【问题描述】：
我有一个表格可以在我的数据库中插入书籍的详细信息。我的数据库中有 4 个表 1）ssc_eng 2）ssc_hindi 3）ssc_urdu 4）ssc_marathi。在我的 insert_book 表单中，它们是一个下拉列表，其中包含上述表格。如果管理员从下拉列表中选择这些表之一，则管理员以 insert_book 形式插入的所有数据都应插入到选定的下拉项中，该下拉项是我数据库中的表。所以，我在搭售但没有得到逻辑。示例：如果管理员在下拉列表中选择“ssc_eng”，则表单中的所有数据都必须插入到我数据库的“ssc_eng”表中。
总结问题：
Use drop down list to insert form data to the selected database of the drop down list
