To develop a custom module. Basically, Magento 2 custom modules are available in the app/code directory with the format of app/code/VendorName/ModuleName.
How to create simple module steps are shown below:
- Directory for the module
- Configuration for the module
- Registration for the module
- Front-end router file
- Controller file
- Block file
- Front-end layout file
- Front-end template file
- Install setup and Enable module
Directory for the module
To create a simple module, we need to set up the structure of the module. So, Let’s now create folders in app/code.
vendor name: namespace name
Helloworld(Folder name ) : module name
Controller: Controls the flow of the module action
Block: Contains the PHP file of the module
etc: Configuration-related file of the module.
etc/frontend: front-end router file will be available here.
view/frontend/layout: frontend layout (XML) file will be available here.
view/frontend/template : frontend template (.phtml) file.
Configuration for the module
First of all, Create a module.xml file in app/code/Module/Helloworld/etc And paste the below code :
Registration of Module
After that, Registration of the module is must be required. So, create registration.php file in app/code/Module/Helloworld/ and paste the below code :
Front-end router file
Then, the front-end router file is used to set the front page’s router name to access at the front side. So, create routes.xml file in app/code/Module/Helloworld/etc/frontend and paste the below code
Controller file
The controller file is used for executing the action of the module. So, create an Index.php file in app/code/Module/Helloworld/Controller/Index and paste the below code :
Front-end layout file
This file is frontend layout file. Create helloworld_index_index.xml file in app/code/Module/Helloworld/view/frontend/layout and paste the below code :
Front-end template file
Now, create helloworld.phtml file in app/code/Module/Helloworld/view/frontend/templates which is used to call block function and also some designing codes
Install setup and Enable module
Now, all things of the module are ready. So, it’s time for the setup module. To set up the module first time, we need to execute the below command :
php bin/magento setup:upgrade
For check the module status :php bin/magento module:enable RH_Helloworld
At last, clean and flush cache :php bin/magento cache:cleanphp bin/magento cache:flush
