Question

我在Drupal 8中有多个值图像字段，我想在Controller中为树枝模板中的输出准备值。

这很简单（好吧，如果我们可以称之为非常复杂的＆＃34;让我们在OOP中做所有事情 - 尽管它是无用的＆＃34; Drupal 8简单的方法）单值字段：

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

$data = array();
foreach ($nodes as $node) {
  $data[] = array(
    'rocnik' => $node->get('field_rok')->getValue(),
    'miesto' => $node->get('field_miesto_konania')->getValue(),
    'fotografie' => $node->get('field_zbornik')->getValue(),
    'foto' => $node->get('field_fotografie')->getValue(),
  );
}

return array(
  '#theme' => 'riadky_zazili',
  '#data' => $data,
  '#title' => 'Zažili sme',
);

但是，field_fotografie值是多个值字段，我想在$data数组中获取所有图像的URI。有人知道吗？理想情况下，不到10行无用的OOP jibber-jabber。感谢。

Answer 1

尝试这样，它可能对你有用。

$data = array();
foreach($nodes as $node) {
  $photo = array();
  foreach($node->get('field_image')->getValue() as $file){
    $fid = $file['target_id']; // get file fid;
    $photo[] = \Drupal\file\Entity\File::load($fid)->getFileUri();
  }

  $data[] = array(
    'rocnik' => $node->get('field_rok')->getValue(),
    'miesto' => $node->get('field_miesto_konania')->getValue(),
    'fotografie' => $node->get('field_zbornik')->getValue(),
    'foto' => $photo,
  );
}

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

$data = array();
foreach ($nodes as $node) {
  $fotoValues = $node->get('field_fotografie')->getValue();
  $myvalues  = array();
  foreach($fotoValues as $val){
    $myvalues[] = $val["value"];
  }
  $data[] = array(
    'rocnik' => $node->get('field_rok')->getValue(),
    'miesto' => $node->get('field_miesto_konania')->getValue(),
    'fotografie' => $node->get('field_zbornik')->getValue(),
    'foto' => $myvalues,
  );
}

return array(
  '#theme' => 'riadky_zazili',
  '#data' => $data,
  '#title' => 'Zažili sme',
);

希望这会对你有所帮助感谢
