PHPMailer 发送重复的电子邮件

Question

问题： 我收到了三封重复的电子邮件，每个用户都使用他们的电子邮件地址注册。我的客人名单被重复的电子邮件淹没了，我不知道我的代码有什么问题。

Probable Cause: I have 3 signup forms, so I think somehow when I submit one signup form they all submit at the same time. The problem lies in either the Bootstrap 4.1.3 JS or the HTML.

PHP代码：

$email = $_REQUEST['email'] ;

// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require './PHPMailer-master/src/Exception.php';
require './PHPMailer-master/src/PHPMailer.php';
require './PHPMailer-master/src/SMTP.php';

// Popup Form Signup
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->Host = "mail.domain.com";
$mail->SMTPAuth = true;
$mail->Username = "user@domain.com"; 
$mail->Password = "password"; 
$mail->SMTPSecure = 'TLS';                           
$mail->Port = 587;
$mail->From = $email;
$mail->setFrom('$email', 'Guest');
$mail->addAddress('admin@domain.com', 'Admin');
$mail->IsHTML(true);
$mail->Subject = "New Member!";
$mail->Body = $email;
$mail->AltBody = $email;

$mail2 = new PHPMailer();
$mail2->IsSMTP();
$mail2->Host = "mail.domain.com"; 
$mail2->SMTPAuth = true; 
$mail2->Username = "user@domain.com"; 
$mail2->Password = "password"; 
$mail2->SMTPSecure = 'TLS';                      
$mail2->Port = 587;                             
$mail2->setFrom('support@domain.com', 'Support');
$mail2->AddAddress("$email");    
$mail2->AddReplyTo('support@domain.com');

    $mail2->Subject = "Thanks for signing up!";
    $message = '';
    $mail2->Body = $message;
    $mail2->AltBody = $message;


    if(!$mail2->Send())
    {
    echo "Message could not be sent. Please reload the page and try again. <p>";
    echo "Mailer Error: " . $mail2->ErrorInfo;
    exit;
    }

    if(!$mail->Send())
    {
    echo "Message was not received. Please reload the page and try again.<p>";
    echo "Mailer Error: " . $mail->ErrorInfo;
    exit;
    }

我还有其他可以打开不同 PHP 文件的表单，但它们不应该是这里的问题。我只是把它加在这里，以防万一有人能想出办法。

表格 1（同一着陆页）

<form class="signupForm1 input-group mt-1" method="post" action="topconfirm">
        <div class="input-group">
        <label for="email" class="sr-only">Enter your email address</label>
        <input style ="overflow:hidden;" id="email" type="email" name="email" required class="sentence form-control" aria-label="Large" placeholder="enter your email address">      
        <button style="font-size:17px;" name="topsubmit" type="submit" class="ctabutton semibolder submitButton sentence text-white btn btn-secondary px-lg-3 px-md-1 px-sm-1 btn-lg rounded-0">Get Started</button>
        </div>              
</form>

表格 2（相同的着陆页）

<form class="signupForm2 input-group mt-1" method="post" action="bottomconfirm">
                <div class="input-group">
                <label style="font-weight:normal!important;" for="email" class="sr-only">Enter your email address</label>
                <input style ="overflow:hidden;"  id="email" type="email" name="email" required class="sentence form-control" aria-label="Large" placeholder="enter your email address">         
                <input style="font-size:17px;" name="footersubmit" type="submit" class="ctabutton semibolder submitButton sentence text-white btn btn-secondary px-lg-3 px-md-1 px-sm-1 btn-lg rounded-0" value="Get Started"/>
                </div>              
        </form>

我不是 JavaScript 或 PHP 邮件专家请告诉我如何解决这个问题，我认为它可能是 Bootstrap JS 4.13。任何建议或帮助将不胜感激。谢谢！

我不知道你使用的是哪个版本的 PHPMailer，但你也在使用 PHP 的 mail() 方法，这很讽刺，因为你'我们还使用 PHPMailer。但是，尽管如此，这就是我在我的一个项目中的做法：

function sendAuthEmail($email, $token, $role) {
        try {
            $mail = new PHPMailer(true);
            $mail->SMTPDebug = 0; //SMTP Debug
            $mail->isSMTP();
            $mail->Host = "smtp.gmail.com";
            $mail->SMTPAuth = true;
            $mail->Username = 'example@example.com';
            $mail->Password = 'password';
            $mail->SMTPSecure = 'tls';
            $mail->Port = '587';
            /**
             * SMTPOptions work-around by @author : Synchro
             * This setting should removed on server and
             * mailing should be working on the server
             */
            $mail->SMTPOptions = array(
                'ssl' => array(
                    'verify_peer' => false,
                    'verify_peer_name' => false,
                    'allow_self_signed' => true
                )
            );

