No, you want to update the values that the user updated, not the ones that differ from the DB. As a general principle, if a value changes in the DB after the page was loaded and before the form was submitted, then you should preserve the value in the DB, not clobber somebody else's update with this user's non-update. That generally leads to fewer problems and surprises.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
