I am new to Magento and I tried this tutorial where I will create a controller for Magento 2. https://www.mageplaza.com/magento-2-module-development/how-to-create-controllers-magento-2.html

My problem is: When I try to go to the http://<yourbrowser>/helloworld or http://<yourbrowser>/helloworld/index/index, it renders a blank page.

I followed everything from the tutorial, just I renamed the /vendorName/moduleName to /custom/helloWorld

Here are the codes: app/code/custom/helloWorld/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 frontName="helloworld" id="helloworld"> <module name="custom_helloWorld"/> </route> </router> </config>

app/code/custom/helloWorld/Controller/Index/Index.php

<?php namespace custom\helloWorld\Controller\Index; class Index extends \Magento\Framework\App\Action\Action { protected $_pageFactory; public function __construct( \Magento\Framework\App\Action\Context $context, \Magento\Framework\View\Result\PageFactory $pageFactory) { $this->_pageFactory = $pageFactory; return parent::__construct($context); } public function execute() { return $this->_pageFactory->create(); //Pagefactory is used to initialize the layout. } }

app/code/custom/helloWorld/view/frontend/layout/helloworld_index_index.xml

<?xml version="1.0"?> <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd"> <referenceContainer name="content"> <block class="custom\helloWorld\Block\Index" name="helloworld_index_index" template="custom_helloWorld::index.phtml" /> </referenceContainer> </page>

app/code/custom/helloWorld/Block/Index.php

<?php namespace custom\helloWorld\Block; class Index extends \Magento\Framework\View\Element\Template { }

app/code/custom/helloWorld/view/frontend/templates/index.phtml

<h2>Welcome to HELLO WORLD PAGE!</h2>

I already tried to flush the cache but same problem occur.

I hope you can help me. Thank you so much in advance!!

UPDATE: So I just copied whatever is in the link: https://www.mageplaza.com/magento-2-module-development/how-to-create-controllers-magento-2.html

And still renders a blank page...

As I can see you start vendor name and module name with small character. Ex: "app/code/custom/helloWorld/Block/Index.php"

But it should be like "app/code/Custom/HelloWorld/Block/Index.php"

Kindly refer below link for create custom module:

  • I changed it to "app/code/Custom/HelloWorld/Block/Index.php". And correct the paths on Block, Controller, etc, view folders. As well as the registration.php. Result when I try to access http://<yourbrowser>/helloworld: 404 Not Found Error. Commented Jun 22, 2020 at 7:24

Update Your helloworld_index_index.xml with this ,

<?xml version="1.0"?> <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd"> <referenceContainer name="content"> <block class="Magento\Framework\View\Element\Template" name="helloworld_index_index" template="custom_helloWorld::index.phtml" /> </referenceContainer> </page>

No need of block file... flush the Cache and Run in Browser it works fine...

First rename your module to Custom/HelloWorld - Module name and name space should be having first letter capital ..Its good practise.

Than change code like below

app/code/Custom/HelloWorld/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 frontName="helloworld" id="helloworld"> <module name="Custom_HelloWorld"/> </route> </router> </config>

app/code/Custom/HelloWorld/Controller/Index/Index.php

<?php namespace Custom\HelloWorld\Controller\Index; class Index extends \Magento\Framework\App\Action\Action { protected $_pageFactory; public function __construct( \Magento\Framework\App\Action\Context $context, \Magento\Framework\View\Result\PageFactory $pageFactory) { $this->_pageFactory = $pageFactory; return parent::__construct($context); } public function execute() { return $this->_pageFactory->create(); //Pagefactory is used to initialize the layout. } }

app/code/Custom/HelloWorld/view/frontend/layout/helloworld_index_index.xml

<?xml version="1.0"?> <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd"> <referenceContainer name="content"> <block class="Custom\HelloWorld\Block\Index" name="helloworld_index_index" template="Custom_HelloWorld::index.phtml" /> </referenceContainer> </page>

app/code/Custom/HelloWorld/Block/Index.php

<?php namespace Mageplaza\HelloWorld\Block; class Custom extends \Magento\Framework\View\Element\Template { }

app/code/Custom/HelloWorld/view/frontend/templates/index.phtml

  • Thank you Parul. Copied all your code, except, I corrected the app/code/Custom/HelloWorld/Block/Index.php namespace and class, I flushed the Magento Cache, and access the /helloworld url. Still 404 Not Found Error occurs. Commented Jun 23, 2020 at 1:35
  • Do run command php bin/magento setup:di:compile and let me know if any problem occurs Commented Jun 23, 2020 at 5:48
