It's worth noting that MySQL will optimize UPDATEs so that it won't update a field to a value that's already stored in that field... UPDATE table SET name="John Smith" WHERE id=1 will turn into a no-op if name is already set to "John Smith".

Unless your user list is very very long it might be a good idea to just update every field for every record every time "submit" is pressed. I suspect the performance impact will be minimal, and you don't have to mess with JavaScript or anything hinky like that.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
