In Drupal, we use the terminology of entity, and we have bundles inside an entity. As part of the Drupal core functionality, we have content types, which is in fact an entity type and therefore the Post content type is a bundle.
So, now that we are familiar with some basic Drupal terminology, let's move on to creating our Post content type.
If you use the menu at the top and click on Manage | Structure | Content Types, you will be taken to the Admin page for Content types:
Fig 1.1: The content type management page
By default, we have two content types in a standard Drupal installation (Basic page and Article). Article is pretty much a Post content type; however, for this, we shall ignore this and create our own content type entirely from scratch.
To create a new content type, click on + Add content type:
Fig 1.2: The Add content type page
On this page, we are presented with some fields, which we use to set up how a content type works.
So, let's add the information for these fields:
Name: Post
Description: Create a new post to display
Menu settings: Uncheck all available menus
Click on Save and manage fields, and we have now started our Post content type.
The content type is split into four tabs:
Edit: This allows for the settings we just added to be modified; however, you cannot change the machine name once the content type is created.
Manage fields: This allows us to add/edit/remove fields from the content type. In the previous versions of Drupal, you could move the fields up and down to order how they appear on the form. This is no longer the case and appears under the Manage form display tab.
Manage form display: This allows for the fields to be reordered and the formats to be amended for this page. This won't affect the Manage display tab. It will only be visible to any user who has permission to add, edit, or delete.
Manage display: This allows the fields to be reordered for how they will appear on the display. It will affect the output of how the fields are displayed on the page.
