1 entity.module entity_view_mode_prepare($entity_type, $entities, $view_mode, $langcode = NULL)

Invoke hook_entity_view_mode_alter().

If adding a new entity similar to nodes, comments or users, you should invoke this function during the ENTITY_build_content() or ENTITY_view_multiple() phases of rendering to allow other modules to alter the display mode during this phase. This function needs to be called before field_attach_prepare_view() to ensure that the correct content is loaded by field API.

Parameters

$entity_type: The type of entity, i.e. 'node', 'user'.

$entities: The entity objects which are being prepared for view, keyed by object ID.

$view_mode: The original display mode e.g. 'full', 'teaser'...

$langcode: (optional) A language code to be used for rendering. Defaults to the global content language of the current request.

Return value

An associative array with arrays of entities keyed by display mode.:
