我知道代码很长......但我希望我正在寻找的解决方案简单快捷。所以我在我的订单上有一个会议。我有两种形式，这取决于该人是否登录。首先，如果用户是登录的话，那就完成了所有这些（我知道代码不完美，但它对我有用）。问题： 下订单后如何将用户重定向到他们的帐户？我在} else {...没有用之前尝试了头功能，把我带到帐户页面。我无法在线找到代码，因为他们的表单都在html内部，而不是在php中，所以标题不起作用。任何建议???

答案 0 :(得分：2)
您无法向浏览器写任何内容并期望header功能正常工作。为了设置标题，响应正文必须为空。
所以我建议做类似的事情：
if(isset($_POST['submit'])){
// do the INSERT and whatnot
// when finished call the header function
header("Location: my_custom_page.php");
}
else{
// output the form, javascript and what you need
}
因此，第一次加载页面时，它将进入else语句，因为您没有POST数据。这将打印出表单和验证JavaScript。提交表单后，请求将进入if，并下订单，然后重定向客户端。
同样，在if声明中，您不能进行任何echo。一个非常糟糕的替代方案，就是回应一个重定向的小javascript（我不推荐这个。永远）：
<script>window.location.href = 'my_custom_page.php';</script>

以下是我将如何构建流程：
请记住，即使一个字符已输出或呈现给页面，也无法更改页眉。
，您应该选择使用其他邮件传递方式，因为mail()邮件将保证到垃圾邮件文件夹，因为它使用发件人标头中的服务器信息。 / p>

如果你想使用JS，你可以随时在html中执行：
<script>
window.location.href = <?php echo $url; ?>
</script>
