表单提交后，PHP重定向到另一个页面

Question

我已经阅读了所有有关将标头插入php表单文件中以便在提交表单后将用户重定向到另一个URL的文章-但我不知道该怎么做。下面是我的代码。您能告诉我在哪里放置标题/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页面吗？

    <?php

    if(isset($_POST['email'])) {

    // EDIT THE 2 LINES BELOW AS REQUIRED

    $email_to = "[e-mail]";

    $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

    $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.<br />';

  }

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

    $error_message .= 'The Last Name you entered does not appear to be valid.<br />';

  }  

    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';

<?php

}

?>

之后 @mail($email_to, $email_subject, $email_message, $headers);header('Location: nextpage.php');请注意，您将永远不会看到“感谢您订阅我们的邮件列表”那应该在下一页上，如果您回显任何文本，您将得到一个错误，因为标头已经被创建，如果您要重定向，则永远不会返回任何文本，甚至也不是空格！
