ecshop商品详细页显示已售商品数量和评论数量

1.在ecshop程序goods.php页面最下面加入这两个函数

function get_buy_sum($goods_id)

{

$sql = 'SELECT IFNULL(SUM(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) {

$sql= "select count(*) from ".$GLOBALS['ecs']->table('comment')." where id_value='".$goods_id."' AND status = 1";

return $GLOBALS['db']->getOne($sql);

}

2.在ecshop程序goods.php中加入

$smarty->assign('buy_num',get_buy_sum($goods_id));

$smarty->assign('comment_num',get_comment_num($goods_id));

在$smarty->display('goods.dwt', $cache_id);之前哈！

3.ecshop中goods.dwt模板中加这个，大概在221行

<!-- {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}-->
