微信--订单处理页:
<?php
include("WxPayPubHelper.php");
//使用jsapi接口
$jsApi = new JsApi_pub();
//=========步骤1:网页授权获取用户openid============
//通过code获得openid
if (!isset($_GET[‘code‘]))
{
//触发微信返回code码
$url = $jsApi->createOauthUrlForCode(WxPayConf_pub::JS_API_CALL_URL);
ecs_header("Location: $url");
}else
{
//获取code码,以获取openid
$code = $_GET[‘code‘];
$jsApi->setCode($code);
$openid = $jsApi->getOpenId();
if(!empty($openid))
{
goto获取到相应的订单参数
}
//=========步骤2:使用统一支付接口,获取prepay_id============
//使用统一支付接口
$unifiedOrder = new UnifiedOrder_pub();
//设置统一支付接口参数
//设置必填参数
//appid已填,商户无需重复填写
//mch_id已填,商户无需重复填写
//noncestr已填,商户无需重复填写
//spbill_create_ip已填,商户无需重复填写
//sign已填,商户无需重复填写
$unifiedOrder->setParameter("openid","$openid");//商品描述
$out_trade_no = $order[‘order_sn‘];
$unifiedOrder->setParameter("body","$goods_name");//商品描述
//自定义订单号,此处仅作举例
//$timeStamp = time();
//$out_trade_no = WxPayConf_pub::APPID."$timeStamp";
$total_fee = $total[‘amount‘]*100;
$unifiedOrder->setParameter("out_trade_no","$out_trade_no");//商户订单号
$unifiedOrder->setParameter("total_fee","$total_fee");//总金额
$unifiedOrder->setParameter("notify_url",WxPayConf_pub::NOTIFY_URL);//通知地址
$unifiedOrder->setParameter("trade_type","JSAPI");//交易类型
//非必填参数,商户可根据实际情况选填
//$unifiedOrder->setParameter("sub_mch_id","XXXX");//子商户号
//$unifiedOrder->setParameter("device_info","XXXX");//设备号
//$unifiedOrder->setParameter("attach","XXXX");//附加数据
//$unifiedOrder->setParameter("time_start","XXXX");//交易起始时间
//$unifiedOrder->setParameter("time_expire","XXXX");//交易结束时间
//$unifiedOrder->setParameter("goods_tag","XXXX");//商品标记
//$unifiedOrder->setParameter("openid","XXXX");//用户标识
//$unifiedOrder->setParameter("product_id","XXXX");//商品ID
$prepay_id = $unifiedOrder->getPrepayId();
//=========步骤3:使用jsapi调起支付============
$jsApi->setPrepayId($prepay_id);
$jsApiParameters = $jsApi->getParameters();
//$jsApiParameters = json_encode($jsApiParameters);
$smarty->assign(‘pay_online‘, $jsApiParameters);
$smarty->assign(‘openid‘,$openid);
$smarty->assign(‘order_id‘,$order_id);//订单id用于支付成功跳转订单页
$smarty->display(‘order_done.dwt‘);
//echo $jsApiParameters;
