问题：我收到每位使用其电子邮件地址注册的用户的三封重复电子邮件。我的来宾列表被重复的电子邮件所淹没，我不知道我的代码有什么问题。
可能的原因：我有3个注册表单，所以我认为以某种方式提交一份注册表单时，它们都会同时提交。问题出在Bootstrap 4.1.3 JS或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;
}
我也有其他打开不同PHP文件的窗体，但是这里不应该成为问题。我只是在这里添加了它，以防万一有人可以解决。
FORM 1（相同的着陆页）
<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>
FORM 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，请向我展示如何解决此问题，我认为这可能是Bootstrap JS 4.13。任何建议或帮助将不胜感激。谢谢！

尝试为每个按钮创建一个单独的commit（）函数（带有onclick句柄），然后从其中删除value='submit'，就像这样：
<!--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>
然后在您的js中：
<script>
function submit1() {
$(".signupForm1").submit();
}
function submit2() {
$(".signupForm2").submit();
}
</script>

首先，引导不是这里的罪魁祸首，JS也不是。而且，如果PHP（或php mailer）也很干净，那么您可能想看看邮件服务器的设置（请与您的主机联系）。
但是，也许表单被提交了两次？让我们检查一下：
如果仍然失败，请尝试以下操作：
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和其他内容。只需调用它即可运行该文件，因此它看起来像：
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;
}
好运

我不知道您使用的是哪个版本的PHPMailer，但是您还使用了PHP的mail()方法，这很具有讽刺意味，因为您还使用了PHPMailer。但是，尽管如此，这是我在一个项目中做到的：
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 $mail->ErrorInfo;
}
}
如果您正在寻找一个更简单的示例，请删除包装的函数并仅使用所需的代码。有关Docs
的更多详细信息在您的代码中，您不确定使用if(!$mail->send())，它是如何工作的，但是您应该使用if($mail->send())，这是文档中推荐的方式
此代码段来自6.0.3版。

我认为深入研究jQuery / JS代码可能会带来答案，但是我的猜测是表单中的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都更改为<input type='submit'/>？

在服务器中启动会话并存储邮件发送的信息
Rest答案 5 :(得分：0)
您在哪里处理表单提交事件？创建一个单独的功能 发送邮件。当用户单击特定表单时调用该函数 提交按钮。像下面一样
// 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);
}

我理解正确吗？ o_O
当然，有了该php代码，您就可以发送多封电子邮件。
只需像这样更改您的php代码，即可解析有条件地分隔的mail1和mail2：
if (!empty($_POST['topsubmit']))
{
$mail2 = new PHPMailer();
...
if(!$mail2->Send())
...
}
if (!empty($_POST['footersubmit']))
{
$mail2 = new PHPMailer();
...
if(!$mail2->Send())
...
}
因此，所有电子邮件都不会在同一页面加载中发送。

这是我问题的完整答案，这要感谢@SearchingSolutions向我展示了解决此问题的正确方法。
我要解决此问题的方法是创建2个不同的按钮，并为每个按钮使用单独的onclick句柄。每个按钮都有不同的ID，我在两个按钮上都添加了 TYPE =“ Submit” 。我给每种表单起了不同的名称，并添加了一个小的JS脚本，以便在调用特定的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发送，并且一切都再次正常运行。
谢谢大家的好评！
