Forms 如何将Symfony2中表单的日期字段数据和时间字段数据连接起来，以保存为数据库datetime字段中的datetime数据？

我想知道如何在Symfony2中将表单的日期字段数据和时间字段数据连接起来，以保存为数据库datetime字段中的datetime数据。解释如下：

我想在此屏幕截图中向表单添加两个新的时间字段：

这是表单的代码（以twig和html格式）：

这是我与之交易的实体的代码：

问题是，当我运行代码时，表单不会显示，这就是我看到的：

所以我的问题是：我的代码到底出了什么问题？？？。有人知道吗？

在表单模板中，您可以添加两次starttime，而不是一次starttime和一次endtime。除此之外，我不知道您的控制器逻辑。您应该将getStartTime（）的逻辑更改为smth，如下所示：return$this->getStart（）->format（“H:m:s”）；并将setStart改回setStart（\DateTime$start），因为条令需要以这种方式水合实体。
