【问题描述】：

在这里完成新手，我正在尝试将数据从一组 tkinter 输入框提交到 sqlite3。当我运行代码时，表单正确显示并创建了表，但数据没有提交到数据库。我收到一条错误消息，提示未定义连接到提交按钮的函数“submit_record”。我已经尝试了所有我知道或可以在网上找到的东西。如果可以的话请帮忙。为这件事苦苦挣扎了 2 周！谢谢。

【解决方案1】：

您的代码中有更多不一致之处。

首先，当您有 staff_dtls 时，例如self.lname_entry.get()，你必须定义self.lname_entry，仅仅有lname_entry是不够的，因为Python Classes and OOP theory。

接下来，变量名有些混乱，例如在staff_dtls 你有self.inc_type.get()，但你必须有self.inc_type_entry.get()，反之亦然，你有例如 ue_tax = ttk.Entry(box2, textvariable=ue_tax_entry_value)，但你需要ue_tax_entry = ttk.Entry(box2, textvariable=ue_tax_entry_value)。所以精确地结合你的变量名。

接下来，您需要像 self.c.execute("INSERT INTO staffing VALUES (?, ?, ?, ?, ?, ?, ...)", (element)) 这样的东西，而不是 c.excecute("INSERT INTO staffing VALUES (?)", (element))（带有拼写错误），其中包含这么多问号，您要向 DB 插入多少列。

这些是您修复它们时的主要错误，您将走在正确的轨道上。
