Content Types, Taxonomy, and Comment Types

One of the more powerful capabilities of Drupal is the ability to create custom content types. Often referred to as a node, we can think of Content types as containers for holding content that has been defined with specific fields, such as a title and a body. However, we are not limited to only those two fields. We can pretty much add as many fields as needed based on how the content itself has been defined.

Something new to Drupal 8 is the Comment field, which can be added to content types, allowing users to comment on the content. Drupal provides this ability out of the box as part of the core with the ability to add Comment types that can have fields of their own. We will look at the default configuration and how to customize comments.

We can also add fields to tag, categorize, or classify content, known as Taxonomy. Categorizing content using various terms allows us to enhance content that can then be attached to content types as a term reference.

To help us master Content types, Comment types, and Taxonomy, we will look at the following:

• Exploring content types
• Managing fields
• Creating custom content types
• Adding fields
• Taxonomy, vocabularies, and terms
• Introduction to Comment types
• Working with form and content display
• Using Drupal Console to generate content

Assumptions

Mastering Drupal 8 assumes that you are already running a local AMP stack and are familiar with installing Drupal using the standard means of downloading, setting up a database, configuring a localhost, and completing the browser-based install. In Chapter 1, Developer Workflow, we walked through quickly installing Drupal using Composer, Drush, and Drupal Console. Before continuing, ensure that you have a working AMP stack and are comfortable working within the command-line interface using a Terminal window.

Exploring Content types

In most cases, our first glimpse of content types comes from the two default Content types that Drupal configures as part of the standard install: Article and Basic page.

We can navigate to Content types by directly entering /admin/structure/types or by using the Administration toolbar and clicking on Manage | Structure | Content types:

The Content types page lists all content types, including their name and description. From this page, we can add, edit, and manage content types along with their respective fields and displays. Currently, our Content types consist of Article and Basic page.

To get a better look at the makeup of a content type, we can view the Basic page content type by selecting the drop-down button and choosing Edit:

The Edit screen defines the configuration of a content type by providing a Name, a Description, and four subsections that handle various settings.

Submission form settings

Submission form settings allow us to define the Title field label, specify whether content can be previewed before saving new nodes, and specify any submission guidelines we want to provide to users:

Preview before submitting

The Preview before submitting option provides two functions:

• Appearance of a Preview button when creating a new node
• Ability to switch between various displays of the content

If we navigate to the Add content page by entering /node/add/page or by using the Admin toolbar and clicking on Manage | Content, selecting Add content and then Basic page, we can create our first Basic page and preview the content in it:

On the Create Basic page screen, we will need to enter the following information:

• Title*: About Us
• Body: Add some default Lorem Ipsum using http://www.lipsum.com/:

With our content added, we can select the Preview button to view our content with the ability to change the View mode of how the content is displayed:

The display modes enabled on each content type will determine what choices are available in the View mode dropdown. For our example, we can switch between the Default and Teaser displays. Once we are done previewing the con...
