Trying to create $forum['subscribed'] conditional

[kyrnel]

Like the title says..
If I can create a conditional that indicates whether a forum is subscribed to, then I can add an indicator on ForumHome that alloows a user to subscribe/unsubscribe.

I tried adding this code to functions_forumlist.php:

PHP Code:

// %%%%%%%%%%%%%%%%%%%% added code for forum subscriptions %%%%%%%%%%%%%%%%%%%%
 
$xquery = "SELECT subscribeforumid FROM " . TABLE_PREFIX . "forum AS forum 
 
LEFT JOIN " . TABLE_PREFIX . "subscribeforum AS subscribeforum ON ((subscribeforum.forumid = 
 
forum.forumid) AND (subscribeforum.userid = $bbuserinfo[userid]))";
 
$forum['subscribed'] = false;
 
$xsubscriptions = $DB_site->query($xquery);
 
if ($DB_site->num_rows($xsubscriptions))
 
{
 
while ($xsub = $DB_site->fetch_array($xsubscriptions))
 
{
 
if ($xsub(subscribeforumid) = $forum[forumid])
 
{
 
$forum['subscribed'] = true;
 
} 
 
}
 
}
 
// %%%%%%%%%%%%%%%%% ENd added %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 


But it doesnt seem to work, I get a parse error on the 'while' statement.
Anyone have a sugeestions or alternative approaches, I'd appreciate it.

Thx
