Question

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">
       <form name="form" id="ff" method="post" action="http://www.webwsite.co.uk/c/form2015.php">
         <legend>Please help us by completing all fields</legend>
         <br>
         <label> <span>Name*:</span><br>
           <input type="text" placeholder="Please enter your name" name="name" id="name" required>
         </label>
         <label> <span>Email*:</span><br>
           <input type="email" placeholder="youremail@gmail.com" name="email" id="email" required>
         </label>
         <label> <span>Phone:</span><br>
           <input type="phone_number" placeholder="Please enter your phone" name="phone_number" id="phone_number">
         </label>
         <label> <span>Message*:</span><br>
           <textarea name="their-message" rows="5" required id="their-message" placeholder="Please enter your message"></textarea>
         </label>
         <div class="g-recaptcha" data-sitekey="################################################"></div>
         <br />
         <input name="Reset" id="reset" type="reset" class="reset" value="Reset" />
         <input name="submit" type="submit" class="submit"  value="Send" />
       </form>
     </div>

Answer 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";

    if( $_SERVER['REQUEST_METHOD']=='POST' ){


        /* 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}";
        }

        /* Add elements to the headers array */
        $headers[]="From: {$email}";
        $headers[]="Reply-To: {$email}";

        /*
            These are pertinent to Outlook so could be set too
            --------------------------------------------------

            $headers[]="Importance: Normal";
            $headers[]="Sensitivity: Private";

            $headers[]="Keywords: x,y,z";

            $headers[]="Cc: user@example.com";
            $headers[]="Bcc: user@example.com";

        */


        /* Get submitted captcha image data */
        $captcha=isset( $_POST['g-recaptcha-response'] ) && !empty( $_POST['g-recaptcha-response'] ) ? $_POST['g-recaptcha-response'] : false;
        if( !!$captcha===false ) header( 'location: '.$oops.'?captcha=empty' );


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

        /* The syntax you had seemed incorrect as it used a dot notation */
        if( $response->success ){
            /* To debug output and expected mail send parameters */
            exit("mail( \"$recipient\", \"$subject\", \"".implode( PHP_EOL, $message )."\", \"".implode( "\r\n", $headers )."\" )");

            /* Send the mail*/
            $res=@mail( $recipient, $subject, implode( "\n", $message ), implode( "\r\n", $headers ) );

            /* Redirect based upon mail sending success / failure */
            if( $res ) header( 'location: '.$after.'?mailsent=true' );
            else header( 'location: '.$oops.'?mailsent=false' );

        } else {
            /* Get the reason straight from the horses mouth */
            $reason=implode('_',$response->{'error-codes'});

            /* Redirect because capture failed */
            header( 'location: '.$oops.'?captcha=failed&reason='.$reason );
        }


    } else {
        /* Redirect - incorrect method */
        header( 'location: '.$oops.'?method=bad' ); 
    }
?>

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。

当我在from字段中收到表单回复两次列出电子邮件时？
