我有一个用于我构建的 Concrete5 的自定义块，它使用与其关联的多个模板文件。如果我在最初将块添加到页面时将模板应用于块，则一切正常。但是，如果我在设置块之后尝试更改模板，我会遇到问题。使用新模板保存更改时，我的所有内容都会从数据库中删除；因此，当前行中的所有内容都等于 null，除了块 id“bID”，bID 将更改为下一个增量。
我不知道为什么会这样！！我觉得我很久以前遇到过类似的情况，但不记得它是如何解决的。任何建议都会很棒！
我的模板文件只是 php 文件中的标准 html，文件<?php defined('C5_EXECUTE') or die("Access Denied."); ?>顶部有 。
我的控制器（这是我现在对这个问题的怀疑）如下所示：

我提前为相当长的文件道歉；）我只是想确保你能看到所有可能的问题
