How to redirect to success / fail pages after php form submission?
提问by Chris
I have successfully integrated the following form submission code into my site, and it works great. However I would like to have the code redirect the user to one page if the form submission is successful, and a different page if it fails. How could I adapt the following code to do that? It's really starting to get on my nerves! :-P
我已成功将以下表单提交代码集成到我的网站中，并且效果很好。但是，如果表单提交成功，我希望代码将用户重定向到一个页面，如果提交失败，则将用户重定向到另一个页面。我怎样才能修改以下代码来做到这一点？我真的开始紧张了！:-P
<?php
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$enquiry = $_POST['enquiry'];
$formcontent=" From: $name \n Phone: $phone \n Message: $enquiry";
$recipient = "[email protected]";
$subject = "Contact Form";
$mailheader = "From: $email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
echo "Thank You!";
?>
EDIT:
编辑：
Ok I have changed the code to:
好的，我已将代码更改为：
<?php
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$enquiry = $_POST['enquiry'];
$formcontent=" From: $name \n Phone: $phone \n Message: $enquiry";
$recipient = "[email protected]";
$subject = "Contact Form";
$mailheader = "From: $email \r\n";
if(mail($recipient, $subject, $formcontent, $mailheader)){
header("Location: mailer-success.htm");
}else{
header("Location: mailer-fail.htm");
}
exit;
?>
This works however it never goes to the fail page. I'm guessing that's because the email is always sent even if fields are empty. I have jquery verification in place (which I have disabled for testing purposes) but that obviously only works for users with javascript enabled. How could I alter the code to only show the success page if the form fields contain data? Any help is appreciated.
这有效，但是它永远不会进入失败页面。我猜这是因为即使字段为空，也会始终发送电子邮件。我有 jquery 验证（为了测试目的我已经禁用了它），但这显然只适用于启用了 javascript 的用户。如果表单字段包含数据，我如何更改代码以仅显示成功页面？任何帮助表示赞赏。

add a redirect to the page:
添加重定向到页面：
// Test to see if variables are empty:
if(!empty($name) && !empty($email) && !empty($phone) && !empty($enquiry)){
// Test to see if the mail sends successfully:
if(mail($recipient, $subject, $formcontent, $mailheader)){
header("Location: success.php");
}else{
header("Location: error.php");
}
}else{
header("Location: back_to_form.php");
}

mail function returns true/false when succeeds/fails. So it's rather simple:
邮件函数在成功/失败时返回真/假。所以它相当简单：
if (mail($recipient, $subject, $formcontent, $mailheader)) {
header('location: success.php');
} else {
header('location: fail.php');
}

Add
添加
header("Location: successpage.html");
to the bottom of your code and remove echo "Thank you!";
到代码底部并删除 echo "Thank you!";

Rather than send the client a redirect, resulting in another call to your web server, I believe a better way of doing this would be to use a PHP include.
而不是向客户端发送重定向，导致另一个调用您的 Web 服务器，我相信这样做的更好方法是使用 PHP 包含。
if (mail($recipient, $subject, $formcontent, $mailheader))
include 'success.php';
else
include 'fail.php';

Get rid of the echo and then use a header:
摆脱回声，然后使用标题：
header("Location: success.php");
If it fails, redirect to error.php
如果失败，重定向到 error.php
header("Location: error.php");
If you want to go to the page the form was on, but show an error or success message, do this:
如果您想转到表单所在的页面，但显示错误或成功消息，请执行以下操作：
header("Location: original.php?status=error")
Or change error to success if appropriate, you can then use $_GET['status']to determine whether or not the form failed / succeeded.
或者在适当的情况下将错误更改为成功，然后您可以使用它$_GET['status']来确定表单是否失败/成功。

if (failure) {
header("Location: success.php");
exit;
} else if (success) {
echo "thank you";
}
