Hello all,
I encountered a problem with my kunena forum since I've updated it (1.6.5 to 1.7.0). All my categories are moderated and have the "Review posts setting" set to TRUE. When I want to write a new subject, I have this php error just after submit:
Notice: Trying to get property of non-object in components/com_kunena/lib/kunena.link.class.php on line 503
When I set to false the "Review posts setting" I've no problem. When I write a post in a non empty category, I've no problem too.
I've searched line 503 in the source code, in GetMessageUrl function:
Code:
return KunenaRoute::_ ( KUNENA_LIVEURLREL . '&func=showcat&catid=' . $result->catid, $xhtml );
The problem is $result, which is null.
I've isolated problematic code
Code:
$kunena_db->setQuery ( "SELECT a.thread AS thread, {$maxmin}(a.id) AS latest_id, MAX(a.catid) AS catid, COUNT(*) AS totalmessages
FROM #__kunena_messages AS a, (SELECT thread FROM #__kunena_messages WHERE id={$kunena_db->Quote($pid)}) AS b
WHERE a.thread = b.thread AND a.hold IN ({$hold}) AND a.id {$topic_ordering} {$kunena_db->Quote($pid)}
GROUP BY a.thread" );
$result = $kunena_db->loadObject ();
if (KunenaError::checkDatabaseError()) return;
if (! is_object ( $result ))
return KunenaRoute::_ ( KUNENA_LIVEURLREL . '&func=showcat&catid=' . $result->catid, $xhtml );
return CKunenaLink::GetThreadPageURL ( 'view', $result->catid, $result->thread, ceil ( $result->totalmessages / $limit ), $limit, $result->latest_id, $xhtml );
In the case of an empty category, the query return nothing. So $result is not an object, but we do $result->catid...
Thank you in advance for your answers.
