Reply to a thread/topic

[Username:]

I've already made fully working create topic, etc; what would I need to make to reply to a thread?

 

I've gotten this so far...

<?php
$result = mysql_query("SELECT id FROM b ORDER BY id DESC");
while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
    printf("<a href='reply.php?id=%s'>Reply</a><hr><br /><br />", $row[0]);
}

mysql_free_result($result);
?>

reply.php?id=%s (%s equaling the thread id) when I click it, it does bring me to the appropriate page, but I don't know where to go from there. Any help?  :shrug:

any other info you might need just ask

Assuming your table has a 'parent' field or equivelent, the id from the original post needs to be inserted into it.
