Yii2: Stand alone Action in Module

votes

I want to create a directory tree like this:

  • models
  • modules
    • help
      • controllers
        • default
          • IndexAction.php
        • DefaultController.php
      • views
        • default
          • index.php
      • help.php

So that if I call localhost/mysite/web/index.php?r=help/default/index I should get the index view.

So I created a module withe gii. My Module Class is "app\modules\help\help". I had to use help twice so that I get my module in a subdirectory. ( This is something I don't get. Why doesn't create Yii an subdirectory for each module?)

In the next step I created my Stand Alone Action 

<?php
namespace app\modules\help\controllers;

use yii\base\Action;

class IndexAction extends Action
{

    public function run()
    {
        $this->controller->render('index');
    }

}

In the next step I modified my Controller to use the stand alone action

<?php

namespace app\modules\help\controllers;

use yii\web\Controller;

class DefaultController extends Controller
{

    public function actions()
    {
        return [
            'index'    => 'app\modules\help\controllers\default\IndexAction',
        ];
    }

}

If I call now my view in the browser I get the following error:

Unknown Class – yii\base\UnknownClassException
Unable to find 'app\modules\help\controllers\default\IndexAction' in file: E:\wamp\www\my_website/modules/help/controllers/default/IndexAction.php. Namespace missing?

But if I go to this Path E:\wamp\www\my_website/modules/help/controllers/default/ on my pc I get shown the IndexAction.php Can someone help me?

The stand alone action is in a subdirectory of controllers. So the namespace schould be 

namespace app\modules\help\controllers\default;

But that causes this error:

 PHP Parse Error – yii\base\ErrorException
 syntax error, unexpected 'default' (T_DEFAULT), expecting identifier (T_STRING)

EDIT

If I use this namespace app\modules\help\controllers\IndexAction in the IndexAction.php I get the following Error. Even if I change the route in the controller I get the unknownClassException:

Unknown Class – yii\base\UnknownClassException
Unable to find 'app\modules\help\controllers\default\IndexAction' in file: E:\wamp\www\my_website/modules/help/controllers/default/IndexAction.php. Namespace missing?

And if I use this namespace app\modules\help\controllers\default in the IndexAction.php I get this:

 PHP Parse Error – yii\base\ErrorException
 syntax error, unexpected 'default' (T_DEFAULT), expecting identifier (T_STRING)

Have you tried app\modules\help\controllers\IndexAction ? or changing the action's namespace to app\modules\help\controllers\default - Pomme.Verte
Answer is shown in the ticker above in the EDIT statement - EvilKarter
The second part of your edit is the correct way. The error comes from the fact that default is a reserved keyword (part of the switch statement). If you changed it (and folder name) to something else it should work. - Pomme.Verte
You are right. It works if I rename default to index. - EvilKarter

As D.Mill says in his comment. default is a reserved keyword. I had to rename the directory and it now works quite fine.

You are using wrong namespacing replace your code with something like this (note backslash)

    public function actions()
    {
        return [
            'index'    => '\app\modules\help\controllers\default\IndexAction',
        ];
    }
