SORRY - one small correction below:
<SNIP>
If that were instead an $s then I would do:
<?php //IF there is a valid query by subject, use $s to build the SQL
$fields = "SELECT art.*,publisher.*,subject.*";
$from = "FROM art,subject
LEFT JOIN publisher
ON publisher.publisher_id=art.publisher_id";
$where = "WHERE publisher.publisher_id=art.publisher_id AND
art.subject_id = '$s' AND
art.subject_id=subject.subject_id";
?>
</SNIP>
I had accidentally put a number 1 in place of the $s in the above
example. Apologies for the extra mail and thanks in advance.
