I downloaded HMVC files from here and set up my CI 3 installation using these file
Place the MX folder in application/third_party folder
Place the files in application/core MY_Loader & MY_Router
Created a folder module in /application.
Inside module created welcome/controller and welcome/view
In welcome/controller I copied the default welcome controller and in
welcome/view welcome_message.
Then I created a Template Module with and added below code in it
Then I created module for home, here is how my folder structure looks like
class Template extends MY_Controller {
public function __contruct(){
parent:: __contruct();
}
public function core_template($data = null)
{
//$data = new stdClass();
//$data->content = 'home/home_v';
$this->load->view('template/core_template_v', $data);
}
public function dashboard_template($data = '')
{
//$data = new stdClass();
$this->load->view('template/dashboard_template_v', $data);
}
}

$data->content = 'home/home_v';
//$this->slice->view('welcome/welcome', $data);
//print_r($data);
$this->template->core_template($data);
}
}

/* load the MX_Controller class */
require APPPATH."third_party/MX/Controller.php";
class MY_Controller extends MX_Controller {
public function __construct(){
parent::__construct();
$this->load->module('Template');
}
}
I am getting this error:

I try to call a function from a module A to a module B
here is the module A code
namespace A\Epayment\Model;
class Etransactions
{
public function customPayment{
return "test";
}
and module b code
namespace B\Payment\Controller\Index;
class Payment extends \Magento\Framework\App\Action\Action
{
protected $_pageFactory;
protected $_transaction;
public function __construct(
\Magento\Framework\App\Action\Context $context,
\Magento\Framework\View\Result\PageFactory $pageFactory,
\ETransactions\Epayment\Model\Etransactions $transaction
)
{
$this->_pageFactory = $pageFactory;
$this->_transaction = $transaction;
parent::__construct($context);
}
public function execute()
{
echo "Hello World".PHP_EOL;
$foo="a";
echo $foo;
echo $this->_transaction->customPayment();
//echo $this->customPayment();
echo $foo;
exit;
}
}
this code return the "hello world", the first $foo, not the second and doesn't display any error
can someone explain me where is my error ?
EDIT: i didn't change anything but it works fine now.
thanks for the answers anyway
The object you want create the path your are injecting is incorrect.
public function __construct(
\Magento\Framework\App\Action\Context $context,
\Magento\Framework\View\Result\PageFactory $pageFactory,
\A\Epayment\Model\Etransactions $transaction // changes are here
)
{
$this->_pageFactory = $pageFactory;
$this->_transaction = $transaction;
parent::__construct($context);
}
Kindly use exception handling.
try{
$this->_transaction->customPayment();
}catch(Exception $e){
//log your exception here.
}
In Magento, Helper classes are available to use anywhere (Block, Controller, Model, Observer, View). So you should create a method in helper class and call it anywhere by the following way.
Declar the helper class and method: ModuleA\Epayment\Helper\Data.
<?php
namespace ModuleA\Epayment\Helper;
class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
public function yourHelperMethod()
{
# code...
}
}
Call the method:
$helper = $this->_objectManager->create(ModuleA\Epayment\Helper\Data::class);
$helper->yourHelperMethod();
Note: If the object manager is not injected in your class. Please follow the steps below:
1) declare private property:
private $_objectManager;
2) inject in the constructor to initialize:
public function __construct(
\Magento\Framework\ObjectManagerInterface $objectmanager
) {
$this->_objectManager = $objectmanager;
}
3) use in some method:
public function someMethod() {
$helper = $this->_objectManager->create(ModuleA\Epayment\Helper\Data::class);
$helper->yourHelperMethod();
}
i developed an CMS in codeigniter 2 with HMVC and now im trying to migrate to Codeigniter 3. I have the follow issue.
This works in view codeigniter 2
<?PHP $configuracion = $this->load->controller('configuracion/todos');
?>
I recive the error: Fatal error: Cannot redeclare class CI in /home/xxxx/public_html/application/third_party/MX/Base.php on line 57
This is the controller:
<?php
class Configuracion extends MX_Controller {
public function __construct() {
parent::__construct();
$this->load->model('configuracion_m', 'Configuracion_m');
}
function todos() {
return $this->Configuracion_m->get_all();
}
Thanx!!!!!
I have made a service to get Doctrine connection in my models (Not sure if it is a nice approach but I dont want to pass connection from controller to model constructor each time).
So lets say I want products in my controller
public function getProductsAction(Request $request) {
$product_model = new ProductModel();
return $product_model->getProducts();
}
I have Product model Which will access a helper to get "database_connection"
use AppBundle\Helper\ContainerHelper;
class ProductModel {
function getProducts() {
$helper = new ContainerHelper();
$db = $helper->getDoctrine();
$query = "SELECT * FROM customer_products;";
$statement = $db->prepare($query);
$statement->execute();
$result = $statement->fetchAll(PDO::FETCH_ASSOC);
return $result;
}
}
Now this helper is defined in src/AppBundle/Helper/ContainerHelper.php
namespace AppBundle\Helper;
use Symfony\Component\DependencyInjection\ContainerInterface as Container;
class ContainerHelper {
private $container;
public function __construct(Container $container) {
$this->container = $container;
}
public static function getDoctrine() {
$database_connection = $this->container->get('database_connection');
return $database_connection;
}
}
Lets say this service needs "service container" so in app/config/services.yml
services:
app.container_helper:
class: AppBundle\Helper\ContainerHelper
arguments: ['#service_container']
But it gives me error:
Catchable Fatal Error: Argument 1 passed to
AppBundle\Helper\ContainerHelper::__construct() must implement
interface Symfony\Component\DependencyInjection\ContainerInterface,
none given, called in \src\AppBundle\Model\ProductModel.php
on line 148 and defined
While I believe that I have implemented it correctly according to http://symfony.com/doc/current/book/service_container.html and http://anjanasilva.com/blog/injecting-services-in-symfony-2/, its certain that I have missed something or just got the whole bad idea. I need to know if it is a correct concept or what I have missed
While #pavlovich is trying to fix your existing code, I really think you are making this much more convoluted than it has to be. ProductModel itself should be a service with your database connection injected into it.
class ProductModel {
public function __construct($conn) {
$this->conn = $conn;
}
public function getProducts() {
$stmt = $this->conn->executeQuery('SELECT * FROM customer_products');
return $stmt->fetchAll();
}
services:
product_model:
class: AppBundle\...\ProductModel
arguments: ['#database_connection']
// controller.php
$productModel = $this->get('product_model'); // Pull from container
$products = $productModel->getProducts();
Rather than using helpers, I'd recommend using constructor injection and autowiring. It's more safe, future proof and easier to extend and test.
In such case, you'd have to create ProductRepository (more common and standard name for ProductModel) and pass it to controller.
1. Controller
<?php
class SomeController
{
/**
* #var ProductRepository
*/
private $productRepository;
public function __construct(ProductRepository $productRepository)
{
$this->productRepository = $productRepository;
}
public function getProductsAction()
{
return $this->productRepository->getProducts();
}
}
If you have difficulties to register controller as a service, just use Symplify\ControllerAutowire bundle.
2. ProductRepository
// src/AppBundle/Repository/ProductRepository.php
namespace AppBundle\Repository;
class ProductRepository
{
/**
* #var Doctrine\DBAL\Connection
*/
private $connection;
public function __construct(Doctrine\DBAL\Connection $connection)
{
$this->connection = $connection;
}
public function fetchAll()
{
$query = "SELECT * FROM customer_products;";
$statement = $this->connection->prepare($query);
$statement->execute();
return $statement->fetchAll(PDO::FETCH_ASSOC);
}
}
3. Service registration
# app/cofig/servies.yml
services:
product_repository:
class: AppBundle\Repository\ProductRepository
autowire: true
For more you can see similar question with answer here: Symfony 3 - Outsourcing Controller Code into Service Layer
With new version of Symfony 3.3, a new feature is added (Auto-wired Services Dependencies)
https://symfony.com/doc/current/service_container/autowiring.html
https://symfony.com/doc/current/service_container/3.3-di-changes.html
Using this feature, I solved this issue in following way:
Added a new directory /src/AppBundle/Model
Added my model classes in this directory
namespace AppBundle\Modal;
use Doctrine\ORM\EntityManagerInterface;
class ProductModal
{
private $em;
// We need to inject this variables later.
public function __construct(EntityManagerInterface $entityManager)
{
$this->em = $entityManager;
}
// We need to inject this variables later.
public function getProducts()
{
$statement = $this->em->getConnection()->prepare("SELECT * FROM product WHERE 1");
$statement->execute();
$results = $statement->fetchAll();
return $results;
}
}
Added in my app/config/services.yml
AppBundle\Modal\:
resource: '../../src/AppBundle/Modal/*'
public: true
In my controller I can use it like
$products = $this->get(ProductModal::class)->getProducts();
P.S. Dont forget to add use AppBundle\Entity\Product\Product; in controller
I am trying to call model methods from controller. but I am getting Fatal error: Class 'GuestModel' not found in. error
following is the code ::

