根据运营改造定制的特殊需求，不一定适合每个人。PW默认的广告位可以设置随机显示，但是不同广告多个楼层同时展示时会出现随机重复，这给广告投放带来不便，所以改造一下让它真正按广告条数比例均匀分配随机轮转起来。此方法改造过后后台新增广告理论上跟原来一样，如有错误请检查是否包含违反JS语法的特别符号。改造过后，论坛首页分类间后台的楼层设置仅作随机轮转楼层范围设置，原来的指定楼层显示功能取消。

随机轮转广告位对于客户来讲机会均等，统一定价排位不分先后随机轮转展示，销售会便利很多。

1、将后台>运营>广告管理>论坛首页分类间广告位的广告显示方式设置为“显示全部”。

2、require/common.php，在 pwAdvert 整个函数下新增：

function pwAdvert4JS($advKey, $fid = 0, $lou = -1, $scr = 0) {
global $timestamp, $db_advertdb, $db_mode, $_time;
if (empty($db_advertdb[$advKey])) return false;
$hours = $_time['hours'] + 1;
$fid || $fid = $GLOBALS['fid'];
$scr || $scr = $GLOBALS['SCR'];
$scr = strtolower($scr);
$lou = (int) $lou;
$tmpAdvert = $db_advertdb[$advKey];
if ($db_advertdb['config'][$advKey] == 'rand') {
shuffle($tmpAdvert);
}
$arrAdvert = array();
$advert = '';
foreach ($tmpAdvert as $key => $value) {
if ($value['stime'] > $timestamp || $value['etime'] < $timestamp || ($value['dtime'] && strpos(",{$value['dtime']},", ",{$hours},") === false) || ($value['mode'] && strpos($value['mode'], $db_mode) === false) || ($value['page'] && (strpos($value['page'], ",$scr,") === false || ($scr == 'read' && $value['page'] == 'thread'))) || ($value['fid'] && $scr != 'index' && strpos(",{$value['fid']},", ",$fid,") === false) || ($value['lou'] && strpos(",{$value['lou']},", ",$lou,") === false)) {
continue;
}
if ((!$value['ddate'] && !$value['dweek']) || ($value['ddate'] && strpos(",{$value['ddate']},", ",{$_time['day']},") !== false) || ($value['dweek'] && strpos(",{$value['dweek']},", ",{$_time['week']},") !== false)) {
$arrAdvert[] = $value['code'];
$advert .= is_array($value['code']) ? "'".$value['code']['code']."'," : "'".$value['code']."',";
if ($db_advertdb['config'][$advKey] != 'all') break;
}
}
return array($advert, $arrAdvert);
}
