Drupal 以编程方式修改缺少hostEntity字段的字段集合

我试图修改已存在的节点中的字段集合，以便可以更改3个数组中第一个元素的图像。问题是，当我执行实体加载或实体加载时未设置hostEntity信息，因此当我执行以下操作时：

$field_collection_item->save(true); // with or without the true
// OR
$fc_wrapper->save(true); // with or without the true

我得到以下错误：

Exception: Unable to save a field collection item without a valid reference to a host entity. in FieldCollectionItemEntity->save()

打印字段集合实体时，hostEntity:protected字段确实为空。我的字段集合设置如下：

  // $node: (obj) node object returned from node_load()
  // $collection: (string) can be found in drupal admin interface: 
  //              structure > field collections > field name
  // $fields: (array) see usage below
  // $index: (int) the index to the element you wish to edit           
  
  function updateFieldCollection($node, $collection, $fields = Array(), $index = 0) {
      if ($node && $collection && !empty($fields)) {
          // Get the field collection ID
          $eid = $node->{$collection}[LANGUAGE_NONE][$index]['value'];
  
          // Load the field collection with the ID from above
          $entity = entity_load_single('field_collection_item', array($eid));
  
          // Wrap the loaded field collection which makes setting/getting much easier
          $node_wrapper = entity_metadata_wrapper('field_collection_item', $entity);
  
          // Loop through our fields and set the values
          foreach ($fields as $field => $data) {
              $node_wrapper->{$field}->set($data);
          }
  
          // Once we have added all the values we wish to change then we need to 
          // save. This will modify the node and does not require node_save() so
          // at this point be sure it is all correct as this will save directly
          // to a published node 
          $node_wrapper->save(true);
      }
  }
  

  用法：

  // id of the node you wish to modify
  $node = node_load(123); 
  
  // Call our function with the node to modify, the field collection machine name
  // and an array setup as collection_field_name => value_you_want_to_set
  // collection_field_name can be found in the admin interface:
  // structure > field collections > manage fields
  updateFieldCollection(
      $node,
      'field_home_experts',
      array (
          'field_expert_image' => (array)file_load(582), // Loads up an existing image
          'field_expert_name' => 'Some Guy',
          'field_expert_title' => 'Some Title',
      )
  );
  

  希望这对其他人有帮助，因为我花了一整天的时间试图让它发挥作用（希望我在Drupal7不会永远是个傻瓜）。正确设置格式化文本可能会有问题，但我现在不确定这是什么，所以请记住这一点（例如，如果您有一个格式为filtered_html的字段，则不确定在不执行其他操作的情况下是否会正确设置）
  祝你好运！

  好吧，我想我已经解决了这个问题，我编写了一个函数，可以设置字段集合值：

          // Load the field collection with the ID from above
          $entity = entity_load_single('field_collection_item', array($eid));
  
          // Wrap the loaded field collection which makes setting/getting much easier

  在使用上述函数后，我仍然得到问题中提到的错误。 这就是我的工作原理：

  function updateFieldCollection($node, $collection, $fields = Array(), $index = 0) {
    $eid = $node->{$collection}[LANGUAGE_NONE][$index]['value'];
    $fc_item = entity_load('field_collection_item', array($eid));
    foreach ($fields as $field => $data) {
      $fc_item[$eid]->{$field}[LANGUAGE_NONE][0]['value'] = $data;
    }
    $fc_item[$eid]->save(TRUE);
  }

  我希望这对其他人有所帮助，因为我花了相当长的时间才使其正常工作。
