Drupal 8エンティティフォームのファイル拡張子を検証する

Drupal 8という名前のエンティティがvisual_tracker_entityにあります。これが私のエンティティです。

ファイルタイプフィールドの検証ルールを追加する必要があります。デフォルトのファイルタイプには.txt拡張子が付いています。 .xls.xlsxのみを許可します。これはfileファイルです

  $fields['my_new_file'] = BaseFieldDefinition::create('file')
          ->setLabel(t('My New File'))
          ->setDescription(t('The name of the Visaul tracker entity entity.'))
          ->setDefaultValue('')
          ->setDisplayOptions('view', array(
            'label' => 'above',
            'type' => 'file',
            'weight' => -4,
          ))
          ->setDisplayOptions('form', array(
            'type' => 'file',
            'weight' => -4,
          ))
          ->setDisplayConfigurable('form', TRUE)
          ->setDisplayConfigurable('view', TRUE);

私を助けてください。

ファイルフィールドを使用している場合は、「file_extensions」設定を設定できます。 「ファイル」タイプの詳細については、 FileItem APIページに移動するか、IDEで検索してください。クラスの注釈は、制約を追加する必要がある場合に、制約システムなどについて学ぶのに役立ちます。

 $fields['my_new_file'] = BaseFieldDefinition::create('file')
   ->setSetting('file_extensions', 'xls xlsx');

これとは別に、ファイルのアップロードがあるDrupal 8フォームを作成する場合は、次の方法でアップロードバリデーターを渡すことができます。

$validators = array(
  'file_validate_extensions' => array('csv'),
  'file_validate_size' => array(file_upload_max_size()),
);
$form['csv']['csv_file'] = array(
  '#type' => 'file',
  '#title' => $this->t('CSV File'),
  '#description' => array(
    '#theme' => 'file_upload_help',
    '#description' => $this->t('The CSV file must include columns in the following order:'),
    '#upload_validators' => $validators,
  ),
  '#upload_validators' => $validators,
);

...次に、validateFormの実行中にこれらの拡張機能を検証します。

public function validateForm(array &$form, FormStateInterface $form_state) {
  $this->file = file_save_upload('csv_file', $form['csv']['csv_file']['#upload_validators'], FALSE, 0);

  // Ensure we have the file uploaded.
  if (!$this->file) {
    $form_state->setErrorByName('csv_file', $this->t('File to import not found.'));
  }
}
