Question

* 仍在等待此问题的答案 *

我是HTML＆amp; amp;的新手PHP。我需要开发一个交互式月度账户管理表来管理我的每月公用事业账单支付记录。

我需要做什么？ 我喜欢使用一个HTML表单，用于提交一组新数据，检索特定月份和年份的数据集，以及更新月份和年份特定记录的数据字段。

已完成的工作：

在MySQL DB中创建了名为“monthlyaccount”的表共有9列：月，年，电，水，电缆，电话，抵押贷款，CarLoan，保险
创建了一个包含9个输入字段的HTML表单（Month除外）和年份，所有7个输入字段都是数字类型）
表单中有3个按钮：提交，检索和更新

应该做什么：

提交按钮：在我填写表格后，点击数据提交按钮，将调用一个php文件（putDataToDB.php）后端将连接MySQL DB并将数据插入到在表格中输入的数据库表
检索按钮：在HTML表单中，我只会填写月份和年份输入数据字段，然后单击将获取的Retrieve按钮 MySQL DB中该月份和年份的数据并显示它们在表格的其余7个字段
更新按钮：我检索了一个月的数据后（通过检索按钮），我可以更新或更正任何特定的数据字段，然后单击更新按钮，它将更新MySQl DB中的特定数据

有关PHP编程的注意事项：

我对所有三个按钮使用了type =“ submit ”（提交，检索）和前端HTML代码中的更新）
在后端 PHP ，我正在使用“ isset（）”功能检查一下按钮已被点击
如果点击“提交”，则会使用 INSERT 将所有数据插入到 MySQL DB表通过在表中插入一个新的特定行月和年
如果点击“检索”，它将使用 SELECT * FROM monthlyaccout 来获取特定月份和年份的所有数据（使用 WHERE 子句）从MySQL DB中将它们呈现在提交的HTML表单相同
如果点击“更新”，它将使用UPDATE更新现有内容特定月份和年份的数据字段

我需要帮助的地方：在PHP函数内部， retrieveDataForAMonthYearAndPutOnTheForm（）

创建表单的HTML代码：
