If your module makes use of entity_view(), add the following view-related hooks:
/**
* Act on a {ENTITY} that is being assembled before rendering.
*
* @param ${ENTITY}
* The {ENTITY} entity.
* @param $view_mode
* The view mode the {ENTITY} is rendered in.
* @param $langcode
* The language code used for rendering.
*
* The module may add elements to ${ENTITY}->content prior to rendering. The
* structure of ${ENTITY}->content is a renderable array as expected by
* drupal_render().
*
* @see hook_entity_prepare_view()
* @see hook_entity_view()
*/
function hook_{ENTITY_ID}_view(${ENTITY}, $view_mode, $langcode) {
${ENTITY}->content['my_additional_field'] = array(
'#markup' => $additional_field,
'#weight' => 10,
'#theme' => 'mymodule_my_additional_field',
);
}
/**
* Alter the results of entity_view() for {ENTITY}s.
*
* @param $build
* A renderable array representing the {ENTITY} content.
*
* This hook is called after the content has been assembled in a structured
* array and may be used for doing processing which requires that the complete
* {ENTITY} content structure has been built.
*
* If the module wishes to act on the rendered HTML of the {ENTITY} rather than
* the structured content array, it may use this hook to add a #post_render
* callback. Alternatively, it could also implement hook_preprocess_{ENTITY}().
* See drupal_render() and theme() documentation respectively for details.
*
* @see hook_entity_view_alter()
*/
function hook_{ENTITY_ID}_view_alter($build) {
if ($build['#view_mode'] == 'full' && isset($build['an_additional_field'])) {
// Change its weight.
$build['an_additional_field']['#weight'] = -10;
// Add a #post_render callback to act on the rendered HTML of the entity.
