这个问题以前有人问过，但不是在这种情况下。这些消息通过，但不是重定向它给我一个错误。我在其他网站上使用相同的表单提交代码，效果很好 在
标题（'location:…'）后使用exit当您重定向到某个页面时
像
还有，*不要打印任何先入为主的内容*
例如，您在php
中使用html
的注释
删除上面的行或使其成为php注释
//在此处包含您自己的成功html
将header命令放在第一个PHP标记中
@mail($email_to, $email_subject, $email_message, $headers);
header("Location: thankyou.html");
?>
试试这个：
<?php

这是一个标题周围打开php标记前的空白问题。我必须假设是我挑剔的服务器。我听说过空白区问题，但我从未遇到过，而且我已经多次使用此表单
谢谢大家帮助我。你做错了。您不能在输出某些内容（甚至不是空格）后设置标题。只需在顶部设置标题，就像
<?php
header("Location: thankyou.html");
希望这对您有所帮助第144行？？有数百个问题解释了导致错误的原因以及如何修复错误。发布前是否尝试过搜索？不要在页眉（）上方添加HTML输出<代码>header（'location:…）window.location.replace("http://example.com/thankyou.html");
