How to set body field display programmatically on node type install?

Question

When hook_installing a new custom node type filled with custom fields I call field_create_instance($instance) where I also set the custom fields' display like so:

'display' => array(
  'default' => array( // view mode
    'label' => 'hidden',
    'type' => 'text_default'
  ),
  'teaser' => array( // view mode
    'label' => 'hidden',
    'type' => 'hidden'
  )
)

I also added a body field via node_add_body_field($type) but where can I set that body's display properties programmatically? Per default it's set to be displayed in the teaser view. I want to hide it.

Answer 1

If you want to create the body field for the new content type by invoking node_add_body_field(), then your only option is to implement hook_field_create_instance() to modify the display values of the instance.

This doesn't seem very efficient. Since you are creating other field instances programmatically, you might as well also create a body field instance for your new content type by re-using/copying the code of node_add_body_field in your custom function, which will allow you to set the display values to whatever you want.

You can access and alter the view mode configuration via field_bundle_settings(), (which is basically a shortcut to variable_get and variable_set):

$bundle = 'my_node_type';
$bundle_settings = field_bundle_settings('node', $bundle);
$bundle_settings['view_modes']['teaser']['custom_settings'] = true;
field_bundle_settings('node', $bundle, $bundle_settings);
