帝国CMS列表模板中计算统计所有信息下载字段downpath的点数

downpath如果在副表：

$ff=$empire->fetch1("select downpath from{$dbtbpre}ecms_download_data_'$r[stb]' where id='$r[id]' limit 1");
$down=explode(egetzy('rn'),$ff['downpath']);
$count = count($down);
$sum = 0;
for($i = 0; $i <$count; $i++) {
$fr = explode("::::::", $down[$i]);
$sum += $fr[3];
}
$listtemp=' <li><a href="[!--titleurl--]" title="[!--title--]'.$sum.'" target="_blank"><img class="lazy" data-original="[!--titlepic--]" width="500" height="330" alt=""/><span>[!--title--]'.$count.'</span></a></li>';

downpath如果在主表：

$down=explode(egetzy('rn'),$r['downpath']);
$count = count($down);
$sum = 0;
for($i = 0; $i <$count; $i++) {
$fr = explode("::::::", $down[$i]);
$sum += $fr[3];
}
$listtemp=' <li><a href="[!--titleurl--]" title="[!--title--]'.$sum.'" target="_blank"><img class="lazy" data-original="[!--titlepic--]" width="500" height="330" alt=""/><span>[!--title--]'.$count.'</span></a></li>';
