ECSHOP系统的商品分类页默认只能按价格排序的，却没有按销量排序的，通过本教程就可以实现按销量排行
教程开始

1：在表“ecs_goods”添加字段：salesnum（注：自定义字段名）
2：打开根目录下文件：flow.php
找到

/* 插入订单商品 */

$sql = "INSERT INTO " . $ecs->table('order_goods') . "( " .

            "order_id, goods_id, goods_name, goods_sn, product_id, goods_number, market_price, ".

            "goods_price, goods_attr, is_real, extension_code, parent_id, is_gift, goods_attr_id) ".

        " SELECT '$new_order_id', goods_id, goods_name, goods_sn, product_id, goods_number, market_price, ".

            "goods_price, goods_attr, is_real, extension_code, parent_id, is_gift, goods_attr_id".

        " FROM " .$ecs->table('cart') .

        " WHERE session_id = '".SESS_ID."' AND rec_type = '$flow_type'";

$db->query($sql);

在下面添加

$sql = "update " .$GLOBALS['ecs']->table('goods') . " AS a, ".$GLOBALS['ecs']->table('cart') . " AS b ".

" set a.salesnum= a.salesnum + b.goods_number".

" WHERE a.goods_id=b.goods_id AND b.session_id = '".SESS_ID."' AND b.rec_type = '$flow_type'";

$db->query($sql);

3：打开文件：default/library/goods_list.lbi，找到下面的代码：

<a href="category.php?category={$category}&display={$pager.display}&brand={$brand_id}&price_min={$price_min}&price_max={$price_max}&filter_attr={$filter_attr}&page={$pager.page}&sort=last_update&order=ASCDESC#goods_list"><img src="images/last_update_{$pager.order}default.gif" alt="{$lang.sort.last_update}"></a>

在下面添加

<a href="category.php?category={$category}&display={$pager.display}&brand={$brand_id}&price_min={$price_min}&price_max={$price_max}&filter_attr={$filter_attr}&page={$pager.page}&sort=salesnum&order=<!–- {if $pager.sort == 'salesnum' && $pager.order == 'DESC'} -–>ASC<!–- {else} -–>DESC<!-– {/if} -–>#goods_list"><img src="images/sales_<!–- {if $pager.sort == 'salesnum'} -–>{$pager.order}<!–- {else} -–>default<!-– {/if} -–>.gif" alt="按销量排行"></a>

4：打开文件：category.php，找到如下代码：

$sort = (isset($_REQUEST['sort']) && in_array(trim(strtolower($_REQUEST['sort'])), array('goods_id', 'shop_price', 'last_update'))) ? trim($_REQUEST['sort']) : $default_sort_order_type;

修改为

$sort = (isset($_REQUEST['sort']) && in_array(trim(strtolower($_REQUEST['sort'])), array('goods_id', 'shop_price', 'last_update', 'salesnum'))) ? trim($_REQUEST['sort']) : $default_sort_order_type;
