zend-framework - 如何在 zend Framework 3 中使用 flash Messenger，因为 zf3 中删除了 View 助手。我找不到任何教程/示例来实现此功能

Question

zf3 flash-messenger 的文档页面中提供了以下代码。我知道我必须发送返回变量来查看，才能显示消息。

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)。但无法成功

AlbumController.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);
}

Answer 1

因此，如果您查看刚刚在 successAction() 上发布的示例，该示例会检查 FlashMessenger 是否有消息，如果有，则会将消息传递到 View 中名为 messages 的变量(根据您的需要命名)。

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 是一个旨在创建基于 session 的消息的插件。你滥用它了。它旨在在您的操作所使用的另一个 View 中显示消息。

在您的示例中，您不需要 FlashMessenger，因为您只需显示同一页面中定义的消息。只需使用将在 View 中使用的数组...
