Hello I’m kinda new to CodeIgniter but I’ve been working with it at least 3 months and it works great. Now I’m posting this because I just cannot figure out how to solve some code in which I’m working.
I’m going straight to the point; I have this on my MY_Controller:
<?php
class MY_Controller extends CI_Controller
{
//Get user data for all controllers
public $users = array();
function __construct()
{
parent::__construct();
//Get user data to make it available for both Admin and Public Controllers
$this->load->model('User_model');
$data['users'] = $this->User_model->get_list();
//Load Menu Library
$this->load->library('menu');
$this->pages = $this->menu->get_pages();
// Brand/Logo
$this->favicon = 'https://blogpersonal.net/wp-content/uploads/2017/08/favicon-v2-150x150.png';
$this->brand = 'Some Name';
$this->description = 'Some Description';
$this->credits = 'https://blogpersonal.net/';
$this->version = '1.1.1';
}
}
class Admin_Controller extends MY_Controller
{
function __construct()
{
parent::__construct();
if (!$this->session->is_admin) {
redirect('admin/login');
}
//some code here
}
}
class Public_Controller extends MY_Controller{
function __construct(){
parent::__construct();
//some code here
$this->User_model->session_comprobate_member();
}
}
class Social_Controller extends MY_Controller
{
function __construct()
{
parent::__construct();
if (!$this->session->is_member) {
redirect('dashboard/login');
}
//some code here
}
}
As you can see I’m loading a $users variable outside the __construct function in order to make it work with the __construct function itself and with the other controllers.
So the next thing is to load the user_model and from there get the $data[‘users’] to display it in the view but WITHOUT loading it. Here is my view:
<!-- -->
<ul class="nav navbar-nav">
<?php if(!$this->session->is_member) : ?>
<li><?php echo anchor('public/users/login', 'Login'); ?></li>
<li><?php echo anchor('public/users/register', 'Register'); ?></li>
<?php elseif($users) : ?>

Here is my User_model:
<?php
class User_model extends CI_MODEL
{
function __construct()
{
parent::__construct();
$this->table = 'users';
}
public function get_list()
{
$query = $this->db->get($this->table);
return $query->result();
}
public function get($id)
{
$this->db->where('id', $id);
$query = $this->db->get($this->table);
return $query->row();
}
public function add($data)
{
$this->db->insert($this->table, $data);
}
public function update($id, $data)
{
$this->db->where('id', $id);
$this->db->update($this->table, $data);
}
public function delete($id)
{
$this->db->where('id', $id);
$this->db->delete($this->table);
}
public function login($username, $password)
{
$this->db->select('*');
$this->db->from($this->table);
$this->db->where('username', $username);
$this->db->where('password', $password);
$this->db->limit(1);
$query = $this->db->get();
if ($query->num_rows() == 1) {
return $query->row()->id;
} else {
return false;
}
}
//I need to work on these two
public function get_username($users) {
$this->db->select('id');
$this->db->from('users');
$this->db->where('username', $users);
return $this->db->get()->row('id');
}
public function get_userid($user_id) {
$this->db->from('users');
$this->db->where('id', $user_id);
return $this->db->get()->row();
}
///
public function existent_username($username) {
$query = $this->db->get_where('users', array('username' => $username));
return $query->row_array();
}
public function existent_email($email) {
$query = $this->db->get_where('users', array('email' => $email));
return $query->row_array();
}
public function session_comprobate_member() {
if ($this->session->userdata('is_member') != NULL) {
redirect('dashboard');
}
}
public function session_comprobate_admin() {
if ($this->session->userdata('is_admin') != NULL) {
redirect('admin');
}
}
}
I’ve been working with this for already three days and I’m desperate(not going to lie) . I just need help. Does somebody knows how can I do it without loading the view and just make it available for all views?; or any reference(book, video tutorial, online course).
Thanks for helping.
