Question

这是我在Stackoverflow中的第一篇文章。到目前为止，我从本网站获得了最佳解决方案，但没有在本网站发布任何问题。

这是关于Paypal与我网站的整合。我从最近1个月开始挣扎。我试过很多方面但没有成功。来到我的问题，我没有得到Paypal的有效回复。有时TXN Id是空的，有时它正在工作。请检查以下代码并纠正我。

这是Paypal的最终查询字符串

   business=xxxxxxxxxxxx&item_name_1=Dell_laptop%29&amount_1=50&item_number_1=10&return=http%3A%2F%2Fwww.xxxx.com%2Fpayments.php&cancel_return=http%3A%2F%2Fwww.xxxxxxxx.com%2Fpayment-not-sucess.php¤cy_code=CAD¬ify_url=http%3A%2F%2Fwww.xxxxxxx.com%2Fpayments.php&no_note=0&country=USA&cmd=_cart&upload=1

Payments.php

        if (!isset($_GET['tx']) && !isset($_GET['st'])){

        $header = array("Content-type: text/html", "multipart/form-data");

        $querystring = "business=".urlencode($paypal_email)."&";

        $querystring .= "item_name_1=".urlencode($exam_name_1)."&";
        $querystring .= "amount_1=".urlencode($amount_1)."&";
        $querystring .= "item_number_1=".urlencode($item_number_1)."&";

        if(($amount_2>0) && ($item_number_2 !='')){
        $querystring .= "item_name_2=".urlencode($exam_name_2)."&";
        $querystring .= "amount_2=".urlencode($amount_2)."&";
        $querystring .= "item_number_2=".urlencode($item_number_2)."&";
        }

        $querystring .= "return=".urlencode(stripslashes($return_url))."&";
        $querystring .= "cancel_return=".urlencode(stripslashes($cancel_url))."&";

        //$querystring .= "rm=".urlencode($rm)."&";
        $querystring .= "currency_code=".urlencode($currency_code)."&";
        $querystring .= "notify_url=".urlencode($notify_url)."&";
        $querystring .= "no_note=".urlencode($no_note)."&";
        $querystring .= "country=".urlencode($country)."&";
        $querystring .= "cmd=".urlencode($cmd)."&";
        $querystring .= "upload=".urlencode($upload);
        header("Location: http://www.paypal.com/cgi-bin/webscr?".$querystring);

       }
        else{    // Response from Paypal................
        echo $payment_gross=$_REQUEST['amt']; 
        echo $txn_id=$_REQUEST['tx'];
        echo $payment_status=$_REQUEST['st'];

            header("Location: xxxx.php");

             }

Paypal设置：

自动返回：开启

返回网址：http://www.xxxxxxx.com/payments.php

通知网址：http://www.xxxxxxx.com/payments.php

PDT：on

IPN：已启用..

为了在成功付款后获得PayPal的正确回复，您必须在阵列中提及您发送给PayPal的成功网址

 if (!isset($_GET['tx']) && !isset($_GET['st'])){

    $header = array("Content-type: text/html", "multipart/form-data");

    $querystring = "business=".urlencode($paypal_email)."&";

    $querystring .= "item_name_1=".urlencode($exam_name_1)."&";
    $querystring .= "amount_1=".urlencode($amount_1)."&";
    $querystring .= "item_number_1=".urlencode($item_number_1)."&";

    if(($amount_2>0) && ($item_number_2 !='')){
    $querystring .= "item_name_2=".urlencode($exam_name_2)."&";
    $querystring .= "amount_2=".urlencode($amount_2)."&";
    $querystring .= "item_number_2=".urlencode($item_number_2)."&";
    }

    $querystring .= "return=".urlencode(stripslashes($return_url))."&";
    $querystring .= "cancel_return=".urlencode(stripslashes($cancel_url))."&";

    //$querystring .= "rm=".urlencode($rm)."&";
    $querystring .= "currency_code=".urlencode($currency_code)."&";
    $querystring .= "notify_url=".urlencode($notify_url)."&";
    //Added Line
    $querystring .= "success_url=".urlencode($notify_url)."&";
    $querystring .= "no_note=".urlencode($no_note)."&";
    $querystring .= "country=".urlencode($country)."&";
    $querystring .= "cmd=".urlencode($cmd)."&";
    $querystring .= "upload=".urlencode($upload);
    header("Location: http://www.paypal.com/cgi-bin/webscr?".$querystring);

   }
    else{    // Response from Paypal................
    echo $payment_gross=$_REQUEST['amt']; 
    echo $txn_id=$_REQUEST['tx'];
    echo $payment_status=$_REQUEST['st'];

        header("Location: xxxx.php");

         }
