表单提交后如何重定向？ [英] How to redirect after form submit?

问题描述

我有一个带有提交按钮的基本反馈表。


在发送之后单击按钮，我希望用户被重定向到

不同的页面，上面写着您的消息已被发送。


我如何这样做了吗？


我尝试过使用：


header（" Location：http：//www.mysite.com/ send-confirm.php"）;


但这里是我得到的错误：


警告：无法添加标题信息 - 标题已经发送了（输出开始

at ...


这里是代码：


< ; form action ="

<？php

$ message = trim（$ _ REQUEST [''message'']）;

$ email_address = trim（$ _ REQUEST [''email_address'']）;

if（空（$ message）||空（$ email_address））

{

$ valid_message = false;

}

else

{

mail（"我的电子邮件地址，反馈表单，消息，来自：
$ email_address"）;

$ valid_messa ge = true;

}

？>"

< input name =" email_address"类型= QUOT;文本" size =" 30" />< br />

< textarea name =" message"行= QUOT; 12英寸cols =" 23">< / textarea>< br />

< input type =" submit" value =" Send">

< / form>

<？php

if（$ valid_message）

{

echo"有效消息" ;;

header（" Location：http：//www.mysite.com/send-confirm.php" ）;

退出（）;

}

其他

{

echo 无效消息;

}

如何在用户点击发送按钮后重定向？


提前致谢。

解决方案

message = trim（

< blockquote> _REQUEST [''message'']）;

email_address = trim（

I have a basic feedback form with a submit button.

After the "send" button is clicked, I want the user to be redirected to a
different page that says "Your message has been sent."

How do I do this?

I''ve tried using:

header("Location:http://www.mysite.com/send-confirm.php");

But here''s the error I get:

Warning: Cannot add header information - headers already sent by (output started
at ...

Here''s the code:

<form action= "
<?php
$message = trim($_REQUEST[''message'']);
$email_address = trim($_REQUEST[''email_address'']);
if (empty($message) || empty($email_address))
{
$valid_message = false;
}
else
{
mail( "my email address", "feedback form", $message, "from:
$email_address" );
$valid_message = true;
}
?>"
<input name="email_address" type="text" size="30"/><br />
<textarea name="message" rows="12" cols="23"></textarea><br />
<input type="submit" value="Send">
</form>
<?php
if ($valid_message)
{
echo "valid message";
header("Location:http://www.mysite.com/send-confirm.php");
exit();
}
else
{
echo "invalid message";
}
?>

How do I redirect after the user clicks the send button?

Thanks in advance.
