Question

我已经建立了一个注册表单页面。它允许您注册帐户并将其存储在数据库中。

最初，它将任何错误发回到同一页面（称为index.php）

然而，在进入注册页面之前，我想向用户展示一个＆＃34;我已经拥有一个帐户＆＃34;按钮和＆＃34;创建新帐户＆＃34;按钮。这是因为该网站适合儿童，我不想在同一页面上加载大量文字。

所以，如果你去这里，你会发现有两种选择。这些通过AJAX以相关的形式加载到div login-register-wrapper中。单击一个，它将加载register-form.php，另一个是login-form.php（当前不工作）

我遇到的问题是，在验证时，它会回发到index.php

header('Location: index.php');

因此，如果您没有输入用户名，而不是发布错误，则会将您带回第一页...

如何使用AJAX使其能够在register-form.php文件中发布？

这是完整的注册页面代码：

<?php
    session_start();
    require 'functions.php';

    if(isset($_POST['sign-up'])){

        // username
        if (isset($_POST['username'])){
            $username = mysql_real_escape_string(trim($_POST['username']));
            $_SESSION['status']['register']['username'] = $username;

            if(strlen($username) > 3){
                    if(strlen($username) < 31){
                        if(user_exists($username) === true){
                            $_SESSION['status']['register']['error'][] = 'That username is already taken. Sorry, please try again with a different username.';
                        } else{
                            // passed
                            // continue

如果主页由AJAX请求产生，则标题无法重定向主页面。相反，您可以使用AJAX回调来解释页面结果并相应地重定向页面。干净的方法是始终返回JSON结果。然后，这可能包含类似redirect的字段，其字段对应于用户应重定向到的页面。

您可以使用json_encode将PHP数组转换为JSON结果。如果你正在使用jQuery，parseJSON是一个很好的解析JSON代码的函数。检索到redirect值后，您可以使用location.window = redirectUrl;重定向用户。

使用PHP中的头函数通过AJAX重新加载页面
