问题描述
大家好，我需要确定文本框是否已更改的帮助，如果它必须更新MySQL表中的旧值和新值，我得到了一个审计表，该表将存储所有这些更改
例如
tbfirst_name = john，然后更改为jane
现在，如果用户更改了该文本框并提交了新值，我需要选择旧值(john)并将其存储在旧值单元格以及新值(jane)中并将其存储在新值单元格中，如果用户未更改其信息，即时消息将如何提取
感到困惑

hi all, i need help with determining if a text box has changed or not, and if it has it must update the old value and the new value in a MySQL table, i got a audit table that will store all these changes
for example
tbfirst_name = john and then changes to jane
now if the user changes that textbox and submits the new values i need to pick up the old value (john) and store that in the old value cell aswell as the new value (jane) and store that in the new value cell, im just confused on how im going to pick up if the user has changed their info or not
