how to find thread poster post count?

[al3bed]

hello,

I think this can be done only by query but if there is another way please tell me!

I tried this:

PHP Code:

$getposterposts = $vbulletin->db->query_read(" SELECT posts FROM " . TABLE_PREFIX . "user
LEFT JOIN " . TABLE_PREFIX . "thread  ON (user.userid = thread.postuserid)");
$getposts = $db->fetch_array($getposterposts)
$getposts[posts] = vb_number_format($getposts[posts]);

if ($getposts[posts] >= $minmum_posts){
/*statments*/} 


but I get an error

help please
