Adding attachments into external.php

[ManagerJosh]

I'm trying to list attachments in external.php so we can see what's files are available.

PHP Code:

if ($_REQUEST['type'] == 'RSS2')
{ // check for attachments
$attachments = $DB_site->query("
SELECT attachment.filename, attachment.filesize, attachment.visible, attachment.attachmentid, attachment.counter, post.postid
FROM " . TABLE_PREFIX . "attachment
WHERE post.postid = $postid
ORDER BY attachment.dateline
");
while ($attachment = $DB_site->fetch_array($attachments))
{
$post['attachments']["$attachment[attachmentid]"] = $attachment;
}
} 


That code gives me a database error,


Invalid SQL: SELECT attachment.filename, attachment.filesize, attachment.visible, attachment.attachmentid, attachment.counter, post.postid FROM attachment WHERE post.postid = ORDER BY attachment.dateline mysql error: You have an error in your SQL syntax near 'ORDER BY attachment.dateline ' at line 5mysql error number: 1064


So yea, didn't work...ideas?
