Drupal 8.x

Hello

My name is Silvia, a Spanish girl, and I currently have a site who is hosted on Wordpress. The website is http://el-mejor.com (el-mejor.com)

I love new challenges and Im looking for the best CMS that currently exists. I have heard that Drupal is undoubtedly the best of all because it allows you to develop practically anything that you can think.

Drupal 8:

I am altering a view using hook_views_data_alter to display a date range filter.
I was able to create the form to look the way I wanted with hook_form_alter.

It looks like this:

Start Date: (textfield, the value of which is a filter)
End Date: (textfield, the value of which is a filter)

Now, this works and it filters successfully. What I'm having a hard time with, though, is a pair of radio buttons I'm generating in hook_form_alter.

Hello Gurus,
I have a REST Export view display setup in Drupal 8, showing node fields. It's AWESOME.

The challenge: I want to theme/tweak/alter the output of JSON or HAL_JSON. Currently, it's rendering this in JSON:

Is it possible to use the nice datepicker that the Form API has in views? If so, how might one go about doing so?

I'm creating a hierarchy. Let's say:

- Library
-- Section
--- Book
---- Page

Each level is a different content type, and each level should only be able to point up to the level above.

There seem to be two ways of doing this:

This must be incredibly simple, but I'm having a difficult time understanding how form submission works in Drupal 8.

I have created a form that extends FormBase. I have a controller that is calling that form with
$form = \Drupal::formBuilder()->getForm($form_path);
and then I just return the form.
