PHP在表单提交后重定向到另一个页面-Java 学习之路

我已经阅读了有关将 Headers 插入到php表单文件中的所有帖子，以便在提交表单后将用户重定向到另一个URL - 但我无法弄清楚如何执行此操作 . 以下是我的代码 . 你能告诉我在哪里放置 Headers /重定向，以便通过电子邮件发送信息，然后用户转到另一个html页面？

<?php
    if(isset($_POST['email'])) {

    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "pecraig@moneymovers.com";
    $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.

";
        echo $error."

";
        echo "Please go back and fix these errors.

";
        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
    $street = $_POST['street']; // required
    $city = $_POST['city']; // required
    $state = $_POST['state']; // required
    $zip = $_POST['zip']; // required

    $error_message = "";
    $string_exp = "/^[A-Za-z0-9 .'-]+$/";
  if(!preg_match($string_exp,$first_name)) {
    $error_message .= 'The First Name you entered does not appear to be valid.
';
  }
  if(!preg_match($string_exp,$last_name)) {
    $error_message .= 'The Last Name you entered does not appear to be valid.
';
  }  
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
  if(!preg_match($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.
';
  }
  if(!preg_match($string_exp,$company)) {
    $error_message .= 'The Company you entered does not appear to be valid.
';
  }
  if(!preg_match($string_exp,$street)) {
    $error_message .= 'The Street you entered does not appear to be valid.
';
  }
  if(!preg_match($string_exp,$city)) {
    $error_message .= 'The City you entered does not appear to be valid.
';
  }
  if(!preg_match($string_exp,$state)) {
    $error_message .= 'The State you entered does not appear to be valid.
';
  }
  if(!preg_match($string_exp,$zip)) {
    $error_message .= 'The Zip Code you entered does not appear to be valid.
';
  }
  if(strlen($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";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Company: ".clean_string($company)."\n";
    $email_message .= "Street: ".clean_string($street)."\n";
    $email_message .= "City: ".clean_string($city)."\n";
    $email_message .= "State: ".clean_string($state)."\n";
    $email_message .= "Zip: ".clean_string($zip)."\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);

?>

您可以在任何位置包含 Headers 功能，只要没有打印到标准输出的HTML和/或文本 .

有关更多信息和用法：http://php.net/manual/en/function.header.php

我在您的代码中看到，如果出现错误或成功，您可以输出一些文本 . 唐't do that: you can' t . 您只能重定向或显示文本 . 如果您显示文本，则无法重定向 .

首先给你的输入类型提交一个名字，比如 name='submitform' .

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
    }
```
不要忘记将网址更改为您的网址 .

如果重定向是在PHP中，则在重定向指令之前不应向用户回显任何内容 .

有关详细信息，请参阅header .

请记住，必须在发送任何实际输出之前调用header（），无论是普通HTML标记，文件中的空行还是PHP

否则，您可以使用Javascript重定向用户 .

只是用
```
window.location = "http://www.google.com/"
```

在 @mail($email_to, $email_subject, $email_message, $headers); 之后
```
header('Location: nextpage.php');
```
请注意，您永远不会看到“感谢您订阅我们的邮件列表”

这应该是在下一页，如果你回显任何文本你会得到一个错误，因为 Headers 已经创建，如果你想重定向永远不会返回任何文本，甚至没有空格！

每当您想要重定向时，请发送 Headers ：
```
header("Location: http://www.example.com/");
```
但请记住，在此之前你无法向客户端发送数据 .

一旦遇到这个问题，我认为分享我如何解决它是合理的;

我认为在php中这样做的方法是使用头函数：
```
header ("Location: exampleFile.php");
```
您可以将该头文件包含在if语句中，以便仅在满足特定条件时重定向，如：
```
if (isset($_POST['submit'])){   header("Location: exampleFile.php")   }
```
希望有所帮助 .
