Drupal 8 Programatically created custom form.

In this video, we are going to create a simple module with a form in it.
We will explain the basic structure that a Drupal 8 basic form should have. In our example, the form would be having two fields and a submit button and after clicking on submit it will simply sum the two fields. We will also create a simple route in order to be able to show the form on its own page.

Very nice and simple tutorial, best for beginners. Rather than confusing beginner developer with lot of code and terminology you have simply explained everything with minimal code possible. After this we can easily create complex forms and add our logic to submit function.

Hi Nikolay, your videos are simple and clear.
One question, is it possible to calculate between the two numbers not while saving but while typing?
Example we add another field called sum. When I type 10 in number_1 I add the value of number_1 and number_2 in sum.
Then if you want you can submit it. In this way you have the result of the work before submitting.
Thank you

Great tutorial. I'm going to create a custom form and assign it into a custom block. I then assign the custom block into a region. Anonymous users can see the form however admin or authenticate users are unable to view the form. What is the reason?
