发现csdn上的人少了，PHP版微信支付通过STATE传自定义参数问题，不知道有大神不

[hondely]

首先我的demo是已经调试好的，没有问题
接着我自己自定义了一个表单网页，用来提交total_fee以及其他参数的

<form action="http://www.test.cn/Wxpay/example/jsapi.php"  method="post">
    <input id="total_fee" value="55"></input>
    <input type="submit"/>
</form>

然后在jsapi.php中得到total_fee

$curFee=$_POST["total_fee"];
$tools = new JsApiPay();
$openId = $tools->GetOpenid($curFee);//$curFee传递给GetOpenid()函数进而传递给STATE

public function GetOpenid($total_fee)
	{
		//通过code获得openid
		if (!isset($_GET['code'])){
		//触发微信返回code码
		$baseUrl = urlencode('http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'].$_SERVER['QUERY_STRING']);
		$url = $this->__CreateOauthUrlForCode($baseUrl);
		$state=json_encode(array(
               "total_fee"=>"$total_fee"
            ));
		$url=str_replace("STATE",$state,$url);
		Header("Location: $url");
			exit();
		} else {
			//获取code码，以获取openid
		    $code = $_GET['code'];
		    $openid = $this->getOpenidFromMp($code);
                   $state=$_GET['state'];
                   $state=str_replace("\\","",$state);
                  $param=json_decode($state,true);
                  $state["total_fee"]=$param['total_fee']*100;
			return $openid;
		}

但是获得的total_fee始终是null，

URL解码后是这样的 https://open.weixin.qq.com/connect/oauth2/authorize?appid=wxe688d529fee63f02&redirect_uri=http://www.test.cn/Wxpay/example/jsapi.php&response_type=code&scope=snsapi_base&state={"total_fee":""}#wechat_redirect 难道是我第一个$curFee没有post得到数据吗？？？？

还是自己动手丰衣足食啊，post没有传值过去，把下面的id改为name 问题解决了

<form action="http://www.test.cn/Wxpay/example/jsapi.php"  method="post">
    <input id="total_fee" value="55"></input>
    <input type="submit"/>
</form>
