这需要花一点时间来解释，抱歉。
这段代码是opencart的xml vqmod的一部分，它将所选订单中的订单数据导出到Excel电子表格。在大多数情况下它工作正常。但是有一个障碍，如果有一个记录为特定订单列出了多个advanced_coupon，它将会废弃。
我确定我需要为该输出添加一个数组，并且它是折扣金额的相关字段，但我不知道该怎么做。我是php / MySQL的新手，但学得很快。如果我能指出正确的方向，那就太棒了。
我是新手，但在搜索中找不到相似内容。再次感谢。
以下是相关的代码：

尝试替换：
$worksheet->writeString( $i, $j++, $row['advanced_coupon_code'] );
使用：
foreach( $row['advanced_coupon_code'] as $code )
{
$worksheet->writeString( $i, $j++, $code );
}

在您的查询中，您可以替换此部分：
(SELECT title FROM " . DB_PREFIX . "order_total ot WHERE ot.order_id = o.order_id AND ot.code = 'advanced_coupon') AS advanced_coupon_code,
到这个
(SELECT GROUP_CONCAT(`title`) FROM " . DB_PREFIX . "order_total ot WHERE ot.order_id = o.order_id AND ot.code = 'advanced_coupon' GROUP BY ot.order_id) AS advanced_coupon_code,
或者，如果您信任我，只需将我的$query = ". . . ";字符串替换为我的变体：
$query = "
