There are some key points that you need to understand though. A seasoned PHP developer wont find it that difficult to develop with Drupal. How hard this will be for you, is also highly dependent on your background. You might be able to find some good videos, but you will only really master this when you get your hands dirty and start coding. If you encounter any issues, get in touch with me in the comments section below.It requires some effort to learn how to develop in Drupal. Although this is a very simple Drupal module, it essentially covers all the basics of creating a Drupal 8 module. That’s it! You’ve successfully created your very first custom Drupal 8 module. Check again and it should function properly this time. If you get the ‘Page Not Found’ error, then clear the cache by navigating to admin->configuration->performance. To check if it functions properly, visit the path you specified in your routing file. Login to your Drupal site and enable your module, if you haven’t done it already. In this file enter the following code: 'Hello World!', In my case, I’ll give it the name HelloWorldController.php. Make sure that the name is relatable so that it’s easily identified. We will now create a controller file which essentially controls the functionality of your module. Create a folder named src under your module’s root directory, then create a new folder under src with the name Controller. All external plugins, controllers etc are placed under this directory. Next, we will need to create a new subdirectory under our module’s folder which will hold the controller file. _permission: 'access content' - (The permissions required for the module to successfully perform its function) ![]() _controller: Drupal\hello_world\Controller\HelloWorldController::hello - (the namespace and the method that the controller will call) Inside this file, the following code will be placed: hello_world: This file will be used by the controller to know at which URL path the module’s function will execute. Now we will create a routing file for the module. Type: module - (Declaring that this is a module) Package: Custom - (Declaring that this is a custom module) Inside this file, we will include details of the module so that Drupal can identify it: name: Hello World (The name to be displayed on the modules list in Drupal)ĭescription: First Custom Drupal 8 Module (Description of the module to be displayed) So I’ll create a yaml file like this hello_. For Drupal to be able recognize the module, we have to create a yaml file with the machine name of our module. info files have been replaced to yaml files with the extension. So in order to do this, create a new directory under the sites directory as shown.Ĭreate a folder in this directory with the machine name of your module. ![]() Although you can place this new module directly in the Drupal root’s module directory, it is always better to place it in sites/all/modules folder in order to be able to differentiate between Drupal’s core modules and our custom modules. We will need to create a new directory in Drupal where we’ll place our module. The machine name that I’ll give it to is hello_world. Since we all started programming using the famous Hello World, I’ll be naming our first custom module hello world as well.
