Javascript 选择列表的选定值未保存到具有角度的db
有一个弹出框角材料，在这个形式，我有5个输入字段和2个选择列表的形式。我可以用数据库中的数据填充选择列表，也可以保存数据，但只能保存输入字段中的数据，所以不能保存选择框中的数据。因此，我想知道如何将所选选项从选择列表保存到我的数据库中 我正在为后端使用Angular和PHP。db的情况如下：3个表 任务 分配 TBL项目类型 tblLocation中的id和tblProjectType都引用回tblTask外键 当我在php和app.js文件中添加项目类型的引用时，它将不再保存到数据库中。在控制台中发生以下情况-> 但是，当我省略它时，我能够保存来自5个输入字段的所有数据 HTML代码：Javascript 选择列表的选定值未保存到具有角度的db,javascript,php,angularjs,material-design,Javascript,Php,Angularjs,Material Design,有一个弹出框角材料，在这个形式，我有5个输入字段和2个选择列表的形式。我可以用数据库中的数据填充选择列表，也可以保存数据，但只能保存输入字段中的数据，所以不能保存选择框中的数据。因此，我想知道如何将所选选项从选择列表保存到我的数据库中 我正在为后端使用Angular和PHP。db的情况如下：3个表 任务 分配 TBL项目类型 tblLocation中的id和tblProjectType都引用回tblTask外键 当我在php和app.js文件中添加项目类型的引用时，它将不再保存到数据库中。在控制

对于那些在未来可能与我有同样问题的人。我的问题的解决方案是删除外键，然后选择列表的值将保存到我的数据库中是否出现数据库错误？你可以跟我核对一下。此外，不推荐使用mysql_*函数。它们将在PHP的未来版本中删除。不，我没有收到任何db错误
