I am having issues with my Code Ignitor, in that I load my model the code fails, without leaving any trace.
I am attempting to load my model like so
<!--CONTROLLER-->
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Concierge extends Public_Controller {
public function submit()
{
$this->load->model('Concierge_model');
}
My model is set up as below:
<!--MODEL-->
<?php
class Concierge_model extends CI_Model {
public function __construct()
{
parent::__construct();
}
function saveRequest($action, $owner)
{
$query = $this->db->query('select * from table');
return $query;
}
Does anyone see what might be the issue that is causing my problem? I am using CodeIgnitor 2.1.2.
Assuming Public_Controller is something custom, make sure that class extends CI_Controller and also make sure the parent's contruct function is called there.
class Public_Controller extends CI_Controller {
public function __construct() {
parent::__construct();
}
}
I don't know what the problem was, I deleted the model, view, and controller and recreated them. This fixed the issue, but sadly didn't shed any light onto what caused it.

I have old urls like http://example.com/products.php?s_productid=231 and now in my proyect whit url would be http://example.com/products/ver/231
How can I make a rule in routes.php to redirect?
Thanks
you don't need to do any change in routes.php, all you need is to create a Controller "Product", with one Method "ver", which receives 231 (it's id I guess) as a parameter, like this:
defined('BASEPATH') OR exit('No direct script access allowed');
class Product extends CI_Controller {
public function __construct(){
parent::__construct();
}
public function ver($id) {
// do your things
}
I hope it helps.
You may need to set the routes in config/routes.php
$route['product/ver/(:num)'] = 'product/ver/$1';
http://example.com/index.php/products/ver/231
Then the controller
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Product extends CI_Controller {
public function __construct(){
parent::__construct();
}
public function ver($id) {
/*
echo $id;
*/
}
I have a problem in login application in codeigniter , the problem is like this:
I create MY_Controller, like this:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Controller extends CI_Controller {
public function __construct(){
parent::__construct();
}
}
Then I extended it on my library that i created, this is my "Petugas_Controller" library:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Petugas_Controller extends MY_Controller {
public function __construct(){
parent::__construct();
$this->load->model('petugas_m');
} // end contructor.
public function check(){
if ($this->uri->uri_string() !== 'index' && ! $this->petugas_m->is_logged_in() == TRUE){
redirect('admin/petugas/index');
}
}
}
I'm using that library to be used in my "Petugas" controller, like this:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Petugas extends MY_Controller {
public function __construct(){
parent::__construct();
$this->load->library('petugas_controller');
$CI = &get_instance();
$CI->check();
}
public function index(){
echo "You have to login";
}
public function dashboard(){
echo "Welcome to dashboard";
}
}
In "Petugas_Controller" library, I loaded model that is called "Petugas_m", here is the model :
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Petugas_m extends CI_Model {
public function __construct(){
parent::__construct();
}
public function is_logged_in(){
return FALSE;
}
}
That's all what i was trying, and my problem is I want to check if username is logged or not, by doing $this->check() in "Petugas_library" that loads "Petugas_m" model, i could see an dashboard echo if the "check" method in "Petugas_m" is set to TRUE but it's always redirect me a loop if it FALSE.
I was searching for tutorials and still have this crazy problem :( ,
Thank in advance, and sorry for my bad english.
As long as your petugas_controller library is located within the libraries folder, you can access the check method via
$this->petugas_controller->check();
Also try changing the if statement in your check to something more like this
if ($this->uri->uri_string() !== 'index' && $this->petugas_m->is_logged_in() !== TRUE){
lol, I've just realized my mistake here, I've just tried to make another controller, it's called login, then in my "petugas_controller" library I redirect the user if not login to this "login" controller, it's totally worked ...
Youy guys are inspiring me so much,Thanks :)
we have two controllers one is members.php which is registering the user another one is reserv.php for reserving a ticket for busses.
I want to load second controller after completion of first controller class.
members.php
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class Members1 extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('member_model1');
}
public function index() {
$table = $this->member_model1->insert_members();
$data['members'] = $table;
//$this->load->view('header1', $data);
$this->load->view('reservation_view',$data);
//$this->load->view('members');
//$this->load->view('footer');
}
}
reserv.php
<?php
class reserve extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('member_model1');
}
function index() {
$table = $this->member_model1->get_members();
$data['members'] = $table;
//$this->load->view('header1', $data);
$this->load->view('reservation_view',$data);
//$this->load->view('reservation_view');
// $this->load->helper(array('form'));
//$this->load->view('reservation_view');
}
}
?>
To call a controller from another controller, you can use the function redirect() :
// In Members1 controller
redirect('/reserve/index');
Note that you won't be able to send data along with the redirect, such as when you load a view. To send data, you must use $this->session->set_flashdata(); because the redirects seem to use header() (I advise you to have a loot at this post).
