Codeigniter Class 'REST_Controller' not found

Question

I'm having a problem with the popular REST API codeigniter maintained by Chris Kacerguis.I created a Datadiri controller that looks like this:

<?php
require (APPPATH.'/libraries/REST_Controller.php');

class Datadiri extends REST_Controller{
    function __construct($config = 'rest'){
        parent::__construct($config);
    }
    //tampilkan data
    function index(){
        $buku = $this->db->get('perpustakaan');
        $this->response($buku, 200);
    }
}

This is Rest_controller.php https://github.com/chriskacerguis/codeigniter-restserver/blob/master/application/libraries/REST_Controller.php

But Still same, the error Class 'REST_Controller' not found. how can i solve this?

Fatal error: Class 'REST_Controller' not found in C:\xampp\htdocs\CodeIgniter\application\controllers\datadiri.php on line 4 A PHP Error was encountered

Severity: Error

Message: Class 'REST_Controller' not found

Filename: controllers/datadiri.php

Answer 1

I had the same issue and adding the namespace after the require() statement in the controller solved the problem.

After this:

require (APPPATH.'/libraries/REST_Controller.php');

Add this:

// use namespace
use Restserver\Libraries\REST_Controller;

Answer 2

Finally the problem solved. iam edit application/config/config.php from : $config['subclass_prefix'] = 'MY_'; to : $config['subclass_prefix'] = 'REST_';

And Datadiri.php like this :

<?php
  use Restserver\Libraries\REST_Controller;
   class Datadiri extends REST_Controller{
       function __construct(){
           parent:: __construct();
       }
       function index_get(){
           $buku = $this->db->get('perpustakaan')->result();
           $this->response($buku, 200);
       }
   }

Answer 3

in your controller api php make sure have this,

require APPPATH . '/libraries/REST_Controller.php';
use Restserver\Libraries\REST_Controller;

and then go to your Rest_Controller and make sure you have this

use CI_Controller;
require APPPATH . 'libraries/Format.php';

Hope this help you

Without using Composer.

• Download / extract CI at your project directory
• Download codeigniter-restserver from github (https://github.com/chriskacerguis/codeigniter-restserver)
• Extract codeigniter-restserver over (at the same directory of ) codeigniter, overwritting CodeIgniter files (and dirs) WITH codeigniter-restserver files
• Edit file controllers\api\Example.php Just before line "class Example extends REST_Controller { " add:

require APPPATH . 'libraries/REST_Controller.php'; require APPPATH . 'libraries/Format.php';

After that, it will look like:

... require APPPATH . 'libraries/REST_Controller.php'; require APPPATH . 'libraries/Format.php';

class Example extends REST_Controller {

function __construct()
{

...

For testing: - Open the project in your browser - At the welcome screen, click on REST Server Tests - At the next screen, click on Users (- defaulting to JSON)

Answer 5

I had the same issue while implementing this in my own Codeigniter project. I just copied Format.php and REST_Controller.php files in Libraries Folder.
After placing these files in Libraries Folder, you have to change
namespace Restserver\Libraries;
to
namespace YOUR_PROJECT_NAME\Libraries;
in both files (Format.php and REST_controller.php).
and in your controller which extends REST_Controller put these three lines right after php tag

use YOUR_PROJECT_NAME\Libraries\REST_Controller;
require APPPATH . 'libraries/REST_Controller.php';
require APPPATH . 'libraries/Format.php';

Hope it will help someone. Thanks

Lets try as below....

 <?php
   require('application/libraries/REST_Controller.php');

    class Datadiri extends REST_Controller{
        function __construct($config = 'rest'){
            parent::__construct($config);
        }
        //tampilkan data
        function index(){
            $buku = $this->db->get('perpustakaan');
            $this->response($buku, 200);
        }
    }

OR

Put the REST_Controller.php in application/core then just

<?php

class Datadiri extends REST_Controller{
    function __construct($config = 'rest'){
        parent::__construct($config);
    }
    //tampilkan data
    function index(){
        $buku = $this->db->get('perpustakaan');
        $this->response($buku, 200);
    }
}

Not need to include file placed in core folder.

Answer 7

this library will move into Composer, so you will need to run

composer require chriskacerguis/codeigniter-restserver

and change $config['COMPOSER_AUTOLOAD'] to true in config file

Answer 8

Its a two way reference issue, you can basicly solve it by doing the following two steps:

1-In your api class add the following code at the beginning:

use Restserver\Libraries\REST_Controller;
require APPPATH . 'libraries/REST_Controller.php';
require APPPATH . 'libraries/Format.php';

class Example extends REST_Controller {..

2-In the file : application/libraries/REST_Controller.php add :

use CI_Controller;

before

abstract class REST_Controller extends CI_Controller {

Cheers!

Answer 9

Best way is to install using composer, then load composer autoload file in codeigniter and use namespace use Restserver\Libraries\REST_Controller; in you controller which extends REST_Controller.

Answer 10

add this...

require(APPPATH.'/libraries/REST_Controller.php');
   use Restserver\Libraries\REST_Controller;
   use CI_Controller;
   require APPPATH . 'libraries/Format.php';

Hopefully this will work :)
