CodeIgniter Controller problem - php

This is my AdminBase.php
<?php
class AdminBase extends Controller{
public function __construct(){
parent::Controller();
$admin = $this->session->userdata('username');
if(!isset ($admin)){
redirect('/Site/Home');
}
}
}
And this is my Admin Controller :-
<?php
class Admin extends AdminBase{
public function index(){
echo "You are in Admin panel!!";
}
}
When i browse to Admin controller, i get this error :-
Fatal error: Class 'AdminBase' not found in C:\Program Files\wamp\www\College\application\controllers\Admin.php on line 3

You need to put this line on top of Admin.php
<?php
// Include Base Controller
include ('AdminBase.php');
class Admin extends AdminBase{
public function index(){
echo "You are in Admin panel!!";
}
}
Also your base admin class should be like
<?php
class AdminBase extends Controller{
public function __construct(){
parent::Controller();
$admin = $this->session->userdata('username');
if(empty($admin)){
redirect('/Site/Home');
}
}
}
Thanks

There is another way to do that just created filename MY_Controller.php at application/libralies
and then create like this
<?php
class AdminBase extends Controller {
public function __construct(){
parent::Controller();
$admin = $this->session->userdata('username');
if(!isset ($admin)){
redirect('/Site/Home');
}
}
}

Add another controller in codeigniter

Hello I'm currently facing a problem of adding another controller and the problem is that
I have 2 controllers
class 1st_Controller extends CI_Controller {
}
and
class 2nd_Controller extends CI_Controller{
my 2 models are working perfectly fine and the only problem is that I need to call 1 model per each controller
for example
1st controller is for 1st model and 2nd controller is for 2nd model.
Now what I've tried so far is
class 2nd_Controller extends 1st_Controller {
public function __construct()
{
header("Access-Control-Allow-Origin: *");
parent::__construct();
$this->load->model('2nd_model','2ndmodel');
$this->load->helper('url');
$this->load->library("pagination");
$this->load->library("session");
}
public function index()
{
$data['title'] = 'System Login';
$get_all_inv = $this->2ndmodel->get_all();
$data["tryvariable"] = $get_all_inv;
$this->template->load('default_layout','contents','myview2nd', $data);
}
}
I tried echo in my view like this
<?php echo $tryvariable; ?>
but no luck because the error says that it is an undefined variable .
Your second controller can't be define cause it's not define as subclass_prefix in your codeigniter application.
class 2nd_Controller extends 1st_Controller { //codeigniter don't recognize this.
}
The simpliest way to solve your problem is.. the fact that you can call multiple models in 1 Controller.
so you can have:
class 1st_Controller extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('1st_model','1stmodel');
$this->load->model('2nd_model','2ndmodel');
}
}
or call just once.
class 2nd_Controller extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('2nd_model','2ndmodel');
}
}
Hope that helps.
So what I did was write like this on my route to have my 2nd_Controller working
$route['default_controller'] = '1st_Controller';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
$route['2nd_Controller'] = '2nd_Controller';
Now everything is working perfectly. Thanks for all the help

How to load view file in core functions in codeigniter

Am trying to load view file in application/core/MY_Controller.php but its giving as follows.
Message: Undefined property: Edustaticlanding::$load
Filename: core/MY_Controller.php
Function is as follows in MY_Controller.php
function menu(){
$arrr = array();
return $arrdata['menu'] = $this->load->view('menu',$arrr,true);
}
And am calling this function in controller(Edustaticlanding.php) as follows.
function __construct(){
$this->menucontent = $this->menu();
print_r($this->menucontent); die;
}
Pls correct me.. where its going wrong.. thanks
On application/core/MY_Controller.php
Add public $data = array() like below
<?php
class MY_Controller extends CI_Controller
{
public $data = array();
public function __construct()
{
parent::__construct();
$this->data['menu'] = $this->menu();
}
public function menu(){
return $this->load->view('menu', NULL, TRUE);
}
}
On the controller then once add public $data = array(); you can access the menu on view
You have to use $this->data now on controller
<?php
class Example extends MY_Controller {
public $data = array();
public function index() {
$this->data['title'] = 'Welcome to Codeigniter';
$this->load->view('example', $this->data);
}
}
On the example view now you can echo
<?php echo $menu;?>
Add extends CI_Controller to your core controller like following codes:
class MY_Controller extends CI_Controller {
Please check below mentioned solution. You need to call parent constructor first. So it will load all basic configurations.
First extent CI_Controller class and call parent constructor like describe below
class MY_Controller extends CI_Controller {
public function __construct{
parent::__construct();
}
}
Please let me if it not works.

