There are following below steps need to follow to create custom controller in Magento 2.
We are creating Custom Module for Custom Controller.
Step [1] – Create registration.php file under your module [ Namespace / ModuleName ]
File Path=Mage2db/John/registration.php
Add below content in this file.
<?php
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Mage2db_John',
__DIR__
);Step [2] – Create module.xml file under your module [ Namespace / ModuleName ]
File Path=Mage2db/John/etc/module.xml
Add below content in this file.
<?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="Mage2db_John" setup_version="1.0.0" />
</config>Steps [3] – Create routes.xml file under your module etc directory. Add below content in this file.
File Path=Mage2db\John\etc\frontend\routes.xml
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
<router id="standard">
<route id="john" frontName="john">
<module name="Mage2db_John" />
</route>
</router>
</config>Step [4] – Create Controller Index.php file under your module Controller Index directory. Add below content in this file.
File Path=Mage2db/John/Controller/Index/Index.php
<?php
namespace Mage2db\John\Controller\Index;
class Index extends \Magento\Framework\App\Action\Action
{
public function execute()
{
echo 'Hello Mage2DB Magento 2 Learning & Knowledge & Troubleshooting';
exit();
}
}All storefront controllers have to contain a public execute method. It is called when accessing the controller.
The storefront controllers are inherited from \Magento\Framework\App\Action\Action class.
Magento 2 Standard, use of the echo & exit () is totally prohibited here we have used only for Testing Purpose.
Step [5] – Finally your custom controller has been created
Run the following below commands at your Magento 2 root directory
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy -f
php bin/magento indexer:reindex
php bin/magento cache:clean
php bin/magento cache:flushRun below URL
https://mage2db.com/john/index/indexChange https://mage2db.com to your Base URL, Output as below
