ecshop商品列表頁面增加按銷量排行

1：在表“ecs_goods”添加字段：salesnum（注：自定義字段名）

2：打開根目錄下文件：flow.php

找到

    /* 插入訂單商品 */
    $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：打開文件：default\library\goods_list.lbi，找到下面的代碼：

<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=<!-- {if $pager.sort == 'last_update' && $pager.order == 'DESC'} -->ASC<!-- {else} -->DESC<!-- {/if} -->#goods_list"><img src="images/last_update_<!-- {if $pager.sort == 'last_update'} -->{$pager.order}<!-- {else} -->default<!-- {/if} -->.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="按銷量排行"></a>

4：打開文件：category.php，找到如下代碼：

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

修改爲

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