Magento – Magento2: How to create different home page

I think the best answer to this question currently looks like this (using price as example attribute):

/** @var  \Magento\Catalog\Model\ProductFactory */
protected $productFactory;

/** @var  \Magento\Catalog\Model\ResourceModel\Product */
protected $productResourceModel;

public function __construct(
    \Magento\Catalog\Model\ProductFactory $productFactory,
    \Magento\Catalog\Model\ResourceModel\Product $productResourceModel
)
{
    $this->productFactory = $productFactory;
    $this->productResourceModel = $productResourceModel;
}


private function setStoreViewPrice($productId, $storeId, $price)
{
    $product = $this->productFactory->create();
    $this->productResourceModel->load($product, $productId);
    $product->setStoreId($storeId);
    $product->setPrice($price);
    $this->productResourceModel->saveAttribute($product, 'price');
}

You can achieve this by building a custom module. So our first step is to create a module folder and the necessary files required to register a Magento module.

1. Create the following folders:

   app/code/YourCompany
app/code/YourCompany/YourModule

The YourCompany folder is the module’s namespace, and YourModule is the module’s name.

Note: If you don’t have the code folder in your app directory, create it manually.

2. Now that we have a module folder, we need to create a module.xml file in the app/code/YourCompany/YourModule/etc folder with the following code:

    <?xml version="1.0"?>
    <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="YourCompany_YourModule" setup_version="1.0.0">
    </module>
    </config>  
   
   

3. To register the module, create a registration.php file in the app/code/YourCompany/YourModule folder with the following code:

<?php   
\Magento\Framework\Component\ComponentRegistrar::register(   
    \Magento\Framework\Component\ComponentRegistrar::MODULE,   
    'YourCompany_YourModule',   
    __DIR__   
); 

4. Open your terminal and go to the Magento 2 root. Run from there the following command:

php bin/magento setup:upgrade

If you want to make sure that the module is installed, you can go to Admin → Stores → Configuration → Advanced → Advanced and check that the module is present in the list or you can open app/etc/config.php and check the array for the ‘YourCompany_YourModule’ key, whose value should be set to 1.

Creating a controller

1. First we need to define the router. To do this, create a routes.xml file in the app/code/YourCompany/YourModule/etc/frontend folder with the following code:

<?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="yourmodule" frontName="yourmodule">   
            <module name="YourCompany_YourModule" />   
        </route>   
    </router>   
</config>

Here we’re defining our frontend router and route with an id “yourmodule”.

The frontName attribute is going to be the first part of our URL.

In Magento 2 URL’s are constructed this way: <frontName>/<controler_folder_name>/<controller_class_name>

So in our example, the final URL will look like this:

yourmodule/index/index

2. Now we create the Index.php controller file in the app/code/YourCompany/YourModule/Controller/Index folder with the following code:

<?php   
 
namespace YourCompany\YourModule\Controller\Index;   
 
use Magento\Framework\App\Action\Context;   
 
class Index extends \Magento\Framework\App\Action\Action   
{   
    protected $_resultPageFactory;
  
    public function __construct(Context $context, \Magento\Framework\View\Result\PageFactory $resultPageFactory)   
    {   
        $this->_resultPageFactory = $resultPageFactory;   
        parent::__construct($context);   
    }   
 
    public function execute()   
    {   
        $resultPage = $this->_resultPageFactory->create();   
        return $resultPage;   
    }   
}

In Magento 1 each controller can have multiple actions, but in Magento 2 this is not the case. In Magento 2 every action has its own class which implements the execute() method.

Creating a block

We'll create a simple block class with the getHelloWorldTxt() method which returns the “Hello world” string.

1. Create a Helloworld.php file in the app/code/YourCompany/YourModule/Block folder with the following code:

<?php   
namespace YourCompany\YourModule\Block;

class Helloworld extends \Magento\Framework\View\Element\Template
{   
    public function getHelloWorldTxt()   
    {   
        return 'Hello world!';   
    }   
}   

Creating a layout and template files

In Magento 2, layout files and templates are placed in the view folder inside your module. Inside the view folder, we can have three subfolders: adminhtml, base and frontend. The adminhtml folder is used for admin, the frontend folder is used for frontend and the base folder is used for both, admin and frontend files.

1. First we will create a yourmodule_index_index.xml file in the app/code/YourCompany/YourModule/view/frontend/layout folder with the following code:

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../../lib/internal/Magento/Framework/View/Layout/etc/page_configuration.xsd" layout="1column">   
    <body>   
        <referenceContainer name="content">   
            <block class="YourCompany\YourModule\Block\Helloworld" name="helloworld" template="helloworld.phtml" />   
        </referenceContainer>   
    </body>   
</page>  

Every page has a layout hand and for our controller action the layout handle is yourmodule_index_index. You can create a layout configuration file for every layout handle.

In our layout file we have added a block to the content container and set the template of our block to helloworld.phtml, which we will create in the next step.

2. Create a helloworld.phtml file in the app/code/Inchoo/Helloworld/view/frontend/templates folder with the following code:

<h1><?php echo $this->getHelloWorldTxt(); ?></h1>

$this variable is refrencing our block class and we are calling the method getHelloWorldTxt() which is returning the string ‘Hello world!’.

And that’s it. Open the /yourmodule/index/index URL in your browser