// In Members1 controller
$this->session->set_flashdata('key', 'value');
redirect('/reserve/index');
By the way, when I look at your two classes, I wonder why you don't simply create a unique Ticket class with two methods like registerUser() and bookTicket() (these names are pure fancy, be free to use yours).
As I have read through articles, the best possible way to validate a user in all controllers of my application is to extend my own Controller that extends CI_Controller
But I can't make it work.
What I have is a members_controller that extends my MY_Controller.
in MY_Controller i have this piece of code, just to test if how am I going to utilize this.
<?php
class MY_Controller extends CI_Controller {
private $foo;
function __construct() {
parent::__construct();
$this->foo = 'hello world again';
}
}
in my members controller
<?php
class Members extends MY_Controller {
function index() {
$this->load->view('members');
}
}
in my members view
i want to access this variable i just set up, but i don't know how.
i tried echoing it out like this echo $foo, like this $this->foo
but neither work. thanks much!!
You need to pass the variable to your view file.
<?php
class Members extends MY_Controller {
function index() {
$data = array('foo' => $this->foo)
$this->load->view('members', $data);
}
}
Now you can refer to $foo inside your view. You may need to declare $this->foo as protected.
There's a video tutorial on MY_Controller that you may find useful at http://codeigniter.tv/a-10/Extending-the-core-MY_Controller-and-beyond
Have you tried passing the variable to the 'members view'.
$this->load->view('members',$foo);
You need to make $foo as protected and not private.
Then you will be able to access it in your controller that extends MY_Controller.php like this:
$this->foo
Today for the first time I used codeigniter 3. In the past I used version 2.x a lot of times. Now I can't extend CI_Controller:
application/core/MY_Controller.php
class MY_Controller extends CI_Controller {
private $data = array();
function __construct() {
parent::__construct();
date_default_timezone_set("Europe/Zagreb");
$this->data['foo'] = "bar";
}
application/controllers/Welcome.php
class Welcome extends MY_Controller {
public function index() {
$this->data['main_content'] = 'home';
$this->load->view('template/template', $this->data);
}
application/view/home.php
(this is view loaded by $this->data['main_content'])
If I try to echo any data declared in MY_Controller, I get an error.
<?php echo $foo; ?>
A PHP ERROR WAS ENCOUNTERED
Severity: Notice
Message: Undefined variable: foo
Filename: template/header.php
i'm using codeigniter for my project and i have this class model which i call Genesis which looks like this:
class Genesis_model extends CI_Model {
function __construct() {
parent::__construct();
}
function get() {
return 'human soul';
}
}
and i have another model, stored in the same directory, which extends Genesis_model
class Human_model extends Genesis_model {
function __construct() {
parent::__construct();
}
function get_human() {
return $this->get();
}
}
Human_model is used by Human controller
class Human extends CI_Controller {
function __construct(){
parent::__construct();
$this->load->model('human_model');
}
function get_human() {
$data['human'] = $this->human_model->get_human();
$this->load->view('human/human_interface', $data);
}
}
if i execute the code, it will produce an error which point to return $this->get(). it reads "Fatal error: Class 'Genesis_model' not found in ...\application\models\human_model.php on line 2".
i use this method because nearly all my models shared almost identical structure. I gather the similar functionality in Genesis while the other models serve only as data suppliers unique to the tables they represent. it works well in my asp.net (vb.net) but i don't how to do it in codeigniter.
is there a way for Human_model to inherit Genesis_model. i don't think i'm allowed to use include('genesis_model.php'). i don't know if it works either.
thanks in advance.
core/MY_Model is good if there's only 1 important superclass for your models.
If you want to inherit from more than model superclass, a better option is to change your autoload configuration.
In application/config/autoload.php, add this line:
$autoload['model'] = array('genesis_model');
Put the file genesis_model.php in the core directory
Change your Human_model to this:
include('genesis_model.php');
class Human_model extends Genesis_model {
function __construct() {
parent::__construct();
}
function get_human() {
return parent::get();
}
}
notice the get_human function and the include.
You have to include the Genesis_model on your Human_model.php like this:
include_once( APPPATH . 'folder/file' . EXT );
Or you can autoload it on your config/autoload.php file, what I think is stupid =)
other solution
<?php
$obj = &get_instance();
$obj->load->model('parentModel');
class childModel extends parentModel{
public function __construct(){
parent::__construct();
}
public function get(){
return 'child';
}
}
?>
