【问题描述】：

我是 PHP 新手，所以请温柔一点。

我编写了一个网站，并添加了订阅时事通讯部分。用户在按下提交之前添加他们的姓名和电子邮件地址。我收到了电子邮件，所以大部分都在工作，但表格并没有让我回到网站的主页。谁能指出我哪里出错了？

提前致谢

网站上的代码是：

<form name="frmcontact" id="frmcontact" action="php/contact.php" method="post">
      <input id="name" name="name" type="text" value="Name"
      onblur="this.value=(this.value=='') ? 'Name' : this.value;"              onfocus="this.value=(this.value=='Name') ? '' : this.value;" />
 <input id="email" name="email" type="text" value="Email" 
 onblur="this.value=(this.value=='') ? 'Email' : this.value;" onfocus="this.value=(this.value=='Email') ? '' : this.value;" />
<input name="submit" id="send" type="submit" value="Message" />
</form>


The code in contact.php is:

<?php session_start();

if(!$_POST) exit;

    $address = 'email@emailaddress.com';
    $email_subject ="Add me to the mailing list";
    $email    = $_REQUEST['email'];
    $name     = $_REQUEST['name'];
    $subject  = "Please add me to the mailing list ";

        if(get_magic_quotes_gpc()) { $comment = stripslashes($comment); }


         $e_subject = 'You\'ve been contacted by ' . $name . '.';

         $msg  = "You have been contacted by $name with regards to $subject.\r\n\n";
         $msg .= "$message\r\n\n";
         $msg .= "You can contact $name via email, $email.\r\n\n";
         $msg .= "-------------------------------------------------------------------------------------------\r\n";

        if(@mail($address, $subject, $msg, "From: $email\r\nReturn-Path: $email\r\n"))
        {echo "<p class='ajax_success'>Thanks for Contact Us.</p>"; }
         else
         {echo "<p class='ajax_failure'>Sorry, Try again Later.</p>"; }
    header('Location:http://www.websiteaddress/homepage.html');
?>

【解决方案1】：

删除header 之前的所有输出在header 之后使用exit 并且还考虑在下面给出空格

                 v
header('Location: http://www.websiteaddress/homepage.html');
exit;

【解决方案2】：

使用正确的目录路径

if(isset($_POST['submit'])){
   $address = 'email@emailaddress.com';
    $email_subject ="Add me to the mailing list";
    $email    = $_REQUEST['email'];
    $name     = $_REQUEST['name'];
    $subject  = "Please add me to the mailing list ";

        if(get_magic_quotes_gpc()) { $comment = stripslashes($comment); }


         $e_subject = 'You\'ve been contacted by ' . $name . '.';

         $msg  = "You have been contacted by $name with regards to $subject.\r\n\n";
         $msg .= "$message\r\n\n";
         $msg .= "You can contact $name via email, $email.\r\n\n";
         $msg .= "-------------------------------------------------------------------------------------------\r\n";

        if(@mail($address, $subject, $msg, "From: $email\r\nReturn-Path: $email\r\n"))
        {echo "<p class='ajax_success'>Thanks for Contact Us.</p>"; }
         else
         {echo "<p class='ajax_failure'>Sorry, Try again Later.</p>"; }
            header('Location: homepage.html');
}

【解决方案3】：

在使用 header() 之前你不能输出任何东西

HTTP-Headers 应该在服务器的任何输出之前发送。如果你之前有输出，服务器会输出一个警告，比如'Headers already been sent'

<?php
 ob_start();

  echo "redirecting now ....";
  header('Location: http://www.websiteaddress/homepage.html');
  exit();

 ob_end_flush();
?>
