Zend 2 中的 FlashMessenger [英] FlashMessenger in Zend 2

问题描述

我正在做 zend 2 学习.现在我结帐 flashMessenger 助手.似乎没有在 layout.php 中调用 flashMessenger 的记录方法.因为我想在位于布局的 div 中显示所有消息(错误或成功)，所以我需要在那里调用 flashMessenger.我不想每次都通过控制器的动作发送消息，只想要动作只添加消息和布局显示它们.

I am doing zend 2 Study. Now I checkout flashMessenger helper. It seems there are no documented way to call flashMessenger at layout.php. because I want to show all messages (error or success) at div located at layout, I need to call flashMessenger there. I do not want to send messages everytime via controller's actions and just want action only add message and layout show them.

虽然我对自定义帮助程序/库持开放态度，但内置解决方案是最好的.(我在 zend 1 上也没有太多工作，所以我不知道即使使用 zend 1 是否也很容易.)

While I am open to custom helper/libs But builtin solution is the best. ( I do not much work on zend 1 also, So I did not know if it is easily possible with even zend 1. )

我查看了一个帖子 如何在我的布局文件中访问 flashmessenger，在 zend 框架中? 但它有针对 zend 1 的自定义解决方案.所以我在想 zend 1 和 1 中是否都没有内置解决方案2.

I checkout one post How do I access flashmessenger in my layout file, in zend framework? But it have custom solution for zend 1. So I am thinking if zend have no built in solution at all in both 1 & 2.

推荐答案

我刚刚编写了自己的简单视图助手:

i just wrote my own simple viewhelper:

<?php

namespace My\View\Helper;

use Zend\View\Helper\AbstractHelper;

class FlashMessenger extends AbstractHelper
{
    protected static $_flashMessenger;

    public function __invoke($namespace = 'default') {

        if (!self::$_flashMessenger) {

            self::$_flashMessenger = new \Zend\Mvc\Controller\Plugin\FlashMessenger;
        }

        return self::$_flashMessenger->setNamespace($namespace);
    }
}

像这样使用:

<? if ($this->flashMessenger()->hasMessages()): ?>
    <ul>
    <? foreach ($this->flashMessenger()->getMessages() as $message): ?>
        <li><?= $message></li>
    <? endforeach ?>
    </ul>
<? endif ?>
