我想一旦你知道它就很简单，但我现在正在搜索这个主题超过 4 小时。所以也许有人可以帮助我，推动正确的方向。
我用 Extbase 为 TYPO3 6.2 开发了一个扩展。插件配置是使用 FlexForm 完成的。为了提高可用性，我想在我的 FlexForm 中添加工具提示（帮助文本或 CSH）。
方法1： 我用标签尝试过
<cshFile>
并将相应的 XML 添加到扩展文件中。正如许多论坛和博客所建议的那样，这已被弃用，所以我坚持让我们尝试另一种方法。
方法 2： 将“locallang_csh_flexforms.xml”添加到 ext_tables.php 中的插件。这似乎更合乎逻辑，也建议作为新的方法来做到这一点。此方法也以某种方式被 tx_news 扩展使用，该扩展总体上具有可靠的代码。
但是，这似乎对我不起作用，我尝试替换所有已弃用的类（由 tx_news 使用）并将实现克隆到我的插件中。显示了 FlexForm，但仍然没有可用的工具提示。我现在将发布一些我当前状态的代码片段。它试图做“tx_news”中所做的事情。
这些是我最常使用的文件，如果我没有忘记的话。如果还有其他感兴趣的，请告诉我，我会添加它。
tx_news 中的功能
ext_tables.php
if (!defined('TYPO3_MODE')) {
die ('Access denied.');
}
