单击提交页面后，我想重定向到下一页，但出现以下错误：

警告：无法修改标头信息 - 标头已由第 70 行 C:\xampp\htdocs\P_details.php 中的（输出开始于 C:\xampp\htdocs\forms\P_details.php:80）发送

以下是 P_details.php 上的 php 代码

要么ob_start()在页面顶部和ob_end_flush()底部调用，要么在你之前的页面上不回显任何内容header()

当您在前往另一个页面之前将任何输出回显到浏览器时，就会出现该错误。

检查你的包含，并确保你没有在任何地方做回声。

我将行 include 'forms/P_details.php' 移到标题语句下方

<?php

//connect to connect to the database and initialize all functions
include 'scripts/functions/init.php';
include 'html/head.php';
include 'html/page_title.php';
include 'html/top_menu.php';
include 'titles/P_details.php';

//Generate a random Personid
$Personid = rand(1,9999999);
$_SESSION['Personid'] = $Personid;
//Carry over the Jobid to this page
$Jobid = $_SESSION['SESS_MEMBER_JOB'];

if(empty($_POST)=== false)
    {
        $R_fields = array('Title','Surname','Forename','IdentityNumber','Gender','Race','Nationality');
        foreach($_POST as $key=>$value)
        {
            if (empty($value) && in_array($key,$R_fields)=== true)
                {
                    $errors[] = 'fields marked with (*) are required';
                    break 1;
                }
        }

        if(empty($errors)=== true)
            {

                if($_POST['title'] == '-Select-')
                    {
                        $errors[] ='Please select Title';
                    }
                if($_POST['Gender'] == '-Select-')
                    {
                        $errors[] ='Please select Gender';
                    }
                if($_POST['Race'] == '-Select-')

                    }

            }

    }



    if(empty($_POST) === false && empty($errors)=== true)
        {
            //submit personal details
            $personal_details = array(

header('Location:Address_insert.php'); 在任何输出之前。

可能您包含的文件包含任何输出？

include 'html/head.php';
include 'html/page_title.php';
include 'html/top_menu.php';
include 'titles/P_details.php';

或者

include 'forms/P_details.php';

任何输出只能在之后插入header('Location:Address_insert.php');
