Ecshop实现仿淘宝按地区显示运费
淘宝网（Taobao）购物的宝贝详情页面，可以针对不同地区显示不同运费，运费由后台设定；结算时间，按重量、件数计算运费。Ecshop本身有配送方式插件，已有多家物流公司插件，例如：顺丰快递、申通快递、圆通快递等。本文介绍如何实现按地区显示运费，并且让每个商品绑定运费模板。
1、Ecshop后台配送方式创建
进入Ecshop后台"系统设置-->配送方式"，将“顺丰快递”改名称为“粮食快递”，配送ID号为6。
2、商品绑定配送方式的运费模板
2.1 数据表“ecs_goods”增加一个字段，执行下面SQL语句：
|
1
|
ALTER TABLE `ecs_goods` ADD `shipping_id` MEDIUMINT(9) NOT NULL DEFAULT '6';
|
2.2 后台添加/编辑 商品 调出已经安装配送方式 "admin/ goods.php "，将此shipping_list函数添加到goods.php最末处。

/**
* 取得已安装的配送方式
* @return array 已安装的配送方式
*/
function shipping_list()
{
$sql = 'SELECT shipping_id, shipping_name ' .
'FROM ' . $GLOBALS['ecs']->table('shipping') .
' WHERE enabled = 1';
return $GLOBALS['db']->getAll($sql);
}
|
在代码前“$smarty->assign('unit_list', get_unit_list());”增加调用代码
|
1
2
3
4
|
// LONGHTML 增加运费模板
$smarty->assign('shipping_list', shipping_list());
// END
$smarty->assign('unit_list', get_unit_list());
|
在“/* 处理商品数据 */”后面，增加POST过来的“shipping_id ”表单值进行赋值
|
1
2
3
4
5
|
/* 处理商品数据 */
// LONGHTML 运费模板（新增，更新）
$shipping_id = empty($_POST['shipping_id']) ? '0' : intval($_POST['shipping_id']);
// END
|
最后一步是“插入/更新”商品时，对“shipping_id”字段实现处理。直接替换掉下面代码

2.3 后台添加/编辑商品 实现绑定配送方式"admin/goods_info.htm"

<tr>
<td class="label">运费模板</td>
<td><select name="shipping_id" ><option value="0">{$lang.select_please}
{foreach from=$shipping_list item=shipping}
<option value="{$shipping.shipping_id}" {if $shipping.shipping_id eq $goods.shipping_id}selected{/if}>{$shipping.shipping_name}</option>
{/foreach}
</select>{$lang.require_field}</td>
</tr>
|
在品牌下面，增加绑定运费模板。效果如下：
3、前台商品详情调用设置好的配送方式
以主题default为例，增加新文件：
1、chrome.js （themes/default/js）
2、icon_2.jpg （themes/default/images）相关文件下载
goods.php页面商品显示部分加入调用代码

前台显示最终效果图，默认广东省
4、结算流程中，根据配送地址计算运费
4.1 重写“include/lib_order.php”中last_shipping_and_payment函数。多个商品，不同配送方式，调用配送方式ID，以最贵配送方式计算。买家可以找客服进行，运费改价。
