ecshop订单中只要有一个是包邮商品，就整个订单都包邮

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

修改为

$sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('cart') . " WHERE  `session_id` = '" . SESS_ID. "' AND `extension_code` != 'package_buy' AND `is_shipping` = 1";

$total['shipping_fee'] = ($shipping_count == 0 AND $weight_price['free_shipping'] == 1) ?0 :  shipping_fee($shipping_info['shipping_code'],$shipping_info['configure'], $weight_price['weight'], $total['goods_price'], $weight_price['number']);

$total['shipping_fee'] = ($shipping_count >= 1 AND $weight_price['free_shipping'] == 1) ?0 :  shipping_fee($shipping_info['shipping_code'],$shipping_info['configure'], $weight_price['weight'], $total['goods_price'], $weight_price['number']);
