ecshop产品列表增加市场价后台编辑功能的方法

ecshop系统中本店价格是可以在列表里调整的，市场价是按1.2比例自动加的，但是有的时候改本店价市场价出现不是整数的情况，所以需要市场价也可以在列表页直接编辑。

1、打开 /admin/templates/goods_list.htm 文件
<a href="javascript：listTable.sort('goods_sn');">{$lang.goods_sn}</a>
市场价
在货号后增加市场价一栏，因为都是中文的，就没有写入语言包文件
{$goods.goods_sn}
{$goods.market_price}

2、打开 /admin/goods.php 文件
增加下面的部分
/*------------------------------------------------------ */
//-- 修改市场价格
/*------------------------------------------------------ */
elseif ($_REQUEST['act'] == 'edit_market_price')
{
check_authz_json('goods_manage');
$goods_id       = intval($_POST['id']);
$goods_price    = floatval($_POST['val']);
if ($goods_price < 0 || $goods_price == 0 && $_POST['val'] != "$goods_price")

make_json_error($_LANG['shop_price_invalid']);
}
else
{
if ($exc->edit(" market_price = '$goods_price', last_update=" .gmtime(), $goods_id))
{
clear_cache_files();
make_json_result(number_format($goods_price, 2, '.', ''));
}
}
}

3、打开 /admin/includes/lib_goods.php 文件
在 function goods_list 函数约910行
$filter = page_and_size($filter);
$sql = "SELECT goods_id, goods_name, goods_type, goods_sn, shop_price,market_price,
