Correct way to use Drupal 7 Entities and Field API
- by Martin Petts
I'm trying to use Drupal 7's entities and field API to correctly build a new module. What I have been unable to understand from the documentation is the correct way to use the new API to create a 'content type' (not a node type) with a number of set fields, such as Body.
I'm trying to set up the entity using hook_entity_info, then I believe I need to add the body field using field_create_instance, but I can't seem to get it to work.
In mycontenttype.module:
/**
* Implements hook_entity_info().
*/
function mycontenttype_entity_info() {
$return = array(
'mycontenttype' => array(
'label' => t('My Content Type'),
'controller class' => 'MyContentTypeEntityController',
'base table' => 'content_type',
'uri callback' => 'content_type_uri',
'entity keys' => array(
'id' => 'cid',
'label' => 'title'
),
'bundles' => array(
'mycontenttype' => array(
'label' => 'My Content Type',
'admin' => array(
'path' => 'admin/contenttype',
'access arguments' => array('administer contenttype')
)
)
),
'fieldable' => true
)
);
return $return;
}
/**
* Implements hook_field_extra_fields().
*/
function mycontenttype_field_extra_fields() {
$return['mycontenttype']['mycontenttype'] = array(
'form' = array(
'body' = array(
'label' = 'Body',
'description' = t('Body content'),
'weight' = 0,
),
),
);
return $return;
}
Then does this go in the .install file?
function mycontenttype_install() {
$field = array(
'field_name' => 'body',
'type' => 'text_with_summary',
'entity_types' => array('survey'),
'translatable' => TRUE,
);
field_create_field($field);
$instance = array(
'entity_type' => 'mycontenttype',
'field_name' => 'body',
'bundle' => 'mycontenttype',
'label' => 'Body',
'widget_type' => 'text_textarea_with_summary',
'settings' => array('display_summary' => TRUE),
'display' => array(
'default' => array(
'label' => 'hidden',
'type' => 'text_default',
),
'teaser' => array(
'label' => 'hidden',
'type' => 'text_summary_or_trimmed',
)
)
);
field_create_instance($instance);
}
