Zend 中的 Flash Messenger 类型

Question

是否可能或我如何为 Zend 中的 FlashMessage 指定类型？

例如

/* This is a "Success" message */
$this -> _helper -> FlashMessenger('You are successfully created a post.'); 

/* This is an "Error" message  */
$this -> _helper -> FlashMessenger('There is an error while creating post.');

/* This is just a "Notification" message */
$this -> _helper -> FlashMessenger('Now you can see your Post');

我认为最好的方法是使用 flashmessenger 命名空间：

/* success message */
$this->_helper->FlashMessenger()->setNamespace('success')->addMessage('Post created!');

/* error message */
$this->_helper->FlashMessenger()->setNamespace('error')->addMessage('You have no permissions');

然后在布局中，您可以将消息添加到每个命名空间：

<?php $flashMessenger = Zend_Controller_Action_HelperBroker::getStaticHelper('FlashMessenger');

<?php if ($flashMessenger->setNamespace('success')->hasMessages()): ?>
    <div class="message success">
    <?php foreach ($flashMessenger->getMessages() as $msg): ?>
        <?php echo $msg ?>
    <?php endforeach; ?>
    </div>
<?php endif; ?>

<?php if ($flashMessenger->setNamespace('error')->hasMessages()): ?>
    <div class="message error">
    <?php foreach ($flashMessenger->getMessages() as $msg): ?>
        <?php echo $msg ?>
    <?php endforeach; ?>
    </div>
<?php endif; ?>

有一次你使用关联数组来做到这一点...我不确定这是否仍然是当前的...

/* This is a "Success" message */
$this -> _helper -> FlashMessenger(array('success' => 'You are successfully created a post.')); 

/* This is an "Error" message  */
$this -> _helper -> FlashMessenger(array('error' => 'There is an error while creating post.'));

/* This is just a "Notification" message */
$this -> _helper -> FlashMessenger(array('notice' => 'Now you can see your Post'));

这是可能的。此博客文章中描述的示例实现：

• Zend Framework：查看助手优先级 Messenger | emanaton

摘录：

class AuthController extends Zend_Controller_Action {
  function loginAction() {
    . . .
    if ($this->_request->isPost()) {
      $formData = $this->_request->getPost();
      if ($this->view->form->isValid($formData)) {
        . . .
      } else {
        $this->view->priorityMessenger('Login failed.', 'error');
      }
    . . .
  }
}

Zend Framework 1.12.x 中 FlashMessenger 的方法签名：

public function addMessage($message, $namespace = null)
public function getMessages($namespace = null)
public function hasMessages($namespace = null)
public function clearMessages($namespace = null)

因此，要设置消息，以下内容将起作用：

/* success message */
$this->_helper->flashMessenger()->addMessage('Post created!', 'success');

/* error message */
$this->_helper->flashMessenger()->addMessage('You have no permissions', 'error');

对于视图，以下内容应该起作用：

<?php $flashMessenger = Zend_Controller_Action_HelperBroker::getStaticHelper('FlashMessenger');

<?php if ($flashMessenger->hasMessages('success')): ?>
    <div class="message success">
    <?php foreach ($flashMessenger->getMessages('success') as $msg): ?>
        <?php echo $msg ?>
    <?php endforeach; ?>
    </div>
<?php endif; ?>

<?php if ($flashMessenger->hasMessages('error')): ?>
    <div class="message error">
    <?php foreach ($flashMessenger->getMessages('error') as $msg): ?>
        <?php echo $msg ?>
    <?php endforeach; ?>
    </div>
<?php endif; ?>
