zf3 flash-messenger 的文档页面中提供了以下代码。我知道我必须将返回变量发送到查看，以便显示消息。

public function processAction()
{
    // ... do some work ...
    $this->flashMessenger()->addMessage('You are now logged in.');
    return $this->redirect()->toRoute('user-success');
}

public function successAction()
{
    $return = ['success' => true];
    $flashMessenger = $this->flashMessenger();
    if ($flashMessenger->hasMessages()) {
        $return['messages'] = $flashMessenger->getMessages();
    }
    return $return;
}

更新： 我正在尝试将 flash messenger 功能添加到 zf3 的骨架应用程序（专辑库存）中。但无法成功

专辑控制器.php

public function addAction()
{
  $form = new AlbumForm();
  $form->get('submit')->setValue('Add');
  $request = $this->getRequest();

  if ($request->isPost()) {
      $album = new Album();
      $form->setInputFilter($album->getInputFilter());
      $form->setData($request->getPost());
      $add = $request->getPost('submit', 'Cancel');
          if ($form->isValid()) {
              $album->exchangeArray($form->getData());
              $this->table->saveAlbum($album);
              $this->flashMessenger()->addMessage('<div class="alert alert-success" role="alert"><b>Added Successfully...</b></div>');
      } else {
          $this->flashMessenger()->addMessage('<div class="alert alert-danger" role="alert"><b>Failed to Add...!!</b></div>');
      }

      return $this->redirect()->toRoute('album');
  }
  return array('form' => $form);
}

因此，如果您查看刚刚发布的示例，在 上successAction()，示例检查 FlashMessenger 是否有消息，如果有，它会将消息传递给名为messages（根据需要命名）的变量中的视图。

所以在你看来：

<?php if (isset($messages)): ?>
    <ul>
    <?php foreach($messages as $message): ?>
        <li><?= $message ?></li>
    <?php endforeach; ?>
    </ul>
<?php endif; ?>

编辑消息后更新FlashMessenger：是一个插件，旨在创建基于会话的消息。你在滥用它。它旨在在您的操作使用的另一个视图中显示消息。

在您的示例中，您不需要，FlashMessenger因为您只显示在同一页面中定义的消息。只需使用将在视图中使用的数组...
