct script access allowed');
class Your_model_name extends CI_Model{
function __construct ()
{
parent ::__construct();
$this->load->database();
}
function signupchk($username)
{
$this->db->select('username');
$this->db->from('users');
$this->db->where('username,$username');
$sql = $this->db->get();
if($sql && $sql->num_rows() > 0)
{
return false;
}
else
{
return true;
}
}
function signup($data)
{
$data = array(
'rusername'=> 'username',
'rpassword'=> 'password',
'remail' => 'email',
'rphone' => 'phone',
'rgender' => 'gender',
'rqualify' => 'qualification',
);
$sql = $this->db->insert('users',$data);
return $sql;
}
}
}
?>
You forget to load your model.
Add this line in your insert function:
$this->load->model('Storemdl');
