Wie erstelle ich programmgesteuert eine Entität mit ihren Feldern?

Ich verwende die Entitäts-API, um mit einigen Entitäten zu arbeiten, kann jedoch nicht herausfinden, wie eine neue Entität mit angehängten Feldern erstellt wird. Ich habe ein Bundle erstellt und diesem Bundle einige Felder hinzugefügt. Ich möchte dies tun:

$a = entity_create(...);

ein Array zurückgeben:

isNew => TRUE,
title => '',
attachedField1 => '',
attachedField2 => '',
etc...

Ich möchte dann einfach die Werte aktualisieren und dann entity_save ():

isNew => TRUE,
title => 'Title of my entity',
attachedField1 => 'data for attached field 1',
attachedField2 => 'data for attached field 2',
etc...

Ist das machbar? Wenn das so ist, wie? Es fällt mir schwer, mit Entitäten zu arbeiten.

Hier sind meine Entitätsinformationen:

  $return['k_profile'] = array(
      'label' => t('Profile'),
      'entity class' => 'Entity',
      'controller class' => 'EntityAPIController',
      'base table' => 'k_profile',
      'fieldable' => TRUE,
      'entity keys' => array(
        'id' => 'pid',
        'bundle' => 'type',
        ),
      'bundles' => array(), //added later in hook_entity_info_alter()
      'bundle keys' => array(
        'bundle' => 'type',
        ),
      'label callback' => 'entity_class_label',
      'uri callback' => 'entity_class_uri',
      'access callback' => TRUE,
      'module' => 'k_profile',
    );

Hier ist ein Code, der ein Produkt programmgesteuert erstellt, einschließlich Feldern und Eigenschaften.

/**
 * Create a product programmatically.
 *
 * This is stolen shamelessly from commerce_bpc. However, I'm not comfortable
 * with the field saving using form api. Seems quite odd.
 *
 * @param $product_type
 *   (string) The name of the product type for which products should be created.
 * @param $values
 *   Keyed array with
 *   - 'price' => actual amount owed on this installment; decimal text like '1.50'
 *   - 'amount_paid' => price amount already paid as a decimal text like '1.50';
 *   - 'original_order' => order id of the original order
 *   - 'original_line_item' => line item id of original line item
 *   - 'original_product => product id of the original product from which the
 *     new product is being created.
 * @param $extras
 *   An array for the values of  'extra fields' defined for the product type
 *   entity, or patterns for these. Recognized keys are:
 *   - status
 *   - uid
 *   - sku
 *   - title
 *   Note that the values do NOT come in the form of complex arrays (as they
 *   are not translatable, and can only have single values).
 * @return
 *   The ID of the created product.

function commerce_installments_create_product($product_type, $values, $extras) {
  $form_state = array();
  $form_state['values'] = $values;
  $form = array();
  $form['#parents'] = array();

  // Generate a new product object
  $new_product = commerce_product_new($product_type);

  $new_product->status = $extras['status'];
  $new_product->uid = $extras['uid'];

  $new_product->sku = $extras['sku'];

  // field_original_order[und][0][target_id]
  $order = array(LANGUAGE_NONE => array(0 => array('target_id' => $values['original_order'])));
  $form_state['values']['field_original_order'] = $order;

  field_attach_submit('commerce_product', $new_product, $form, $form_state);

  commerce_product_save($new_product);
  return $new_product->product_id;

Für diejenigen, die ihre Entität mit eck erstellt haben, gibt es hier eine Erklärung: http://drupal.org/node/1377614

einfach gesagt, es sollte reichen zu schreiben

$e = entity_create('type',array());
$e->field_a = ...;
$e->save();

Wenn ich mich nicht irre, macht das Beispiel Node im Examples Project genau das, was Sie wollen.

Model Entities ist das, was Sie brauchen. Es ist ein Starter-Kit für Entitäten. Sie sollten die Modulbeschreibung und die Datei README) lesen, bevor Sie diese installieren.

Es wird mit allem geliefert, was Sie benötigen, damit Sie es tatsächlich so verwenden können, wie es ist. Sie können Felder hinzufügen, Anzeigen verwalten und alles andere.

Verwenden Sie mit dem Contrib Entity API-Modul entity_create zum Beispiel:

try {
  $entity_type = 'entity_type';
  $entity = entity_create($entity_type, array('type' => 'type_or_bundle')); 
  $wrapper = entity_metadata_wrapper($entity_type, $entity);
  $wrapper->type = 'some_type'; // When entity type has bundles, you can specify a type.
  $wrapper->isNew = TRUE;
  $wrapper->title = '';
  $wrapper->attachedField1 = '';
  $wrapper->attachedField2 = '';
  $wrapper->some_other_property = 'foo';
  $wrapper->field_some_field = 'bar';
  $wrapper->field_multiple_field = array('foo', 'bar');
  $wrapper->save();
}
catch (EntityMetadataWrapperException $e) {
  watchdog_exception('my_module', $e); 
}

Siehe auch: Drupal 7 - Erstellen Sie eine Node in Code Seite, die das folgende Beispiel enthält:

function my_create_a_node() {
  global $user;

  // entity_create replaces the procedural steps in the first example of
  // creating a new object $node and setting its 'type' and uid property
  $values = array(
    'type' => 'YOUR_NODE_TYPE',
    'uid' => $user->uid,
    'status' => 1,
    'comment' => 1,
    'promote' => 0,
  );
  $entity = entity_create('node', $values);

  // The entity is now created, but we have not yet simplified use of it.
  // Now create an entity_metadata_wrapper around the new node entity
  // to make getting and setting values easier
  $ewrapper = entity_metadata_wrapper('node', $entity);

  // Using the wrapper, we do not have to worry about telling Drupal
  // what language we are using. The Entity API handles that for us.
  $ewrapper->title->set('YOUR TITLE');

  // Setting the body is a bit different from other properties or fields
  // because the body can have both its complete value and its
  // summary
  $my_body_content = 'A bunch of text about things that interest me';
  $ewrapper->body->set(array('value' => $my_body_content));
  $ewrapper->body->summary->set('Things that interest me');

  // Setting the value of an entity reference field only requires passing
  // the entity id (e.g., nid) of the entity to which you want to refer
  // The nid 15 here is just an example.
  $ref_nid = 15;
  // Note that the entity id (e.g., nid) must be passed as an integer not a
  // string
  $ewrapper->field_my_entity_ref->set(intval($ref_nid));

  // Entity API cannot set date field values so the 'old' method must
  // be used
  $my_date = new DateTime('January 1, 2013');
  $entity->field_my_date[LANGUAGE_NONE][0] = array(
     'value' => date_format($my_date, 'Y-m-d'),
     'timezone' => 'UTC',
     'timezone_db' => 'UTC',
   );

  // Now just save the wrapper and the entity
  // There is some suggestion that the 'true' argument is necessary to
  // the entity save method to circumvent a bug in Entity API. If there is
  // such a bug, it almost certainly will get fixed, so make sure to check.
  $ewrapper->save();
}

So erstellen Sie eine neue Entität mit dem Modul Drupal Core Entity - try Beispiele mit der Contrib Entity API - try Model Entities Modul.