            // Recipients

            $mail->setFrom('no-reply@confirmation.com', 'Do Not Reply');
            $mail->addAddress($email, 'Yash Karanke'); // Add a recipient
            $mail->addReplyTo('no-reply@confirmation.com');

            // Content

            $mail->isHTML(true); // Set email format to HTML
            $mail->Subject = 'Authentication Email';
            $mail->Body = 'text to send';
            if ($mail->send()) {
                return true;
            }
            else {
                return false;
                exit();
            }
        }

        catch(Exception $e) {
            return $mail->ErrorInfo;
        }
    }

如果您正在寻找更简单的示例，请删除包装函数并仅使用您需要的代码。有关 Docs

的更多详细信息

在您的代码中，您使用的是 if(!$mail->send())，我不确定它是如何工作的，但您应该使用 if($mail->send())，这是文档中推荐的方式

此代码片段来自版本 6.0.3。

Answer 2

我认为深入研究您的 jQuery / JS 代码可能会找到答案，但我的猜测是您表单中的 button 元素会触发一些影响其他表单的事件。

您是否尝试将所有按钮更改为 <input type='submit'/>？

在您的服务器中启动会话并存储邮件发送信息

// Import PHPMailer classes into the global namespace
// These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require './PHPMailer-master/src/Exception.php';
require './PHPMailer-master/src/PHPMailer.php';
require './PHPMailer-master/src/SMTP.php';

// Popup Form Signup
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->Host = "mail.domain.com";
$mail->SMTPAuth = true;
$mail->Username = "user@domain.com"; 
$mail->Password = "password"; 
$mail->SMTPSecure = 'TLS';                           
$mail->Port = 587;
$mail->From = $email;
$mail->setFrom('$email', 'Guest');
$mail->addAddress('admin@domain.com', 'Admin');
$mail->IsHTML(true);
$mail->Subject = "New Member!";
$mail->Body = $email;
$mail->AltBody = $email;

$mail2 = new PHPMailer();
$mail2->IsSMTP();
$mail2->Host = "mail.domain.com"; 
$mail2->SMTPAuth = true; 
$mail2->Username = "user@domain.com"; 
$mail2->Password = "password"; 
$mail2->SMTPSecure = 'TLS';                      
$mail2->Port = 587;                             
$mail2->setFrom('support@domain.com', 'Support');
$mail2->AddAddress("$email");    
$mail2->AddReplyTo('support@domain.com');

    $mail2->Subject = "Thanks for signing up!";
    $message = '';
    $mail2->Body = $message;
    $mail2->AltBody = $message;


if(!$_SESSION['is_mail_1_send']){//check mail sended once
    if(!$mail2->Send())
    {
    echo "Message could not be sent. Please reload the page and try again. <p>";
    echo "Mailer Error: " . $mail2->ErrorInfo;
   $_SESSION['is_mail_1_send']=false;
 exit;
    }else{
            $_SESSION['is_mail_1_send']=true;   
    }
}
if(!$_SESSION['is_mail_2_send']){//check mail sended once
    if(!$mail->Send())
    {
    echo "Message was not received. Please reload the page and try again.<p>";
    echo "Mailer Error: " . $mail->ErrorInfo;
$_SESSION['is_mail_2_send']=false;
    exit;
    }else{
        $_SESSION['is_mail_2_send']=true;
    }
}

?>

Answer 4

Where you are handling form submit event? Create a separate function for sending mail. call that function when user click on specific form submit button. like below

// Your separate Mail sending function
sendMail(arg1, arg2, arg3){
   // PHP Mailer Configurations
}

// Calling your first form
if(isset($_POST['topsubmit']){
  sendMail(arg1, arg2, arg3);
}

// Calling your second form
if(isset($_POST['footersubmit']){
  sendMail(arg1, arg2, arg3);
}

Answer 5

尝试为每个按钮创建一个单独的 submit() 函数（使用 onclick 处理程序）并从中删除 value='submit'，如下所示：

    <!--signupform1-->
    <form class="signupForm1 input-group mt-1" method="post" action="topconfirm">
        <div class="input-group">
            <label for="email" class="sr-only">Enter your email address</label>
            <input style ="overflow:hidden;" id="email" type="email" name="email" required class="sentence form-control" aria-label="Large" placeholder="enter your email address">      
            <button style="font-size:17px;" name="topsubmit" type="button" class="ctabutton semibolder submitButton sentence text-white btn btn-secondary px-lg-3 px-md-1 px-sm-1 btn-lg rounded-0" onclick="submit1();">Get Started</button>
        </div>              
    </form>

