Working with Content Once again, our primary means of communicating with <strong>Drupal</strong> is through large structured arrays that define all the information we need. In this case, our $return array has a single entry, artwork. The string artwork, as the top-most key, will serve as the "machine name" of this entity, which is how it will be referred to in code. The label key specifies what name should be shown to the user. The base table, revision table, and object keys entries tell the entity system about how our artwork is going to be stored, and are used by the default controller: • The main table where artworks are stored is called artwork, which has a primary key field (the "id" field) of aid. • Revisions will be stored in a table called artwork_revision, and the revision's unique ID is called vid. • Since we're supporting multiple bundles, we also tell the system what field will indicate to which bundle a given artwork belongs. In this case, we use the type field. • The human-readable name of a given artwork is stored in the title field. The view modes key defines the different ways that our entity can be viewed. In this case we are defining a "full" version and a "teaser" version, just as nodes use, but we could define whatever view modes we wanted. Other modules are free to inject additional view modes via hook_entity_info_alter() as well. As usual, the key of the view modes array is the machine name of the view mode and the label property is the human-friendly name. The custom settings flag indicates whether or not the Field UI should allow field formatters to be configured separately for that view mode by default. It is easily changed via the UI. We also define a uri_callback function, namely artwork_uri(). That allows us to abstract out the definition of the path within <strong>Drupal</strong> where this artwork will be accessed. Instead of hard coding a path, such as artwork/$aid, we call a callback function to generate it for us. That is most important when listing entities of different types, as we can simply call a single function, entity_uri($type, $entity), and get back the correct information to pass to the url() or l() functions. Our simple callback looks like this: function artwork_uri($artwork) { return array( 'path' => 'artwork/' . $artwork->aid, ); } [ 158 ]
