Question

在添加用户定义的字段时，Payumoney中出现CheckSum错误，尽管在添加之前定义完美。

我一直在当实习生，我的员工要求我建立一个支付网关。我以前工作过，但是在添加两个用户定义的字段时，它开始给我一个校验和错误。

<?php

$MERCHANT_KEY = "Key";
$SALT = "Salt";
// Merchant Key and Salt as provided by Payu.

$PAYU_BASE_URL = "https://sandboxsecure.payu.in";       // For Sandbox Mode
//$PAYU_BASE_URL = "https://secure.payu.in";            // For Production Mode
$succesURL="Success URL";
$failureURL="Fail URL";
$action = '';

$posted = array();
if(!empty($_POST)) {
    //print_r($_POST);
  foreach($_POST as $key => $value) {    
    $posted[$key] = $value; 

  }
}

$formError = 0;

if(empty($posted['txnid'])) {
  // Generate random transaction id
  $txnid = substr(hash('sha256', mt_rand() . microtime()), 0, 20);
} else {
  $txnid = $posted['txnid'];
}
$hash = '';
// Hash Sequence
$hashSequence = "key|txnid|amount|productinfo|firstname|email|udf1|udf2|udf3|udf4|udf5|udf6|udf7|udf8|udf9|udf10";
if(empty($posted['hash']) && sizeof($posted) > 0) {
  if(
          empty($posted['key'])
          || empty($posted['txnid'])
          || empty($posted['amount'])
          || empty($posted['firstname'])
          || empty($posted['email'])
          || empty($posted['phone'])
          || empty($posted['productinfo'])
          || empty($posted['surl'])
          || empty($posted['furl'])
          || empty($posted['service_provider'])
  ) {
    $formError = 1;
  } else {
    //$posted['productinfo'] = json_encode(json_decode('[{"name":"tutionfee","description":"","value":"500","isRequired":"false"},{"name":"developmentfee","description":"monthly tution fee","value":"1500","isRequired":"false"}]'));
    $hashVarsSeq = explode('|', $hashSequence);
    $hash_string = '';  
    foreach($hashVarsSeq as $hash_var) {
      $hash_string .= isset($posted[$hash_var]) ? $posted[$hash_var] : '';
      $hash_string .= '|';
    }

    $hash_string .= $SALT;


    $hash = strtolower(hash('sha512', $hash_string));
    $action = $PAYU_BASE_URL . '/_payment';
