Drupal Up - Pal up with drupal

Custom form with our Fibonacci service

We are going to create a custom form that is going to have just a text field and a submit button. The idea is that after entering how many Fibonacci numbers we want to generate we are going to click on submit and as a message we are going to see the generated numbers.

In order to achieve that we are going to use Dependency Injection to inject our Fibonacci service and we are going to call it on form submit.

Here is the video on how we created the Fibonacci service: https://youtu.be/1jmOnnCjMT0

Drupal Up is a platform for learning Drupal ...

The idea is though not just to be another platform with some boring videos but all the videos to be inspired by real-world problems. That means something that you will most probably need if you work with Drupal. We want you to be successful and we want to teach you everything we know about Drupal!
So watch the videos, try to follow and reproduce, ask questions and you will see you will be able to conquer this wonderful sea that Drupal 8 is.
