1.在sq執行語句

ALTER TABLE `ecs_goods` ADD `sales_volume_base` INT( 10 ) UNSIGNED NOT NULL DEFAULT '0'  
 
INSERT INTO `ecs_shop_config` (`parent_id`, `code`, `type`, `store_range`, `store_dir`, `value`, `sort_order` ) VALUES ('7','show_goods_sales', 'select', '1,0', '', '1', '1');  
 
INSERT INTO `ecs_shop_config` (`parent_id`
 
, `code`, `type`, `store_range`, `store_dir`, `value`, `sort_order` ) VALUES ('3', 'show_sales_type', 'select', '1,0', '', '1', '1');  

注意：如果你的資料表字首不是‘ecs_’ 請自行修改 2./admin/includes/lib_goods.php中

$sql = "SELECT goods_id, goods_name, goods_type, goods_sn, shop_price, is_on_sale, is_best, is_new, is_hot, sort_order, goods_number, integral, " .  
            " (promote_price > 0 AND promote_start_date <= '$today
 
' AND promote_end_date >= '$today') AS is_promote ".  
            " FROM " . $GLOBALS['ecs']->table('goods') . " AS g WHERE is_delete='$is_delete' $where" .  
            " ORDER BY $filter[sort_by] $filter[sort_order] ".  
            " LIMIT " . $filter['start'] . ",$filter[page_size]";  

修改為        

 $sql
 
 = "SELECT goods_id, goods_name, goods_type, goods_sn, shop_price, is_on_sale, is_best, is_new, is_hot, sort_order, goods_number, integral, sales_volume_base, " .   
                    " (promote_price > 0 AND promote_start_date <= '$today' AND promote_end_date >= '$today') AS is_promote ".  
                    " FROM " . $GLOBALS['ecs']->table('goods') . " AS g WHERE is_delete='$is_delete' $where" .  
                    " ORDER BY $filter[sort_by] $filter[sort_order] ".  
                    " LIMIT " . $filter['start'] . ",$filter[page_size]";
