I am utterly and completely confused. I've looked through all the documentation and I can't find a solution. Setup: CI 2.1.3, QNAP server.
Problem: I cannot use a private function on a controller:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Signup extends CI_Controller {
public function index()
{
_loadcontent();
}
private function _loadcontent()
{
$this->load->view('welcome_message');
}
}
/* End of file signup.php */
/* Location: ./application/controllers/account/signup.php */
it won't work and gives an HTTP Error 500 (Internal Server Error). HOWEVER, placing the file in the main controller directory works. Does anybody have any clue? is this a bug? Thanks in advance.
You need to call the function using $this.
public function index()
{
$this->_loadcontent();
}

I have a form in a view called login_view that I would like to target a function in the Login controller.
For my form in login_view I have echo form_open('/Login/validate_credentials');
In my Login.php controller I have:
<?php if (! defined('BASEPATH')) exit('No direct script access allowed');
class Login extends CI_Controller{
function __construct()
{
parent::__construct();
}
public function validate_credentials(){
$this->load->view('welcome2');
}
}
?>
When I submit the form from the browser, instead of loading the welcome2 view like I expect, it tries to load the URL of:
localhost/project/Login/validate_credentials
and I just see the default page for WAMP.
It's my first day in Code Igniter so I'm sure the answer is simple.
Just replace your controller construct by this:
public function __construct()
{
parent::__construct();
$this->load->helper(array('url','text','html','form','string'));
}
As I am very pleased of the command show_404() which you can call everywhere to show a 404-Error-Page, I did want to implement a show_403() for requests without permissions.
I created the file application/core/MY_Exceptions.php and added the following code:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class MY_Exceptions extends CI_Exceptions {
public function __construct()
{
parent::__construct();
}
public function show_403($page = '', $log_error = TRUE)
{
//do some stuff
echo "test";
}
}
Then I'll call it in a controller application/controllers/Welcome.php like this:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Welcome extends CI_Controller {
public function index()
{
// show_404(); // <-- this works!
show_403(); // <-- this works not!
}
}
and I keep getting the following error in the browser, when I access the controllers index method:
Fatal error: Call to undefined function show_403()
As you may have noticed I even tested this on a vanilla installation of CodeIgniter, so you should be able to reproduce this error with just these two files.
I know that I could load the extension manually, but that has not the elegance of using show_403() wherever and whenever I want...
Routing is set up correctly, CodeIgniter is version 3.0.3, PHP is version 5.6.12., filesystem permissions to application/core/MY_Exceptions.php have even been set to 777 for debugging purposes.
Your exception class is not loaded, so its giving that error.
Load your class like this
$excep = load_class('Exceptions', 'core', $this->config->item('subclass_prefix'));
echo $excep->show_403();// will echo test
One more suggesion is to use helpers for this,
Add your code in application/helpers with file name error_helper
public function show_403($page = '', $log_error = TRUE)
{
//do some stuff
echo "test";
}
Calling your function
$this->load->helper('error_helper');
echo show_403();
I have tried to create a hyperlink to another page using anchors however it doesn't seem to work.
My function is called calendar and its stored in calcontrol.php within a controllers directory.
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Calendar extends CI_Controller{
public function __construct()
{
parent::__construct();
$this->load->helper('url');
}
public function index()
{
$this->load->view('calendar');
}
}
?>
I have tried other methods but they do not seem to work.
edit : this is my a href
Link
Filename and classname must be the same, otherwise CI will not be able to load it. And if using CI 3, make sure your class name and filename are both Ucfirst. If you have everything set up like this, then you should be able to view the page through http://yourdomain.com/calendar/calendar
Try this code. You forgot to load url helper. File Calendar.php - nogice capital C if CI3:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Calendar extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper('url');
}
public function index()
{
$this->load->view('calendar');
}
}
I was using codeigniter 2.2.1. And now codeigniter 3 released. I just tried it and ended up with error.
When I try to load method as in codeigniter2.x, it shows
Unable to locate the model you have specified: Demo
where Demo is my method file.
Controller - welcome.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Welcome extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('demo');
}
public function index() {
$data = $this -> demo ->check();
print_r($data);
}
}
Model - demo.php
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Demo extends CI_Model {
public function __construct() {
$this->load->database();
}
}
I can't figure-out what is wrong with this code. Please help. Thank you in advance..
Edit:- This is works well in my wamp machine. But I am checking it now in another local machine where my institute host the websites. There it is not working
It was a small issue. I changed model name from demo.php to Demo.php. And it works...
I am new to coding and have fallen in love with codeigniter and recently moved from a wamp server to a LAMP server. I've extracted codeigniter into /var/www/ and set the root directory of the host in apache. I can see the codeigniter welcome page, however if I change the default controller in config.php to my controller and load this controller:
class Site extends CI_Controller {
public function index() {
$this->load->view('home_view');
}
}
I get this text in my browser:
$this -> load -> view ('home_view'); }}
The only line of my index function as well as a codeigniter generated 404 error below it.
base_url() and default controller are set, codeigniter welcome page works fine, but my page does not.
Does anyone have an idea as to why? Your help is very much appreciated.
Make sure your controller is inside application/controllers and the name is site.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Site extends CI_Controller {
public function __construct()
{
parent::__construct();
}
public function index()
{
$this->load->view('home_view');
}
}
