Question

我正在导入CSV文件，并将其添加到我的数据库表中。在下一页中，我想向刚刚插入表中的数据添加信息。此数据将插入import_map表。

当选择Table1Model选项时，它将根据map_table使用Ajax在Table2Model选择框中选择选项。我无法在id中创建map_table字段并将其插入import_map表，因为用户可以在Table2Model选择框中选择与{无关}的选项{1}}。

我的想法是在table1方法中构建一个包含选定值的数组。但问题是它似乎没有达到add()方法的if($this->request->is('ajax'))部分。至少，当选择一个选项时，它根本没有做任何事情。

map_table
