1.打开 goods.php 文件，在此文件最下面加入如下两个函数
function get_buy_sum($goods_id"
{
$sql = 'SELECt INULLSUM(g.goods_number", 0" ' .
'FROM ' . $GLOBALS['ecs']->table('order_info'" . ' AS o, ' .
$GLOBALS['ecs']->table('order_goods'" . ' AS g ' .
"WHERe o.order_id = g.order_id " .
"AND o.order_status = '" . OS_ConFIRMED . "' " .
"AND o.shipping_status " . db_create_in(array(SS_SHIPPED, SS_RECEIVED"" .
" AND o.pay_status " . db_create_in(array(PS_PAYED, PS_PAYING"" .
" AND g.goods_id = '$goods_id'";
return $GLOBALS['db']->getOne($sql";
}
function get_comment_num($goods_id" {
$sql= "sel ect count(*" from ".$GLOBALS['ecs']->table('comment'"." where id_value='".$goods_id."' AND status = 1";
return $GLOBALS['db']->getOne($sql";
}
2.继续修改 goods.php 文件
找到
$smarty->display('goods.dwt', $cache_id";
在此代码前面添加
$smarty->assign('buy_num',get_buy_sum($goods_id"";
$smarty->assign('comment_num',get_comment_num($goods_id"";
3.打开 /themes/模板文件夹/goods.dwt 文件，在需要的地方加入如下代码
<!-- {if $buy_num} 已出售量-->
<li class="clearfix">
<dd>
<strong>累计售出：</strong>{$buy_num}
</dd>
</li>
<!--{/if}-->
<!-- {if $comment_num} 评论数量-->
<li class="clearfix">
<dd>
<strong>评论数量：</strong><a href="#comment">{$comment_num}</a>
</dd>
</li>
<!--{/if}-->