$this->view->entries = $guestbook->fetchAll();

}
$this->_dbTable = $dbTable;
return $this;
}
}
Zend Framework autoload depends on using the correct directory structure and file naming conventions to find the classes automagically, from the looks of your code my guess would be you're not following it.
I see 2 possible solutions for your problem:
If possible, rename your class to Application_Model_Guestbook, the file to Guestbook.php and make sure to move it to your application/models/ directory. Then you just need to call it in your controller as $guestbook = new Application_Model_Guestbook();. Check this documentation example;
Create your own additional autoloading rules. Check the official documentation regarding Resource Autoloading.
My helper file Acl.php is in library/Helper and I have included it in bootstrap file as below:-
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
protected function _initPlugins()
{
$helper= new Helper_Acl();
// $helper->setRoles();
// $helper->setResources();
// $helper->setPrivilages();
// $helper->setAcl();
}
}
but its giving error, Saying -> Fatal error: Class 'Helper_Acl' not found in Bootstrap.php.
Below is my helper file
class Helper_Acl
{
public $acl;
public function __construct()
{
$this->acl = new Zend_Acl();
}
}
in the bootstrap.php , try this , provided your class is in a Helper folder in the library :
protected function _initHelpers() {
Zend_Controller_Action_HelperBroker::addPrefix("Helper_");
}
if it doesnt work tell me , there are other methods.
You need to add Helper_ to your autoloadernamespaces. Typically, this is done in application/configs/application.ini:
autoloadernamespaces[] = "Helper_"
