SELECT id, name, location FROM book WHERE 1 ORDER BY $orderfield DESC
[download]

The above doesn't work when $orderfield is used, but when swapped with the actual field name "id" it works just fine. By not working, I mean it returns with "query returned empty".

After a test print, it shows that $orderfield eq "id" which is the exact name of the column.

Any ideas what might be hanging this up? And would it be possible to also change ASC/DESC to a variable as well?

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
