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);
}
}

It is working perfectly fine on my local server but when I upload the code to my hosting its throwing this error.
Please, tell me what the problem is. After receiving the input field from the Glade file and attempting to use it, a segmentation error is caused.
namespace MyApp {
class MyAppClass : Object {
Entry myAppEntry;
public MyAppClass () {
Builder builder = new Builder.from_file("myApp.ui");
myAppEntry = builder.get_object("myAppEntry") as Entry;
}
public void button_click(){
stdout.write(myAppEntry.get_text().data); //There is a segmentation error
}
}
}
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

public function __construct() {
parent::__construct();
$this->load->model('configuracion_m', 'Configuracion_m');
}
function todos() {
return $this->Configuracion_m->get_all();
}
Thanx!!!!!

When application starts, this error come up
In the MainView.xaml, you defined the AutoWireViewModel property to true. Once this property is set to True, the ViewModelLocator will try to instantiate the corresponding ViewModel based on a particular convention. Since the names of your View and ViewModel met the convention, when you set this property to true, Prism will help you instantiate the corresponding ViewModel.
Inside Prism.mvvm namespace, the ViewModelLocationProvider class locates the view model for the view that has the AutoWireViewModelChangedattached property set to true. And the error is thrown by the following code line of ViewModelLocationProvider class:
/// <summary>
/// The default view model factory which provides the ViewModel type as a parameter.
/// </summary>
static Func<Type, object> _defaultViewModelFactory = type => Activator.CreateInstance(type);
System.MissingMethodException: 'No parameterless constructor defined for this object.'
So it is caused by the Activator.CreateInstance(Type) method requires a public constructor, please see MissingMethodException.
If I add a parameterless constructor it works normal.
It seems like this is the correct solution. If you just don't want a parameterless constructor for the ViewModel, you may try instantiate it and set the DataContext to the View by yourself. If you doubt this is an issue for Prism library maybe you can open a thread here.
Update:
According to #rubStackOverflow, it was missing ViewModelLocationProvider.SetDefaultViewModelFactory((viewModelType) => Container.GetInstance(viewModelType)); on OnInitializeAsync method.
Hi am trying to add custom helper throughout my application
Have done following steps
index.php
$view = new Zend_View();
$view->addHelperPath('My/View/Helper', 'My_View_Helper');
Zend_Controller_Action_HelperBroker::addHelper($viewRenderer);
Helper class in My/View/Helper
class My_View_Helper_Common extends Zend_View_Helper_Abstract
{
public function example()
{
return "ok";
}
}
now calling in view index.phtml
$this->example()
am getting this error
Uncaught exception 'Zend_View_Exception' with message 'script 'error/error.phtml' not found in path (.\application\views\scripts\)' in C:\xampp\htdocs\wyfixture\library\Zend\View\Abstract.php:924

please help me
In addition to Vikas answer.
To call more than one method in a view helper you can use code like this:
In My/View/Helper/Example.php
class My_View_Helper_Example extends Zend_View_Helper_Abstract
{
public function example()
{
return $this;
}
public function foo()
{
return 'foo';
}
public function bar()
{
return 'bar';
}
public function __toString()
{
return $this->foo();
}
}
In you views:
echo $this->example()->foo() // prints foo
echo $this->example()->bar() // prints bar
echo $this->example() // prints foo
Seems like you have two problems here:
Your 'application/views/scripts/error/error.phtml' is missing. You can restore it and you'll get more accurate exception message at once.
Your helper class should contain a method named after the helper.
So, in your case it's file My/View/Helper/Example.php with the following body
class My_View_Helper_Example extends Zend_View_Helper_Abstract {
public function example() {...}
}
Then you'll be able to call it from the view with
$this->example()
