大家在淘宝上看到产品到某某地 会出现相应的运费，若是ECSHOP，该如何增加该功能，A5为大家分解！

1:flow.php增加以下代码

elseif ($_REQUEST['step'] == 'show_shipping1')

{

include_once('includes/cls_json.php');

$json = new JSON;

$result = array('error' => '', 'content' => '', 'need_insure' => 0);

/*购买属性*/

$attr_id = isset($_REQUEST['attr']) ? explode(',', $_REQUEST['attr']) : array();

/*购买数量*/

$number = (isset($_REQUEST['number'])) ? intval($_REQUEST['number']) : 1;

/*商品ID*/

$goods_id = (isset($_REQUEST['goods_id'])) ? intval($_REQUEST['goods_id']) : '0';

/*计算商品价格*/

$shop_price = get_final_price($goods_id, $number, true, $attr_id);

$r = $db -> getRow("select * from ".$ecs->table('goods')." where goods_id = '$goods_id'");

/*取得商品总重量*/

$row['weight'] = floatval(($r['goods_weight']*$number));

/*取得商品总价格*/

$row['amount'] = floatval(($shop_price*$number));

/*购买数量*/

$row['number'] = intval($number);

/* 格式化重量 */

$row['formated_weight'] = formated_weight($row['weight']);

/*取得区域*/

$string = trim($_REQUEST['string']);

$ar = explode(",",$string);

$region = array($ar[0], $ar[1], $ar[2], $ar[3]);

/*取得区域对应的配送方式*/

$shipping_list = available_shipping_list($region);

$cart_weight_price =$row;

$insure_disabled = true;

$cod_disabled = true;

// 查看购物车中是否全为免运费商品，若是则把运费赋为零

$sql = 'SELECT count(*) FROM ' . $ecs->table('cart') . " WHERE `session_id` = '" . SESS_ID. "' AND `extension_code` != 'package_buy' AND `is_shipping` = 0";

$shipping_count = $db->getOne($sql);

foreach ($shipping_list AS $key => $val)

{

$shipping_cfg = unserialize_config($val['configure']);

$shipping_fee = ($shipping_count == 0 AND $cart_weight_price['free_shipping'] == 1) ? 0 : shipping_fee($val['shipping_code'], unserialize($val['configure']),

$cart_weight_price['weight'], $cart_weight_price['amount'], $cart_weight_price['number']);

$shipping_list[$key]['format_shipping_fee'] = price_format($shipping_fee, false);

$shipping_list[$key]['shipping_fee'] = $shipping_fee;

$shipping_list[$key]['free_money'] = price_format($shipping_cfg['free_money'], false);

$shipping_list[$key]['insure_formated'] = strpos($val['insure'], '%') === false ?

price_format($val['insure'], false) : $val['insure'];

/* 当前的配送方式是否支持保价 */

if ($val['shipping_id'] == $order['shipping_id'])

{

$insure_disabled = ($val['insure'] == 0);

$cod_disabled = ($val['support_cod'] == 0);
}

}

$smarty -> assign('list',$shipping_list);

$result[content] = $smarty->fetch('library/goods_total.lbi');

//echo $json->encode($shipping_list);

echo $json->encode($result);

exit;

}
