Show how to manage non-field node attributes with "manage display"

Hmm.. The "manage display" page has javascripty ordering capabilities... You may be talking about more than ordering, but that's definitely in theme-land. But if you're talking about ordering, D7 has it all covered. D6 does too, if I remember. However, in Examples we cover only core examples, so don't cover CCK.

So if I understand your question right, D7 does it all out of the box. And Field example explains how to make a custom field.

Here's the "Manage Display" page

I think what she's asking is how a module can automatically add the fields instead of user adds fields. It is easy and intuitive for users to add fields in D7, just like your example, but I think she's asking to eliminate the need for the user to do that.

As for the support aspect of not covering contrib modules here, this probably be would outside the scope of this area.

Commerce has lots of examples of adding fields programmatically.

But the Node Example here does it. It creates a node type and then adds fields to it.

See below:

So you're talking about adding to "manage display" something which is *not* a field, then? I just looked and the nodeapi_example, which does something like what you're talking about (adding a rating element to a node type) also fails to get the rating into the "manage display".

I think the most likely technique would be to go with a field...

Taxonomy terms are now fields. So yes... the node example and the field example.

Could you possibly use a dependency on the module Viewfield whereas your field is actually a view and the view is gathering your badges as images? So if a user has a badge it is grabbed by the viewfield and if not then the field is not displayed.

On a sidenote, I was about to start a D7 site where it would be heavily reliant on user badges in a social type setting (like GetGlue) so I'm glad you mentioned this, Nancy. I haven't even started looking into the available user badge modules so good to know they aren't up yet. I can help with this module if you would like since I will be needing it myself shortly. Just let me know.

If I've understood what you are requesting correctly, the hook you are looking for in D7 is hook_field_extra_fields:

An example of this would be:

function mymodule_field_extra_fields() {
  $entity_type = 'node';
  $bundle = 'page';
  $field_id = 'test';
  $extras = array();
  $extras[$entity_type][$bundle]['display'][$field_id] = array(
    'label' => 'Test Fake Field', 
    'description' => 'Adds a fake field to the manage display', 
    'weight' => 10,
  );
  return $extras;
}

You can then use the following to render what your fake field does:

function mymodule_entity_view($entity, $type, $view_mode, $langcode) {
  /// following code poached from eva.module, this gets the various different settings
  /// applied to your fake field by way of the display mode UI.
  $entity_data = entity_get_info($type);
  $entity_ids = entity_extract_ids($type, $entity);
  $settings = field_view_mode_settings($type, $entity_ids[2]);
  $fields = field_extra_fields_get_display($type, $entity_ids[2], $view_mode);
  /// then added my own rendering code if my fake field exists...
  $field = 'test';
  if ( isset($fields[$field]) ) {
    $entity->content[$field] = array(
      '#markup' => 'This is a test',
      '#weight' => $fields[$field]['weight'],
    );
  }
}

For inspiration and examples look to the eva module, I was rather overly happy when I found this -- my task went from something near impossible, to very simple. Thank you D7 :)

Entity Example shows how to implement hook_field_extra_fields(): http://api.drupal.org/api/examples/entity_example%21entity_example.modul...

Node Example shows how to add fields programmatically, in node_example_node_type_insert(). I'd link to it, but the api.d.o site hasn't crawled it yet.

Marking this as closed but please re-open if we're missing something.
