php - 如何从查询中获取节点

Question

我想从节点类型中获取字段值并对其进行更改。
我有这个代码，我不知道如何使用它：

$query = \Drupal::entityQuery('node')
  ->condition('type', 'article');
$nids = $query->execute();
$nodes = $node_storage->loadMultiple($nids);

Answer 1

EntityQuery输出是一个数组，必须在foreach循环中运行。

$query = \Drupal::entityQuery('node')
  ->condition('type', 'article'),
  ->condition('field_foo', 42); // some condition
$nids = $query->execute();
$nodes = $node_storage->loadMultiple($nids);

foreach ($nodes as $n) {
  echo $n->title->value; 

  // do whatever you would do with a node object (set fields, save, etc.)
  $n->set('title', "this is a test");
  $n->save();
}
