Question

我使用提供此错误的第三方API作为结帐流程的一部分使用了网页：

警告：session_start（）[function.session-start]：无法发送会话cookie - 已经在第1行的/upgrades/upgradevip.php中发送的（在/upgrades/upgradevip.php:1中开始输出）的头文件

警告：session_start（）[function.session-start]：无法发送会话缓存限制器 - 已在第1行的/upgrades/upgradevip.php中发送的标头（在/upgrades/upgradevip.php：1处开始输出）

我需要更改php代码中的哪一行才能使其正常工作？

以下是代码：

<?php session_start();

include('./includes/config.php');
include('./includes/functions.php');
include('./lib/recurly.php');

$message='';

// Required for the API
Recurly_Client::$apiKey = API_KEY;
// Optional for Recurly.js:
Recurly_js::$privateKey = PRIVATE_KEY;

$firstname=get_querystring_var_val('firstname');
$lastname=get_querystring_var_val('lastname');
$email=get_querystring_var_val('email');
$phonenumber=get_querystring_var_val('phonenumber');
$brand=get_querystring_var_val('brand');
$zip=get_querystring_var_val('zip');


if(isset($_POST['process']) && $_POST['process'] =='1'){

    /*

    $account_code=$acc;

    if($account_code!=''){

        /*

        */

        $transaction = new Recurly_Transaction();
        $transaction->description = $upsell_description;

        $transaction->currency = CURRENCY_CODE;

        $account = new Recurly_Account();
        $account->account_code = $account_code;

        $billing_info = new Recurly_BillingInfo();

            $success=true;
        }catch(Exception $e){

        }


        if($success){
            /*
            * set one time transaction details in session
            */
            try {
                $transactions = Recurly_TransactionList::getForAccount($account_code);
                foreach ($transactions as $transaction) {
                  //print "$subscription\n";
                  //echo '<br/><br/>';
                  $_SESSION['onetime_receipt']=$transaction->uuid;
                }
            } catch (Recurly_NotFoundError $e) {
                //$message= "Transaction not found" . $e;
            }
            header('Location: /congratulations2deff5-us.php?account='. $acc.'&plan=' . $plan.'&subid=' . $subid.'&aff='.$aff.'&firstname='.$firstname.'&lastname=' .$lastname. '&email=' .$email .'&phonenumber='.$phonenumber.'&brand=' . $brand . '&zip=' . $zip);
            exit;

        }else{

            $message='Transaction could not be processed';
        }
    }else{
        $message='There was problem processing your request.';
    }

}

Answer 1

如果您在开始<?php标记之前确实有空格，请将其删除。

Answer 2

试试这样：

<?php
session_start();

并删除之前的前导空格
