将此表单放在弹出框（Angular Material）中，在此表单中我有5个输入字段和2个选择列表。我可以使用数据库中的数据填充选择列表，我也可以保存数据，但只能从输入字段中保存，因此不能从选择框中保存。所以我想知道如何将选定的选项从选择列表保存到我的数据库。
我正在使用Angular和PHP作为后端db的情况如下：3个表
来自tblLocation的id和tblProjectType引用返回tblTask（外键）
我在php和app.js文件中添加项目类型的引用然后它将不再保存到db。在控制台中发生以下情况 - ＆gt; http://gyazo.com/d9a7b1ef3f60b441fb37c807772a709c
但是当我退出时，我能够保存5个输入字段中的所有数据。

对于那些可能与我有更多相同问题的人。我的问题的解决方案是我删除了外键，然后选择列表的值将保存到我的数据库
