I have trying to override the email library by doing the following steps:
Create file core/MY_Email.php
In file add code below
<?php
class MY_Email extends CI_Email {
public function __construct()
{
parent::__construct();
}
?>
Load library is normal
$this->load->library('email');
I put a die in the top of my class and it appears to not even be included and just uses the regular system email class. I need to extend it to override _smtp_connect(). I have done this with other classes.
I am using CI 3.0.4. I have tried to trace through the loader class; but cannot figure it out.
Put MY_Email.php in application/libraries
You need to put the file in application/libraries NOT application/core
$this->load->library('email');
Create a new file called MY_Email.php and put it in application/libraries/

i am new to Prestashop and i am trying to override a function of a class inside modules/moduleName/src in my custom module in override folder but it is not working.
The path of original file is: modules/moduleName/src/Adapter/file.php
The path of the changed file is: modules/myModuleName/override/src/Adapter/file.php
Extending the class this way it is not woking, it does not use the function of the the changed file.
class MyFileOverride extends MyFile{
public function myFunction(){
//funtion to be changed
}
}
What is the best way to override this file?
Thank you!
Complicated to do. It's not really possible for me...
Otherwise, we can hijack the thing...
The class of your module should extends the class you want to modify and you should change all the calls of the class you want to modify by a call to your class.
Constantin,
I want to add some code that will run for every controller. Adding the code to CodeIgniter's CI_CONTROLLER class seems unconventional.
Where is the right place to include code you want to run for every controller?
Here is the code:
require_once 'vendor/autoload.php';
$bugsnag = Bugsnag\Client::make("my-secret-key-is-here");
Bugsnag\Handler::register($bugsnag);
These classes both come from a dependency installed with Composer.
I suspect I should create a helper, and include it in application/config/autoload.php. But new to CodeIgniter, so not sure of conventions.
Edit: I am using CodeIgniter 3.1.6.
If you want to execute arbitrary code at different points in CodeIgniter's life cycle, you can use the hooks feature.
Official Documentation:
https://codeigniter.com/user_guide/general/hooks.html
1. Enable hooks
Go to /application/config/config.php.
Search for enable_hooks and set it to true: $config['enable_hooks'] = TRUE;
2. Add desired code to CodeIgniter's hook file:
Go to /application/config/hooks.php.
Choose the desired lifecycle to hook into (see doc link above for a list)
Add code to the lifecycle, e.g. $hook['pre_controller'] = function(){... your code goes here ...}
For this question's example, my hooks.php looks like this:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
// This is the code I added:
$hook['pre_system'] = function(){
require_once 'vendor/autoload.php';
$bugsnag = Bugsnag\Client::make("my-client-key");
Bugsnag\Handler::register($bugsnag);
}
?>
I would just extend the Controller Class.
See "Extending Core Class":
"If all you need to do is add some functionality to an existing library - perhaps add a method or two - then it’s overkill to replace the entire library with your version. In this case it’s better to simply extend the class."
...
"Tip: Any functions in your class that are named identically to the methods in the parent class will be used instead of the native ones (this is known as “method overriding”). This allows you to substantially alter the CodeIgniter core."
class MY_Controller extends CI_Controller {
....
}
Any function you put inside would be added to the core, otherwise, if you use the same name as an existing method, it would replace just that one method.
You'd name it MY_Controller.php and put it inside application/core/, where it's picked up to override CI_Controller automatically.
If you are extending the Controller core class, then be sure to extend your new class in your application controller’s constructors.
class Welcome extends MY_Controller {
public function __construct()
{
parent::__construct();
// Your own constructor code
}
public function index()
{
$this->load->view('welcome_message');
}
}
Looks like you could also use a pre_system or pre_controller hook as described here:
https://www.codeigniter.com/user_guide/general/hooks.html
Assuming it's CodeIgnitor 3.X
Go to application/config/config.php and change:
$config['composer_autoload'] = FALSE;
to
$config['composer_autoload'] = TRUE;
just below the above line include
require_once APPPATH.'vendor/autoload.php';
Or in your controller include
require_once APPPATH.'vendor/autoload.php';
From How to use composer packages in codeigniter?
