function entity_example_basic_view

Menu callback to display an entity.

As we load the entity for display, we're responsible for invoking a number of hooks in their proper order.

function entity_example_basic_view($entity, $view_mode = 'tweaky') {
    // Our entity type, for convenience.
    $entity_type = 'entity_example_basic';
    // Start setting up the content.
    $entity->content = array(
        '#view_mode' => $view_mode,
    );
    // Build fields content - this is where the Field API really comes in to play.
    // The task has very little code here because it all gets taken care of by
    // field module.
    // field_attach_prepare_view() lets the fields load any data they need
    // before viewing.
    field_attach_prepare_view($entity_type, array(
        $entity->basic_id => $entity,
    ), $view_mode);
    // We call entity_prepare_view() so it can invoke hook_entity_prepare_view()
    // for us.
    entity_prepare_view($entity_type, array(
        $entity->basic_id => $entity,
    ));
    // Now field_attach_view() generates the content for the fields.
    $entity->content += field_attach_view($entity_type, $entity, $view_mode);
    // OK, Field API done, now we can set up some of our own data.
    $entity->content['created'] = array(

    // hook_entity_view(), so let's get that.
