How do you prevent the user entering x instead of y in your script?

If your script doesn't allow the user to enter x or y, but derives y from some other input, then don't accept either x or y as input to your stored procedure but, rather, accept only the primary input from which y can be derived.

  • 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.