Why does my code end with: Call to a member function sample_template() on null

I am using hierarchical MVC model in codeigniter. I create a controller called template and inside it a function called sample_template. Then a view called sample_template_v created and call it inside the template controller. I create another controller called Admin and called Template->sample_template($data); inside its 2 funtions.
MY_Controlle.php
<?php
class MY_Controller extends MX_Controller
{
function __construct()
{
parent::__construct();
$this->load->module('Template');
}
}
Admin.php
<?php
class Admin extends MY_Controller
{
function __construct()
{
parent::__construct();
}
function index()
{
$data['content_view'] = 'admin/admin_v';
$this->Template->sample_template($data);
}
function about()
{
$data['content_view'] = 'admin/about_v';
$this->Template->sample_template($data);
}
}
Template.php
<?php
class Template extends MY_Controller
{
function __construct()
{
parent::__construct();
}
function sample_template($data = NULL)
{
$this->load->view('Template/sample_template_v', $data);
}
}
sample_template_v.php file---->
<h5>This is the main Template.</h5>
<?php $this->load->view($content_view); ?>
Error:
If you want to call a method from the object you need to initiaze the object and then call a method. Make sure $this->template is set in your case it isn't.
$this->template = new Template();
$this->template->sample_template($data);

CodeIgniter load database in Controller or Model?

Model :
class Users_model extends CI_Model {
function __construct() {
parent::__construct();
$this->load->database();
}
public function get_all_users() {
return $this->db->get('users');
}
}
Controller :
class Users extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->helper('form');
$this->load->helper('url');
$this->load->helper('security');
$this->load->model('Users_model');
}
public function index() {
redirect('users/view_users');
}
public function view_users() {
$data['query'] = $this->Users_model->get_all_users();
$this->load->view('users/view_all_users', $data);
}
}
My question is where should i put the $this->load->database? In Model or Constructor? If possible tell me why?
And one more question, if i omit the $this->load->database, the error shown
"Undefined property: Users::$db". I'm expecting "Undefined property:
Users_model::$db".
Why is that? Is it looking for $db in both controller or model?
Thank you.
Note: i can connect to database just fine. What im actually ask is if i want to use $this->load->database(). Where should i put it? Controller or Model? And why?
You can either load the database in the controller or you can load it in the model.There's not much of a difference its just more neat and clean that all the interaction in the database is in the model and the controllers the one who connects both views and model.The controller here is like a middleman between the buyer and the seller.
load database in the controller
<?php
class Test_controller extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->database('default');
$this->load->model('test_model');
}
public function index()
{
$this->db->from('test');
$query = $this->db->get();
echo "<title>CodeIgniter SQlite</title>";
$data['db']=$query->result();
//print_r($data['db']);
$count = count($data['db']);
echo "Row count: $count rows<br>";
for ($i=0; $i < $count; $i++) {
echo $data['db'][$i]->text." ";
}
}
}
?>
load database in the model
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Test_model extends CI_Model
{
public $table1 = 'test';
public $table2 = '';
public function __construct()
{
parent::__construct();
$this->load->database('default');
}
public function check_db()
{
$this->db->from($this->table1);
$query = $this->db->get();
return $query->result();
}
}
Go to autoload.php in application/config/autoload.php and add this
$autoload['libraries'] = array('database'); // add database in array(now you dont need to load database at anywhere in project)
Make database connection settings in database.php, file located atapplication/config/database.php
now try this
class Users_model extends CI_Model {
function __construct() {
parent::__construct();
//$this->load->database(); <----remove this
}
public function get_all_users() {
return $this->db->get('users');
}
}

Class 'CI_Controller' not found in E:\xampp\htdocs\ninja\system\core\CodeIgniter.php

Here is code of mu controller file
<?
if(!defined('BASEPATH')) exit ('not allow a direct access');
class password extends CI_Controller{
public function __construct()
{
parent::__construct();
$this->load->module('layout');
ini_set('display_errors','On');
error_reporting(E_ALL^E_NOTICE);
$this->load->database();
$this->load->helper('text');
}
public function index()
{
//$this->load->model('forgetPassword/forget_mdl');
//$data['package_detail'] = $this->register_mdl->package_detail();
$this->layout->getHeaderLayout('Forget Password');
$this->layout->getTopBarLayout();
$this->layout->getHeaderTopLayout();
$this->blade->render('forgetPassword/forgetPassword_view');
$this->layout->getFooterLayout();
}
}
?>
controller name and file name must match. Also controller name is expected as "Password" not "password"
class Password extends CI_Controller{
