Question

我想将mail.php脚本与感谢页面分开，并在脚本运行后重定向。我的以下脚本导致错误 - 已发送标头...

我需要更改什么才能使标题调用正常工作？

 <?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 />";

你有很多额外的空间，还有HTML评论。取出除开始和结束PHP大括号之外的所有内容，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重定向。您可能希望以某种方式保存错误（$ _SESSION或$ _GET变量）并重定向到上一页。
