重新调换mail.php脚本

Question

我想将mail.php脚本与“谢谢”页面分开，并在脚本运行后将其重定向到那里。 我的以下脚本导致错误-标头已发送...

我需要更改什么才能使标头调用正常工作？

 <?php 
session_start();
if(isset($_SESSION['captcha_value']) && isset($_POST['text3'])){
  if($_SESSION['captcha_value'] != $_POST['text3']){
    echo "invalid captcha";
    die();  
  }
}else{
  echo "invalid captcha";
  die();
}
?>





<?php require_once('../inc/header-scripts.php'); ?>

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

    // EDIT THE 2 LINES BELOW AS REQUIRED
    $email_to = "me@mysite.com";
    $email_subject = "NEW MESSAGE";


    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($_POST['email']) ||
        !isset($_POST['telephone']) ||
        !isset($_POST['comments']))


        {
        died('We are sorry, but there appears to be a problem with the form you submitted.');      
    }

    $first_name = $_POST['first_name']; // required

    $email_from = $_POST['email']; // required
    $telephone = $_POST['telephone']; // not required
    $comments = $_POST['comments']; // required

    $error_message = "";
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
  if(!preg_match($email_exp,$email_from)) {
    $error_message .= 'The Email Address you entered does not appear to be valid.<br />';
  }
    $string_exp = "/^[A-Za-z .'-]+$/";
  if(!preg_match($string_exp,$first_name)) {
    $error_message .= 'The First Name you entered does not appear to be valid.<br />';
  }

  if(strlen($comments) < 2) {
    $error_message .= 'The Comments you entered do not appear to be valid.<br />';
  }



  if(strlen($error_message) > 0) {
    died($error_message);
  }
    $email_message = "";

    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";

    $email_message .= "Email: ".clean_string($email_from)."\n";
    $email_message .= "Telephone: ".clean_string($telephone)."\n";
    $email_message .= "Comments: ".clean_string($comments)."\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 -->



<?php
}

<?php
header('location: thank-you.php');
?>

您还有很多额外的空间以及HTML注释。 除了打开和关闭PHP花括号外，取出所有内容，并删除HTML注释行。 请注意，如果验证码失败，它将保留在该页面上而不进行重定向。 您可能希望以某种方式保存错误（$ _SESSION或$ _GET变量），然后重定向到上一页。

session_start();
if(isset($_SESSION['captcha_value']) && isset($_POST['text3'])){
  if($_SESSION['captcha_value'] != $_POST['text3']){

  }
}else{
  echo "invalid captcha";
  die();
}
