javascript - "Submit"按钮发送邮件但不重定向？

Question

这个脚本让我抓狂。这是一个简单的提交表格。我单击“提交”按钮，包含所有提交信息的电子邮件完美生成。

但我无法获得将我重定向到“谢谢”页面的按钮。

我尝试过 PHP，我尝试过 Javascript，我什至尝试过老式的元重定向。没有任何效果。

// 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);  

header("location:http://amvleague.vitaminh.info/thankyou.html")
}

die();
?>

我尝试将“标题”部分放在文档的顶部。我尝试将其更改为:

echo '<script>document.location="page2.html"; </script>';

我使用此脚本生成了如此多的电子邮件，以至于 gmail 现在将它们全部发送到垃圾邮件。而且我无法让该死的东西重定向。

如果有人能在我把眼睛挖出来之前提供帮助，我将非常感激。 ^_^;;

编辑:我已经尝试了你们建议的一切。就好像脚本完全拒绝执行 mail 命令之后的任何内容。难道这其中有什么原因吗？

编辑2:仍然没有任何效果。

这是整个脚本(经过 Rolen Koh 的修改)。这里是否隐藏了一些东西，阻止脚本访问邮件标记之后的任何内容？

        // your error code can go here
        echo "We are very sorry, but there were error(s) found with the form     you submitted. ";

Answer 1

您可以使用 header() 函数发送新的 HTTP header ，但这必须在任何 HTML 或文本之前发送到浏览器(例如，在 <!DOCTYPE ...> 声明之前)。

试试这个，这就是我正在使用的

 function redirect($url){
    if (headers_sent()){
      die('<script type="text/javascript">window.location.href="' . $url . '";</script>');
    }else{
      header('Location: ' . $url);
      die();
    }    
}
