[RESOLVED] Mysql_num_rows & while(*************) {

[..:RUDI:..]

ok so here's my code:

<?
$threadquery = "SELECT * FROM threads WHERE fid = $forumid";
$threadresult = mysql_query($threadquery);
while ($row = mysql_fetch_assoc($threadresult)) {
$tid = $row['topicid'];
$postquery = mysql_query("SELECT * FROM posts WHERE tid = '".$row['topicid']."';");
}
$countposts = mysql_num_rows($postquery);
echo $countposts ;
?>

from that, I only get 1 result from the num_rows. However, there are two threads, each with a reply, therefore, the post count should be 2.

What I think is happening:

I think that, because

while ($row = mysql_fetch_assoc($threadresult)) {
$tid = $row['topicid']; 

produces an array of numbers for ech thread, maybe the mysql_num_rows() is only getting one of the array members, possibly I could use for each???

Any help is greatly appreciated.

Rudi
