PHPmailer重复电子邮件问题 - 条件语句与$ mail-> Send() [英] PHPmailer duplicate email issue - conditional statement with $mail->Send()
问题描述
我遇到了一个奇怪的问题,PHPmailer(5.1版),我正在努力解决。我在这里看到很多好的反馈,所以我以为我会试一试。我发现当我尝试使用基于 $ mail-> send()
的条件语句创建一个自定义的确认消息时,我收到重复的电子邮件。我可以用phpmailer下载的通用testemail.php脚本来复制它。以下是代码:
I came across a bizarre issue with PHPmailer (version 5.1) that I'm trying to work around. I've seen quite a bit of good feedback on here, so I thought I would give it a try. I've found that when I attempt to create a customized confirmation message with a conditional statement based on $mail->send()
, I receive duplicate emails. I can duplicate it with the generic testemail.php script that comes with the phpmailer download. Here's the code:
require'../class.phpmailer.php';
try {
$ mail = new PHPMailer(true); //新实例,启用异常
$ mail-> SMTPDebug = 1;
$ mail-> IsSMTP(); //告诉班级使用SMTP
$ mail-> SMTPAuth = true; //启用SMTP身份验证
$ mail-> Port = 25; //设置SMTP服务器端口
$ mail-> Host =mail.domain.com; // SMTP服务器
$ mail-> Username =username; // SMTP服务器用户名
$ mail-> Password =password; // SMTP服务器密码
require '../class.phpmailer.php';
try {
$mail = new PHPMailer(true); //New instance, with exceptions enabled
$mail->SMTPDebug = 1;
$mail->IsSMTP(); // tell the class to use SMTP
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Port = 25; // set the SMTP server port
$mail->Host = "mail.domain.com"; // SMTP server
$mail->Username = "username"; // SMTP server username
$mail->Password = "password"; // SMTP server password
$mail->IsSendmail();
$mail->From = "example_from@domain.com";
$mail->FromName = "First Last";
$to = "example@domain.com";
$mail->AddAddress($to);
$mail->Subject = "PHP Mailer test";
$message = "This is a test. \n";
$mail->Body = $message;
$mail->Send();
if ($mail->Send()) {
echo 'Message has been sent.';
} else {
echo "Mailer Error: " . $mail->ErrorInfo;
}
} catch(phpmailerException $ e){
echo $ e-> errorMessage();
}
} catch (phpmailerException $e) {
echo $e->errorMessage();
}
上述代码回应已发送消息确认,但随后发送两封电子邮件。如果我注释掉 $ mail-> send()
行,我仍然收到消息已发送确认,只收到一条消息。如果我删除条件语句,并留下 $ mail-> send()
行注释掉,不会发送任何电子邮件。
The above code echoes the "Message has been sent" confirmation, but then sends two emails. If I comment out the $mail->send()
line, I still receive the "message has been sent" confirmation and only get one message. If I remove the conditional statement and leave the $mail->send()
line commented out, no email is sent.
为什么添加条件语句会导致发送电子邮件而不调用 $ mail-> send()
方法?添加自定义确认消息的正确方法是什么?
Why does adding a conditional statement cause an email to be sent without calling the $mail->send()
method? What is the proper way of adding a customized confirmation message?
推荐答案
当您将 $ mail-> Send()
您有条件的,您实际上正在再次呼叫,发送另一条消息,并检查是否发送了第二条消息。
When you put $mail->Send()
in your conditional, you're actually calling it again, sending another message, and checking if that second message was sent.
如果您只是保持
if ($mail->Send()) {
echo 'Message has been sent.';
} else {
echo "Mailer Error: " . $mail->ErrorInfo;
}
并摆脱原始的无条件发送电话,你应该没事。
and get rid of the original, unconditional Send call, you should be fine.
或者,如果您更清楚,或者您需要在其他地方进行某些处理,这取决于邮件是否成功发送,您可以基本上等效: p>
Alternatively, if it's clearer for you or if you need to do some processing elsewhere that depends on whether the message was successfully sent, you could do the essentially equivalent:
$status = $mail->Send();
if ($status) {
echo 'Message has been sent.';
} else {
echo "Mailer Error: " . $mail->ErrorInfo;
}
