我想指出，我并不是真正的开发人员，而是设计师。我正在尝试在 Wordpress 模板文件中添加自定义联系表单。它的工作原理基于Cats Who Code: How to create an built-in contact form for your Wordpress theme 中的教程。
我已将联系表格修改为以下内容：
- 名称（文本字段）
- 公司（文本字段）
- 地址（文本区域）
- 电子邮件地址（文本字段）
- 电话（文本字段）
- 移动（文本字段）
- 查询（文本区）
但是，当我将它集成到自定义模板中并将其放在 Wordpress 安装中时，它只会给我一个空白页面，其中包含空白代码。我想知道为什么会发生这种情况，当我从模板中删除联系表时，没有联系表一切都很好。下面是整个模板代码。

我试图弄清楚它在哪里崩溃，但我对 PHP 不是很了解，也无法理解它。谁能指出我哪里出错了，将不胜感激。
