What am I missing here?
select m.*, d.discussion, d.discussion_id, u.user_id, t.topic_id
from forums_messages
left join forums_members m, forums_discussions d, users u, forums_topics t
on m.topic_id = t.topic_id, t.discussion_id = d.discussion_id
where m.topic_id = "1";
Is it legal to do multiple joins like this?
Thanks

forum_messages does not take part in any selection or any where clause.
You have 5 tables listed, with only 4 of them appearing in 2 disjointed,
and improperly formed joins.
From the comma separated table list after a LEFT JOIN, I am not sure
whether you intend them to be LEFT JOINs or INNER JOINs.
Try:
SELECT fields
FROM file1
LEFT JOIN file2 ON something
INNER JOIN file3 ON something
INNER JOIN file4 ON something
INNER JOIN file5 ON something
WHERE somecondition
