Question

我设置了一个简单的注册表单，将详细信息发送到我的函数以将数据放入数据库中我希望页面重定向到成功页面...

这在我的本地服务器上非常出色，但当我将其上传到我的实时服务器时，它只是不重定向

无效的重定向是在第65行:)它只是重定向到register.php？success

感谢任何帮助。我见过一些人有同样的问题，但他们的解决方案对我不起作用：（

所有其他标头位置都有效。只是这个不会：@

    $required_fields = array('username', 'password', 'password_again', 'first_name', 'last_name', 'email');
    foreach ($_POST as $key => $value) {
        if (empty($value) && in_array($key, $required_fields) === true) {
            $errors[] = 'You appear to have missed something out, all fields are required.';
            break 1;

Answer 1

最有可能的是，输出缓冲区在开发环境中处于打开状态，在实时环境中处于关闭状态。此外，必须在实时环境中关闭向用户显示错误，否则将在浏览器中显示确切的错误（标题之前开始输出）。

检查你的ini文件中的内容：http://php.net/manual/en/outcontrol.configuration.php

请记住，在发送任何实际输出之前，必须通过普通HTML标记，文件中的空行或PHP来调用header（）。使用include（）或require（），函数或其他文件访问函数读取代码是一个非常常见的错误，并且在调用header（）之前输出空格或空行。使用单个PHP / HTML文件时存在同样的问题。
