我多年来一直在使用php表单，但知道的很少......这很危险......（我花了两天的时间让Google重新验证验证工作几个月，但表单工作正常）。< / p>
我现在已经注意到，当我在Outlook 2016的from字段中收到回复时，发件人电子邮件出现两次，标题部分没有任何空格。
因此，当我回复时，我在电子邮件地址中有两次电子邮件。
我问托管公司，但他们说他们无法帮助。
用php中的标题如下： 例1：
$headers = "From: $email";
$headers .= " $email";
我在表单字段中收到了双重电子邮件。
-----Original Message-----
From: sendersemail@gmail.com sendersemail@gmail.com [mailto:sendersemail@gmail.com myemail@gmail.com]
Sent: 08 November 2015 12:04
To: myemail@gmail.com
Subject: Contact Form
name: Mark
email: sendersemail@gmail.com
phone_number: 12345
message: hi
但是，如果我按照另一个帖子更改标题
例2：
$headers .= "Reply-To: $email";
$headers = "From: $email";
表单字段然后更改为我的username@whm4.bargainhosts.co.uk但不是两次
-----Original Message-----
From: username@whm4.bargainhosts.co.uk [mailto:username@whm4.bargainhosts.co.uk]
Sent: 08 November 2015 12:00
To: myemail@gmail.com
Subject: Contact Form
name: Mark
email: sendersemail@gmail.com
phone_number: 12345
message: hi again
用于工作的表格没有任何问题，也没有改变任何内容。
服务器php更新是否导致我的代码现在无法正常工作？
我要做的就是能够回复发件人而无需删除第二封电子邮件。并且发件人的电子邮件地址位于发件人字段中，而不是username@whm4.bargainhosts.co.uk
欢迎任何帮助。
谢谢Mark
网站联系表单用于发送到我现在提供的php代码。
<?php
$email = $_POST['email'];
$after = "http://www.website.co.uk/thankyou.htm";
$oops = "http://www.website.co.uk/error.htm";
if (!isset($_POST['submit']) || $_SERVER['REQUEST_METHOD'] != "POST") {
exit("<p>You did not press the submit button; this page should not be accessed directly.</p>");
}if(isset($_POST['g-recaptcha-response'])){
$captcha=$_POST['g-recaptcha-response'];
}
if(!$captcha){
echo "<meta HTTP-EQUIV=\"REFRESH\" content=\"0; url=$oops\">";
exit;
}
$response=file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=##########secretcode#########&response=".$captcha."&remoteip=".$_SERVER['REMOTE_ADDR']);
if($response.success==false)
{
echo "<meta HTTP-EQUIV=\"REFRESH\" content=\"0; url=$oops\">";
}else
{
echo "<meta HTTP-EQUIV=\"REFRESH\" content=\"0; url=$after\">";
}
if( isset($_POST['submit'])) {
$recipient = "myemail@gmail.com";
$title = "Contact Form";
$message .= "name: {$_POST['name']} \n";
$message .= "email: {$_POST['email']} \n";
$message .= "phone_number: {$_POST['phone_number']} \n";
$message .= "their-message: {$_POST['their-message']} \n";
$headers .= "Reply-To: $email";
$headers .= "From: $email";
mail($recipient,$title,$message,$headers);
}
?>
以下是网站上使用的代码
<div id="contact_form">

答案 0 :(得分：1)
以下内容可能会写在两行，但实际上会将电子邮件地址连接到以前的电子邮件地址。
$headers = "From: $email";
$headers .= " $email";/* try commenting out this line */
如
所示From: myemail@gmail.com myemail@gmail.com [mailto:myemail@gmail.com myemail@gmail.com]
并在下面覆盖第二行的头变量，因为你没有连接字符串。
$headers .= "Reply-To: $email";
$headers = "From: $email";
尝试将其更改为：
$headers .= "Reply-To: $email";
$headers .= "From: $email";
基于你原来的，因为它在苏格兰下雨，我感到无聊，我写了这篇文章，我希望它会有所帮助。我认为其中一个问题是标题中使用的行结尾，如下面的评论中所述，在访问验证码检查的返回值时，语法似乎有点奇怪。
在包含表单的页面上，我使用了以下所有测试：
head
----
<script type='text/javascript'>
var key='<?php echo GOOGLE_RECAPTCHA_KEY; ?>';
/* this is the public key */
function verifyCaptcha(){
grecaptcha.render( 'grc', {
'sitekey' : key,
'theme' : 'light',
'size' : 'compact'
});
}
</script>
<script src='https://www.google.com/recaptcha/api.js?onload=verifyCaptcha&render=explicit' async defer></script>
body
----
<form name='mailtest' method='post' action='/test/target.php'>
<h1>Google reCaptcha form mail test</h1>
<input type='text' name='name' placeholder='Please enter your name' required />
<input type='text' name='phone_number' placeholder='Please enter your phone' required />
<input type='text' name='their-message' placeholder='Please enter your message' required />
<input type='email' name='email' placeholder='Please enter your email address' required />
<!-- empty placeholder for re-captcha -->
<div id='grc'></div>
<!-- A new form element will be created by the recaptcha if successful -->
<!--
g-recaptcha-response
-->
<input type="submit" value="Send email" />
</form>
form action script

<?php
$after = "http://www.website.co.uk/thankyou.htm";
$oops = "http://www.website.co.uk/error.htm";

/* Config: edit these to suit */
$recipient='myemail@gmail.com';
$subject='Contact Form Enquiry';
$google_secret='abc-def-123-456xxxxxxxxx';
/* Container in which to build message */
$message=array();
$headers=array();
/* Fields of relevance to the email */
$fields=array( 'email', 'submit', 'name', 'phone_number', 'their-message' );
foreach( $fields as $field ){
/* Assign as a variable variable */
$$field=( isset( $_POST[ $field ] ) && !empty( $_POST[ $field ] ) ) ? trim( filter_input( INPUT_POST, $field, FILTER_SANITIZE_STRING ) ) : false;
/* Add to message */
if( $$field ) $message[]="{$field}: {$$field}";

$response=file_get_contents( "https://www.google.com/recaptcha/api/siteverify?secret=".$google_secret."&response=".trim( $captcha )."&remoteip=".$_SERVER['REMOTE_ADDR'] );

exit("mail( \"$recipient\", \"$subject\", \"".implode( PHP_EOL, $message )."\", \"".implode( "\r\n", $headers )."\" )");

?>
成功验证和表单提交后，调试的输出为：
邮件（＆＃34; myemail@gmail.com"，＆＃34;联系表格查询＆＃34;， ＆＃34;电子邮件：joe.bloggs@example.com名称：joe bloggs phone_number：0141 353 3789他们的消息：您好，我需要您的帮助......这么久，谢谢 所有的鱼＆＃34;，＆＃34;来自：joe.bloggs@example.com回复： joe.bloggs@example.com" ）
示例输出未显示的是{-1}}的行尾。顺便提一下，我假设网址\r\n只是用作例{〜www.website.co.uk？如果没有，表格的行动就会出现拼写错误。
