Chapter 5 ■ Content Types • Have the ability to sort content items by specific “fields.” • Have the ability to “filter” or restrict which content items are displayed on a page based on a value in a field. • Enforce the structure of how a piece of content is rendered on a page; for example, you may want to display information about a book and want the title to be followed by the author, followed by the ISBN, followed by the price, followed by the description of the book. While you could publish all of this information in a Basic page or an Article, providing the features for sorting, filtering, making values required, calculating, and structuring how a content item is rendered on a page would be extremely difficult. Fortunately, Drupal’s ability to define custom content types makes all of the above possible, and provides many more features that you will find invaluable over time. Defining a Custom Content Type A custom content type is defined by you, the Drupal administrator, over and above the Basic page and Article content types. The ability to create custom content types is included in Drupal 8 core. To demonstrate the power and flexibility of custom content types, let’s create a new custom content type for capturing information about upcoming events. An event could be a concert, a play, a class, a game, or any other activity that is scheduled in advance. When authoring information about an event, you may want to include the following details: • The name or title of the event • The date and time when the event begins • The date and time when the event ends • The venue or address where the event will be held • A description of the event • The price for attending the event As you will see in a few moments, Drupal provides a simple-to-use administrator’s interface for creating and modifying custom content types. As soon as you define a custom content type, it is immediately available to those users who have the proper privileges to author, edit, publish, and delete that specific content type (Drupal provides the ability to restrict access to custom content types by user role). Creating a Custom Content Type Creating a custom content type takes two basic steps: sitting down and listing the types of information you want to collect, and building the custom content type using Drupal’s custom content type administration screens. For this example, let’s create a custom content type for an event that includes the types of information listed in the previous section. To get started, click the Manage link at the top of the page and the Structure link in the submenu. On the Structure page (shown in Figure 5-1), click “Content types.” 48
Chapter 5 ■ Content Types Figure 5-1. Structure page with “Content types” link The “Content types” screen (shown in Figure 5-2) lists all of the existing content types, which in our case are the Article and Basic page content types that are included with Drupal 8 core. The “Content types” screen also provides a link to create a new content type. Click the “Add content type” button to start the process of creating our Event content type. Figure 5-2.