    <!--signupform2-->
    <form class="signupForm2 input-group mt-1" method="post" action="bottomconfirm">
        <div class="input-group">
            <label style="font-weight:normal!important;" for="email" class="sr-only">Enter your email address</label>
            <input style ="overflow:hidden;"  id="email" type="email" name="email" required class="sentence form-control" aria-label="Large" placeholder="enter your email address">         
            <input style="font-size:17px;" name="footersubmit" type="button" class="ctabutton semibolder submitButton sentence text-white btn btn-secondary px-lg-3 px-md-1 px-sm-1 btn-lg rounded-0" onclick="submit2();" value="Get Started"/>
        </div>              
    </form>

然后在你的js中：

<script>
    function submit1() {
        $(".signupForm1").submit();
    }
    function submit2() {
        $(".signupForm2").submit();
    }
</script>

Answer 6

首先：Bootstrap 不是这里的罪魁祸首，JS 也不是。如果 PHP（或 php 邮件程序）也很干净，那么您可能需要查看邮件服务器设置（与您的主机核实）。

但是，也许表单被提交了两次？让我们检查一下：

打开googlechrome调试器(F12)
点击 "Network"，勾选 "Preserve log"
单击 "Clear"（左侧第二个图标）
运行您的楷书（即填写表格并提交）
"Network" 选项卡将显示您的 PHP 页面的任何重复调用

如果还是失败，试试这个：

下载https://github.com/PHPMailer/PHPMailer

创建一个完全空白的文件，直接将您的 PHP 电子邮件行放入其中。删除表单、输入、javascript、isset 和其余部分。运行通过简单地调用这个文件，它看起来像：

    require_once("PHPMailerAutoload.php"); // <---- only this will be required (put your path properly)

    $mail2 = new PHPMailer();
    $mail2->IsSMTP();
    $mail2->Host = "mail.domain.com"; 
    $mail2->SMTPAuth = true; 
    $mail2->Username = "user@domain.com"; 
    $mail2->Password = "password"; 
    $mail2->SMTPSecure = 'TLS';                      
    $mail2->Port = 587;                             
    $mail2->setFrom('support@domain.com', 'Support');
    $mail2->AddAddress("$email");    
    $mail2->AddReplyTo('support@domain.com');

    $mail2->Subject = "Thanks for signing up!";
    $message = '';
    $mail2->Body = $message;
    $mail2->AltBody = $message;


    if(!$mail2->Send())
    {
    echo "Message could not be sent. Please reload the page and try again. 
    <p>";
    echo "Mailer Error: " . $mail2->ErrorInfo;
    exit;
    }

祝你好运

Answer 7

我的理解正确吗？ o_O

当然，使用 php 代码，您将发送多封电子邮件。

只需像这样更改您的 php 代码，以便您解析 mail1 和 mail2 有条件地分隔：

if (!empty($_POST['topsubmit']))
{
    $mail2 = new PHPMailer();
    ...
    if(!$mail2->Send())
    ...
}

if (!empty($_POST['footersubmit']))
{
    $mail2 = new PHPMailer();
    ...
    if(!$mail2->Send())
    ...
}

因此，不会在同一页面加载时发送所有电子邮件。

Answer 8

这是我问题的完整答案，感谢@SearchingSolutions 向我展示了解决此问题的正确方法。

我为解决这个问题所做的是创建 2 个不同的按钮，每个按钮都有单独的 onclick-handlers。每个按钮都有不同的 ID，我在两者上都添加了 TYPE="Submit"。我给每个表单一个不同的名称，并添加了一个小的 JS 脚本来在调用特定的 onclick 处理程序时提交特定的表单。

到目前为止，每封电子邮件都按预期收到，一切都再次运行顺利。

谢谢大家的精彩解答！

HTML:

<form class="signupForm1 input-group mt-1" method="post" action="topconfirm">
        <div class="input-group">
        <label for="email2" class="sr-only">Enter your email address</label>
        <input style ="overflow:hidden;" id="email2" type="email" name="email2" required class="sentence form-control" aria-label="Large" placeholder="enter your email address">        
        <button style="font-size:17px;" name="topsubmit" type="submit" class="ctabutton semibolder sentence text-white btn btn-secondary px-lg-3 px-md-1 px-sm-1 btn-lg rounded-0" onclick="submit1();">Get Started"</button>
        </div>              
</form>


<form class="signupForm2 input-group mt-1" method="post" action="footerconfirm">
        <div class="input-group">
        <label style="font-weight:normal!important;" for="email3" class="sr-only">Enter your email address</label>
        <input style ="overflow:hidden;"  id="email3" type="email" name="email3" required class="sentence form-control" aria-label="Large" placeholder="enter your email address">       
        <button style="font-size:17px;" name="footersubmit" type="submit" class="ctabutton semibolder sentence text-white btn btn-secondary px-lg-3 px-md-1 px-sm-1 btn-lg rounded-0" onclick="submit2();">Get Started"</button>
        </div>              
</form>

JS 脚本：

<script>
function submit1() {
    $(".signupForm1").submit();
}
function submit2() {
    $(".signupForm2").submit();
