PHP Redirect to another page after form submit
提问by user2494737
I have read all your posts about inserting headers into a php form file in order to redirect the user to another URL AFTER the form is submitted - but I can't figure out how to do it. Below is my code. Can you show me where to put the header/redirect so that the information gets e-mailed and then the user goes to another html page?
我已经阅读了您关于将标题插入 php 表单文件以便在提交表单后将用户重定向到另一个 URL 的所有帖子 - 但我不知道该怎么做。下面是我的代码。你能告诉我把标题/重定向放在哪里，以便信息通过电子邮件发送，然后用户转到另一个 html 页面吗？
<?php
if(isset($_POST['email'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "[email protected]";
$email_subject = "Mailing List Form";
function died($error) {
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you
submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
if(!isset($_POST['first_name']) ||
!isset($_POST['last_name']) ||
!isset($_POST['email']) ||
!isset($_POST['telephone']) ||
!isset($_POST['company']) ||
!isset($_POST['street']) ||
!isset($_POST['city']) ||
!isset($_POST['state']) ||
!isset($_POST['zip'])) {
died('We are sorry, but there appears to be a problem with the form you
submitted.');
}
$first_name = $_POST['first_name']; // required
$last_name = $_POST['last_name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // required
$company = $_POST['company']; // required

$error_message = "";
$string_exp = "/^[A-Za-z0-9 .'-]+$/";
if(!preg_match($string_exp,$first_name)) {
$error_message .= 'The First Name you entered does not appear to be valid.<br />';

if(!preg_match($string_exp,$city)) {

if(!preg_match($string_exp,$state)) {
$error_message .= 'The State you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$zip)) {
$error_message .= 'The Zip Code you entered does not appear to be valid.<br />';
}
if(strlen($error_message) > 0) {
died($error_message);
}
$email_message = "Response from Mailing List Page. Please enter in database.\n\n";
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "First Name: ".clean_string($first_name)."\n";
$email_message .= "Last Name: ".clean_string($last_name)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";

// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);
?>
<!-- include your own success html here -->
Thanks for subscribing to our mailing list
<?php
}
?>

Right after @mail($email_to, $email_subject, $email_message, $headers);
紧随其后 @mail($email_to, $email_subject, $email_message, $headers);
header('Location: nextpage.php');
Note that you will never see 'Thanks for subscribing to our mailing list'
请注意，您永远不会看到“感谢您订阅我们的邮件列表”
That should be on the next page, if you echo any text you will get an error because the headers would have been already created, if you want to redirect never return any text, not even a space!
那应该在下一页，如果你回显任何文本，你会得到一个错误，因为标题已经被创建，如果你想重定向永远不会返回任何文本，甚至一个空格！

First give your input type submit a name, like this name='submitform'.
首先给你的输入类型提交一个名字，像这样name='submitform'。
and then put this in your php file
然后把它放在你的php文件中
if (isset($_POST['submitform']))
{
?>
<script type="text/javascript">
window.location = "http://www.google.com/";
</script>
<?php
}
Don't forget to change the url to yours.
不要忘记将网址更改为您的网址。

If your redirect is in PHP, nothing should be echoed to the user before the redirect instruction.
如果您的重定向是在 PHP 中，则在重定向指令之前不应向用户回显任何内容。
See headerfor more info.
有关更多信息，请参阅标题。
Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP
请记住，header() 必须在发送任何实际输出之前调用，无论是通过普通的 HTML 标记、文件中的空行还是来自 PHP
Otherwise, you can use Javascript to redirect the user.
否则，您可以使用 Javascript 重定向用户。
Just use
只需使用
window.location = "http://www.google.com/"

You can include your header function wherever you like, as long as NO html and/or text has been printed to standard out.
你可以在任何你喜欢的地方包含你的标题功能，只要没有 html 和/或文本被打印到标准输出。

I see in your code that you echo()out some text in case of error or success. Don't do that: you can't. You can only redirect OR show the text. If you show the text you'll then fail to redirect.
我在您的代码中看到，echo()如果出现错误或成功，您会输出一些文本。不要那样做：你不能。您只能重定向或显示文本。如果您显示文本，您将无法重定向。
回答by Frildoren
Whenever you want to redirect, send the headers:
每当您想重定向时，请发送标头：
header("Location: http://www.example.com/");
Remember you cant send data to the client before that, though.
请记住，在此之前您不能向客户端发送数据。

Once had this issue, thought it reasonable to share how I resolved it;
曾经遇到过这个问题，认为分享我如何解决它是合理的；
I think the way to do that in php is to use the header function as:
我认为在 php 中这样做的方法是使用 header 函数作为：
header ("Location: exampleFile.php");
You could just enclose that header file in an if statement so that it redirects only when a certain condition is met, as in:
您可以将该头文件包含在 if 语句中，以便它仅在满足特定条件时重定向，如下所示：
if (isset($_POST['submit'])){ header("Location: exampleFile.php") }
Hope that helps.
希望有帮助。
