What programming interface are you using for the form? Most usually
provide some sort of escaping mechanism before you insert data into the
database. Otherwise, you can write your own validation functions (which
you should do any way, to make sure users aren't doing bad things) to
escape funncy characters (single quotes, slashes, etc.).
