Private Forum Mod or Plug-in Request

[MuratCetin]

Thanks for replies but I have started to writing plug-in.

I created option for 'private_access' (int) value on forum mySQL table and custom field which id is field6 and name is display private forums but it gives an error on search_start hook. Codes are like this:

foreach ($vbulletin->forumcache as $forumid => $foruminfo)
{
	if ($foruminfo['private_access'] AND !$vbulletin->userinfo['field6'])
	{
			$vbulletin->userinfo['forumpermissions'][$forumid] = $vbulletin->userinfo['forumpermissions'][$forumid] ^ $vbulletin->bf_ugp_forumpermissions['canviewthreads'];
	}
}

My think is like that, if $foruminfo['private_access'] is true and $vbulletin->userinfo['field6'] (display private forums) is false disable showing private threads on search results. But when I use this code, forum search said that, forum id is invalid. So who can help me for fix this code? If we fix this, I will share this plug-in.

Thanks.
