Yes. Just go ahead, and echo $sql to see what you have. You can build quite
complex queries this way, dependent upon input from picklists, checkboxes,
etc., adding and dropping conditions according to whether or not they have
So why not $sql = " UPDATE $fieldlist $wherecondition" ?
When we think about it a bit, if we are assigning a SQL statement to $sql,
we are passing a dynamic variable to mysql_query(), so why not create it
