I agree that using field names as query parameters is not a good idea. I don't know why it worked before, because SELECT x FROM y ORDER BY 'z' is not valid SQL. Perhaps MySQL 4 was a bit relaxed on its syntax.

I can see only two possible strategies to solve the proble: (a) if you can change the values returned by getQuery() you can replace the placeholders "?" in the ORDER BY clauses with something else (perhaps "??") or (b) you have to write a parser that recognizes the ORDER BY clause and.

In both cases you must preprocess the query before passing it to prepare(), then execute() can replace the placeholders with real values

Rule One: "Do not act incautiously when confronting a little bald wrinkly smiling man."
