Code for adding multiple Prefixes

[steeler7]

Hi,

This is actually code for vBadvanced to filter news items by Prefix. It works fine except that I want to add more than 1 prefix... I figured the code itself might be basic enough where someone with knowledge could help out

$getnewsids = $db->query_read("
				SELECT $ratingsql threadid, firstpostid
				FROM " . TABLE_PREFIX . "thread AS thread
				WHERE visible = 1
					AND thread.prefixid = 'X'
					AND open != 10
					AND (thread.forumid IN(" . implode(',', $mods['inforums']) . ")
					" . iif(!empty($newstids), ' OR threadid IN(' . implode(',', $newstids) . ')') . "
					)
					" . iif($mod_options['portal_news_cutoffdate'], 'AND thread.dateline > ' . (TIMENOW - ($mod_options['portal_news_cutoffdate'] * 86400))) . "
				ORDER BY " . iif($mod_options['portal_news_sticky'], 'sticky DESC,') . iif($mod_options['portal_news_orderby'] == 'postdateline', 'dateline', $mod_options['portal_news_orderby']) . " $mod_options[portal_news_direction]
				$newslimit
			");

whats in red is my prefix id. I tried duplicating another prefix next to it with and without a comma and no luck
