Undefined property: update_user::$update_model - codeigniter - php

Question

I am a noob at both PHP and codeigniter, so please be gentle.
I was messing around with this file and got this error.
Message: Undefined property: update_user::$update_model
Filename: controllers/update_user.php
Fatal error: Call to a member function update_user_id() on null in C:.....update_user.php on line 20
here is my code
<?php
class update_user extends CI_Controller{
function __construct(){
parent::__construct();
$this->load->model('user_model');
}
function show_user_id() {
$id = $this->uri->segment(3);
$data['users'] = $this->update_model->show_users();
$data['single_user'] = $this->update_model->show_user_id($id);
$this->load->view('update_view', $data);
}
function update_user_id() {
$id= $this->input->post('did');
$data = array(
'userName' => $this->input->post('dname'),
'userPass' => $this->input->post('dpass'),
);
$this->update_model->update_user_id($id,$data);
$this->show_user_id();
}
}
this is line 20
$this->update_model->update_user_id($id,$data);
anybody can give any pointers to what is wrong?
thanks in advance

Answer 1

This line:
$this->update_model->update_user_id($id,$data);
Should be:
$this->user_model->update_user_id($id,$data);
Also, every other place where you have used update_model, it should be changed to user_model.
This is assuming that you have only a user_model and no update_model. That's what your code shows.

Answer 2

The error is indicating the problem clearly. you are using update_model model which you haven't loaded in your update_user Controller. If this is it than load the update_model like this $this->load->model('update_model'); else change the code:
$this->update_model->update_user_id($id,$data);
to
$this->user_model->update_user_id($id,$data);
Also please share your model code if there is any issue.
