我想在点击提交页面后重定向到下一页，但是我收到以下错误：

警告：无法修改标题信息 - 已在第70行的C：\ xampp \ htdocs \ P_details.php中发送的标题（输出从C：\ xampp \ htdocs \ forms \ P_details.php：80开始）

以下是P_details.php上的php代码

请协助

Answer 1

要么在页面顶部调用ob_start()，在底部调用ob_end_flush()，要么在header()

之前回显页面上的任何内容

Answer 2

当您在前往另一个页面之前将任何输出回显到浏览器时，会出现该错误。

检查您的包含，并确保您没有在任何地方做回声。

Answer 3

我在标题声明

下面移动了包含'forms / P_details.php'的行

<?php

if(empty($_POST)=== false)
    {
        $R_fields = array('Title','Surname','Forename','IdentityNumber','Gender','Race','Nationality');
        foreach($_POST as $key=>$value)

        include 'forms/P_details.php';

Answer 4

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

包含的文件可能包含任何输出吗？

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';

任何可能仅在header('Location:Address_insert.php');

之后插入的输出