Go to application/config/config.php and set $config['composer_autoload'] = FALSE; to TRUE:
Enabling this setting will tell CodeIgniter to look for a Composer
package auto-loader script in application/vendor/autoload.php.
As a result you need not to call require_once 'vendor/autoload.php';.
I have to adapt Codeigniter module to Wordpress. It fetches data with SOAP protocol. It needs to use Codeigniter's csrf_protection.
How to include Codeigniter MY_Controller class in Wordpress?
class Balance extends MY_Controller
{
public function __construct()
{
parent::__construct();
$this->config->set_item('csrf_protection', TRUE);
require_once('addons/libraries/nusoap/nusoap.php');
}
...
You need to copy the methods in the nusoap file and try to make like other libraries setup in codeigniter library folder and then :
$this->load->library('nusoap/nusoap')
Nusoap is the class name which is in upper case letter start with and call in controller like above.
Or else you can find / download separate controller codeingiter library file from github
check it and mark accepted if it works!.
Thanks
Hi I have a file called payment.php it contains some functions related to payments and some multiple classess. So I want to include that file in my symfony2 Controller to access its all methods and classless. I am trying it as follows:
//File location is in src/AppBundle/Controller/payment.php
namespace AppBundle\Controller;
require_once __DIR__.'/./payment.php';
//My controller
class ApiServicesController extends Controller
{
$this->payment(array('txnId'=>1112548));
}
But I am not able to access the file and its methods.
I am using this approach because keeping it in /vendor directory it also not able to access because this file contains multiple classless in same files.
Please advice me how can I access this file in my controller.
thanks in advance
If paymant.php have classes you need to make instance of that class to call method from it, that's like basic OOP stuff.
class ApiServicesController extends Controller
{
$this->payment(array('txnId'=>1112548));
}
First of all, where is the method in this controller where you want to call your method? Then, why you are calling payment on $this if it comes from diffrent class. It should be something like this
class ApiServicesController extends Controller
{
public function indexAction()
{
$somePaymentClass = new SomePaymantClass(); //whatever class you want from payment.php
$somePaymentClass->payment(array('txnId'=>1112548));
}
}
But iI strongly recommend to use it as a service and put it in some autoloader namespace.
You have to make a Payment class as a service and then you can use all functions of Payment class in controller. Please refer this document.
http://symfony.com/doc/current/service_container.html
I have created custom controller called "MY_Controller.php" in Application/core, and successfully invoked by inheriting through application controller.
//application/core
class MY_AdminController extends CI_Controller {
function __construct() {
parent::__construct();
}
}
//application/controllers
class User extends MY_AdminController {
public function __construct(){
parent::__construct();
}
}
It works fine. I just changed my file name from "MY_Controller.php" to MY_AdminController.php, and following same class name, but it is throwing following error,
Fatal error: Class 'MY_AdminController' not found
As per the documentation, Whenever you create a class with the MY_ prefix the CodeIgniter Loader class will load this after loading the core library, then why its throwing error...!!!
Go to your config.php and change
$config['subclass_prefix'] = 'MY_'; to $config['subclass_prefix'] = 'MY_Admin';
Expanding on Patel,
the issue is that MY_ is the prefix to the original core files.
Controller, Model, View etc.
MY_ will be used to seek the name of the controller, for example, MY_controller searches for CI_controller.
You cannot load random names using the MY_prefix. you use MY_ to extend the already existing names.
I think the problem is with the class name, you may have not changed the class name from MY_Controller to MY_AdminController
You can use custom classes. But CI only loads the classes with the class prefix in the config file (e.g. MY_). So I explained how it works and created a workaround to load classes automatically. You can find it here https://stackoverflow.com/a/22125436/567854.
Hope this helps :)
If you want to include all the files that are in your core folder. Then write the following code in end of config.php file.Path to file is application/config/config.php
function __autoload($class)
{
if (strpos($class, 'CI_') !== 0)
{
#include_once( APPPATH . 'core/' . $class . EXT );
}
}
By using this you can create multiple classes.
