Renttek_VirtualControllers

Enables creating of routes with "virtual controllers"

What is a virtual controllers? A virtual controller is a path + an optional layout handle which will be set. With that it is possible to create custom routes where you can place custom blocks to your wishes. (In Magento 2 this is currently only possible by creating a route.xml & a dummy controller action, which returns a \Magento\Framework\View\Result\Page)

Comparison

Here is a short comparison of the minimal required code to create a custom route (example/page/view) in Magento 2 (given there is already a module My_Module)

Vanilla Magento 2

<module_dir>/etc/frontend/routes.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
    <router id="standard">
        <route id="example" frontName="example">
            <module name="My_Module"/>
        </route>
    </router>
</config>

<module_dir>/Controllers/Page/View.php

<?php

namespace Mapa\Content\Controller\Page;

use Magento\Framework\App\Action\Action;
use Magento\Framework\App\Action\Context;
use Magento\Framework\View\Result\PageFactory;

class View extends Action
{   
    private $resultPageFactory;
    
    public function __construct(Context $context, PageFactory $resultPageFactory)
    {
        parent::__construct($context);
        $this->resultPageFactory = $resultPageFactory;
    }

    public function execute()
    {
        return $this->resultPageFactory->create();
    }
}

With this Module

<module_dir>/etc/virtual_controllers.xml

<?xml version="1.0"?>
<controllers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="urn:magento:module:Renttek_VirtualControllers:etc/virtual_controllers.xsd">
    <controller path="example/page/view" />
</controllers>

Features

Handles

Besides the much simpler creation of custom routes, every route will get a few layout handles set:

• "default"
• "virtual_controller"
• The given path, but all characters except [a-z_] are replaced by underscores. (example/page/view => example_page_view)

The generated handle can also be set manually in the xml configuration like this:

<module_dir>/etc/virtual_controllers.xml

<?xml version="1.0"?>
<controllers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="urn:magento:module:Renttek_VirtualControllers:etc/virtual_controllers.xsd">
    <controller path="example/page/view" handle="my_custom" />
</controllers>

Routes can also be disabled by setting disabled=true in the configuration:

<?xml version="1.0"?>
<controllers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="urn:magento:module:Renttek_VirtualControllers:etc/virtual_controllers.xsd">
    <controller path="example/page/view" disabled="true" />
</controllers>

Forwards

Another feature is the possibility of creating forwards without creating a controller. Forwards are needed if you want to display another URL for a page. (e.g. 'my/shoppingcart' => 'checkout/cart')

<?xml version="1.0"?>
<controllers xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="urn:magento:module:Renttek_VirtualControllers:etc/virtual_controllers.xsd">
    
    <forward path="my/shoppingcart"
             module="checkout"
             controller="cart"
             action="index"/>
</controllers>

In V1 the attributes controller and action defaulted to 'index' if not specified. In V2 this is not the case!

Forwards are only URLs/path that CAN be called. It does not extend/manipulate url generation in any way.

All routes are merged by the path attribute, so it is possible to disable routes from other modules.
