Php 成功注册时无法重定向
php
Php 成功注册时无法重定向,php,Php,我的剧本到底出了什么问题。我对它进行了测试，但每次成功注册似乎都不会将我重定向到register_success.php。它与这个register.phpheader（'Location:./register_success.php'）放在同一个文件夹下是我的位置问题吗？我尝试了header（'Location:register_success.php'）也不起作用 <!doctype html> <html> <head> <meta charset=

无标题文件
开始发送HTTP正文后，无法发送HTTP标头
代码的第一行是内容（doctype），因此在第一行触发HTTP主体
你应该看看
警告：无法修改标题信息-标题已发送
如果要重定向，则不要先发送文档

另一方面，尽管浏览器擅长从错误中恢复，HTTP规范要求位置标头具有绝对URI，而不是相对URI。
在成功时尝试重定向（使用。/
）
也可以使用exit在标题之后（“位置：”）
如果您的展位将文件保存在同一文件夹中，则可以使用此代码
<?php
header('Location:register_success.php');
?>



我已经对它进行了测试，它对我来说运行正常
发现位于psl-config.php
中的错误不应该存在
<?php
/**
 * These are the database login details
 */  
define("HOST", "localhost");     // The host you want to connect to.
define("USER", "xxxxx");    // The database username. 
define("PASSWORD", "xxxxx");    // The database password. 
define("DATABASE", "xxxx");    // The database name.
define("CAN_REGISTER", "any");
define("DEFAULT_ROLE", "member"); 
define("SECURE", FALSE);    // FOR DEVELOPMENT ONLY!!!!
?>
</body>
</html>


um。。我没有读过你的代码，但是，有什么错误吗？调试提示，尝试使用分治方法。注释大部分代码，并尝试在未注释的代码之后回显“something”
。如果它输出某个东西
，则没有问题。如果它没有输出something
错误在上面。你确定你的代码到达了执行重定向的行吗？你已经将html输出到客户端，重定向发生得太晚了。如果（！$insert\U stmt->execute（））{header，请尝试在else中重定向此语句（'Location:../error.php？err=Registration failure:INSERT'）；}
@BrianCoolidge页面上显示的无错误显示为空白，在代码中添加了error\u reporting。他说它与register.php放在同一文件夹下。
<?php
/**
 * These are the database login details
 */  
define("HOST", "localhost");     // The host you want to connect to.
define("USER", "xxxxx");    // The database username. 
define("PASSWORD", "xxxxx");    // The database password. 
define("DATABASE", "xxxx");    // The database name.
define("CAN_REGISTER", "any");
define("DEFAULT_ROLE", "member"); 
define("SECURE", FALSE);    // FOR DEVELOPMENT ONLY!!!!
