Create an install hook to pre-define a list of films to import.
Create a custom Drush command, which makes use of re-usable functions within our Movie Import module.
Create an administration form to save information about how the movie importer works by using variables.
Create a permissions hook to secure access to pages within Drupal.
Learn how to use Features to manage configuration changes and understand the configuration change workflow in a team environment.
Use hooks to update the database tables and alter form elements.

Add user data to the database from an existing form.
Display custom content using a render array.
Render content which can be refreshed via Ajax.
Create a custom block with details from the database containing information about user preferences.
Every Drupal module needs a *.info.yml file; the basic structure of a form controller class and related routing is the same for every form; and much of the code required to create a custom content entity type is boilerplate annotations and extending base classes. Wouldn't it be nice if there was a way to automate some of that repetitive work? Drush can be used to speed up module development by generating scaffolding code for event subscribers, forms, services, module files, routing, and much more. These generators are provided by the Drupal Code Generator project. They're neatly bundled up in Drush under the drush generate
command.
Before Drush 9, there were no code generators in Drush, but the Drupal Console project provided them. That project and its code generators, have languished since the release of Drupal 9. While it can still be used, and is often referenced in tutorials about Drupal, we much prefer the code generated by Drush at this point.
In this tutorial we'll:
- Learn about the Drupal Code Generator project
- Learn how Drush integrates with this project
- Demonstrate the
drush generate
command and its options
By the end of this tutorial, you'll know how to use the drush generate
command to speed up development for your Drupal modules.
Installing Drupal using the instructions in this tutorial will give you a working Drupal site that can be used for learning, or real-world project development.
Before you can work on a Drupal site locally (on your computer), you'll need to set up a local development environment. This includes all the system requirements like PHP and a web server, that Drupal needs in order to run. Our favorite way to accomplish this is using DDEV.
In this tutorial we'll learn:
- How to install and configure DDEV for use with a Drupal project.
- How to use DDEV's integrated Composer to download Drupal and Drush.
- How to install Drupal inside DDEV so you can access the site and start doing development.
By the end of this tutorial, you should be able to set up a local development environment for learning Drupal or working on a new Drupal project.
Standardized documentation is crucial to a project, whether it is just you or an entire team working on it. In this tutorial we're going to look at:
- Standards for
@docblock
comments - Standards for inline comments
- Why standards for documentation and comments are as important as standards for the rest of your code.
By the end of this tutorial you'll know how to add inline documentation for all the PHP code that you write for Drupal.
Formatting standards cover things like the use of whitespace, how to format control structures, and other aspects that affect your code's appearance and format.
In this tutorial we’ll talk specifically about standards regarding formatting. This is by no means an exhaustive list of PHP syntax rules, but rather is focused on formatting standards for Drupal.
By the end of this tutorial you'll know about the most common Drupal code formatting standards as well as where to find more information when questions arise.
