I have a custom entity and i don't have any fields in the entity.Instead what i have is:- Adding custom entity page has a form where we have several fields where we are able to fill all the fields in the form.Now the problem which i m facing is is: how to display the entity added on my_entity/% page?

  • check if this module helps you. – arpitr Sep 30 '13 at 11:31

if you are using Entity API, you can take a look to this article http://www.trellon.com/content/blog/creating-own-entities-entity-api and to the example_task module:

The process works like this:

  // Your entity view path
  $task_uri = 'task/%example_task';
  $task_uri_argument_position = 1;

  $items[$task_uri] = array(
    'title callback' => 'entity_label',
    'title arguments' => array('example_task', $task_uri_argument_position),
    'page callback' => 'example_task_view',
    'page arguments' => array($task_uri_argument_position),
    'access callback' => 'entity_access',
    'access arguments' => array('view', 'example_task', $task_uri_argument_position),
    'file' => 'example_task.pages.inc',

 * Task view callback.
function example_task_view($task) {
  drupal_set_title(entity_label('example_task', $task));
  return entity_view('example_task', array(entity_id('example_task', $task) => $task), 'full');

This will invoke to the function in entity/includes/entity.controller.inc folder of Entity API module:

   * Implements EntityAPIControllerInterface.
  public function view($entities, $view_mode = 'full', $langcode = NULL, $page = NULL) {
    // For Field API and entity_prepare_view, the entities have to be keyed by
    // (numeric) id.
    $entities = entity_key_array_by_property($entities, $this->idKey);
    if (!empty($this->entityInfo['fieldable'])) {
      field_attach_prepare_view($this->entityType, $entities, $view_mode);
    entity_prepare_view($this->entityType, $entities);
    $langcode = isset($langcode) ? $langcode : $GLOBALS['language_content']->language;

    $view = array();
    foreach ($entities as $entity) {
      $build = entity_build_content($this->entityType, $entity, $view_mode, $langcode);
      $build += array(
        // If the entity type provides an implementation, use this instead the
        // generic one.
        // @see template_preprocess_entity()
        '#theme' => 'entity',
        '#entity_type' => $this->entityType,
        '#entity' => $entity,
        '#view_mode' => $view_mode,
        '#language' => $langcode,
        '#page' => $page,
      // Allow modules to modify the structured entity.
      drupal_alter(array($this->entityType . '_view', 'entity_view'), $build, $this->entityType);
      $key = isset($entity->{$this->idKey}) ? $entity->{$this->idKey} : NULL;
      $view[$this->entityType][$key] = $build;
    return $view;

As you can see the content is finally rendered through a render element using "Entity.tpl.php"

A way to add your customizations to the view in order to render elements which are not fields may be extending from "EntityAPIController" and writing builContent function:

class ExampleTaskController extends EntityAPIController {

      public function buildContent($entity, $view_mode = 'full', $langcode = NULL, $content = array()) {
        $wrapper = entity_metadata_wrapper('example_task', $entity);
        $content['author'] = array('#markup' => t('Created by: !author', array('!author' => $wrapper->uid->name->value(array('sanitize' => TRUE)))));

        // Make Description and Status themed like default fields.
        $content['description'] = array(
          '#theme' => 'field',
          '#weight' => 0,
          '#title' =>t('Description'),
          '#access' => TRUE,
          '#label_display' => 'above',
          '#view_mode' => 'full',
          '#language' => LANGUAGE_NONE,
          '#field_name' => 'field_fake_description',
          '#field_type' => 'text',
          '#entity_type' => 'example_task',
          '#bundle' => $entity->type,
          '#items' => array(array('value' => $entity->description)),
          '#formatter' => 'text_default',
          0 => array('#markup' => check_plain($entity->description))

        return parent::buildContent($entity, $view_mode, $langcode, $content);
  • i don't have fields in the entity. i have fields in form. how to render entity.? – neetu morwani Sep 30 '13 at 11:34

    I have edited the answer. I think what you are looking for is extending builContent function in roder to show your custom info which is not a drupal field. Hope this helps – Enxebre Sep 30 '13 at 11:50
