【中文标题】PHP 联系表，一直工作到迁移。警告：mail() [function.mail]：mail() 函数的参数错误，邮件未发送【英文标题】：Php contact form, worked until migration. Warning: mail() [function.mail]: Bad parameters to mail() function, mail not sent 【发布时间】：2014-01-18 19:51:09 【问题描述】：

这就是问题所在，我已经在此问题上构建了自定义联系表单已有一段时间了。它的工作方式与我的开发（php 5.3.10）服务器上的假设方式相同。当我将表单上传到 Godaddy 主机并进行测试时，会出现问题。我得到以下信息：

Warning: mail() [function.mail]: Bad parameters to mail() function, mail not sent. in index.php on line 146

这行说明：

if (mail($mailto, $subject, "", $headers))

这里是完整的脚本：

    <!DOCTYPE html> 
<html>
<head>
<style>
.error color: #FF0000;
</style>
</head>
<body> 

<?php
// define variables and set to empty values
$nameErr = $emailErr = $commentErr = $companyErr = $phoneErr = "";
$name = $email = $company = $comment = $phone = "";

if ($_SERVER["REQUEST_METHOD"] == "POST")

   if (empty($_POST["name"]))
     $nameErr = "Name is required";
   else
     
     $name = test_input($_POST["name"]);
     // check if name only contains letters and whitespace
     if (!preg_match("/^[a-zA-Z ]*$/",$name))
       
       $nameErr = "Only letters and white space allowed"; 
       
     

    if (empty($_POST["company"]))
         $companyErr = "company is required";
       else
         $company = test_input($_POST["company"]);

   if (empty($_POST["email"]))
     $emailErr = "Email is required";
   else
     
     $email = test_input($_POST["email"]);
     // check if e-mail address syntax is valid
     if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email))
       
       $emailErr = "Invalid email format"; 
       
     

   if (empty($_POST["phone"]))
     $phoneErr = "phone is required";
   else
     $phone = test_input($_POST["phone"]);

 if (empty($_POST["comment"]))
   $commentErr = "comment is required";
 else
   $comment = test_input($_POST["comment"]);



function test_input($data)

     $data = trim($data);
     $data = stripslashes($data);
     $data = htmlspecialchars($data);
     return $data;

我猜这是一个老生常谈的问题，因为它在我的开发服务器上完美运行。客户端没有让我访问任何 Godaddy 信息，只有 FTP 上的单个目录访问权限。我多么喜欢偏执的客户！！！

对此的任何帮助将不胜感激！提前感谢洛茨！！！

【问题讨论】：

您的开发服务器上是否启用了错误和警告？ 如果输入非空消息会怎样？ 您的错误是您迁移到的当前主机不支持您传递的标头，或者至少不支持您传递的变量中的某些数据。最常见的是 \r\n 试图在标题中使用。 另外，如果将$attch1 更改为something@your-domain-on-godaddy.com 并将Reply-To 设置为$_POST['email'] 会发生什么？ 我在开发服务器上启用了错误和警告。仍然在那里工作。将尝试从标题中删除 \r\n。 【参考方案1】：

两种可能性。

首先，简单的一个：您的某些 EOL 看起来有问题。主标题应该是：

$headers = "From: $attch1" . $eol;
$headers .= "MIME-Version: 1.0" . $eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol;
$headers .= "Content-Transfer-Encoding: 7bit" . $eol . $eol;
$headers .= "This is a MIME encoded message." . $eol . $eol;

主标题和正文之间应该有两个 EOL。 Content-Transfer-Encoding 应该是主标题的一部分，This is a MIME encoded message 是正文的开头。

更复杂的一个：可能GoDaddy运行的PHP版本不允许你将消息内容放在$additional_headers参数中。消息正文应在第三个参数中发送到mail()。试试这个：

<?php
// main header (multipart mandatory)
$headers = "From: $attch1" . $eol;
$headers .= "MIME-Version: 1.0" . $eol;
$headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol
$headers .= "Content-Transfer-Encoding: 7bit";

// message
$body = "This is a MIME encoded message." . $eol . $eol;
$body .= "--" . $separator . $eol;
$body .= "Content-Type: text/plain; charset=\"iso-8859-1\"" . $eol;
$body .= "Content-Transfer-Encoding: 8bit" . $eol . $eol;
$body .= $message . $eol . $eol;

// attachment
$body .= "--" . $separator . $eol;
$body .= "Content-Type: application/octet-stream; name=\"" . $file . "\"" . $eol;
$body .= "Content-Transfer-Encoding: base64" . $eol;
$body .= "Content-Disposition: attachment" . $eol . $eol;
$body .= $content . $eol . $eol;
$body .= "--" . $separator . "--";

//SEND Mail
if (mail($mailto, $subject, $body, $headers)) 
    echo "Thank you for submitting our form successfully"; // or use booleans here
 else 
    echo "Submission ERROR! Please try again";

【讨论】：

G'rrr 尝试加载一个空白页面。仍然没有显示错误。当我启用它们时，Php 没有向我显示任何问题是怎么回事？感谢您尝试帮助我。 这是一个语法错误。标题中的Content-Type 行缺少; 谢谢迈克！并感谢 Barmar 给了我更好的格式：D。这似乎在开发人员服务器上工作。迁移到 godaddy 的过程并不顺利。同样的问题 @MarvilJoy 在最后一个分隔符之前添加另一个分隔符、附件标题和内容。如果您尝试过但没有成功，请使用您的代码发布问题。
