Question

In a customer CMS the customer can update their personal information, like change their address and first/last name. I use a mysql UPDATE query for that.

Problem with working like this is, is that people can change their information. E.g. change their name from john doe to asdfdas. I would like to SAVE their old information.

What are my options? What is the best way to do this?

Answer 1

Create new columns for the data being updated column would be prior_to_update_column

On update, move the old info into prior_to_update_column

If the user updates again, append to the prior_to_update_column seperated by , (to look like an array).

This should keep all the previous info the user updates
