我试着创建了一个简单的邮件表单。表单本身在我的index.html页面上,但它提交到一个单独的“感谢您的提交”页面thanks . PHP,其中嵌入了上述PHP代码。 代码完美地提交,但从未发送电子邮件。我该如何解决这个问题?

如果您正在使用SMTP配置来发送电子邮件,请尝试使用PHPMailer。您可以从https://github.com/PHPMailer/PHPMailer下载该库。

我用这种方式创建了我的电子邮件:

function send_mail($email, $recipient_name, $message='')
{
    require("phpmailer/class.phpmailer.php");

    $mail = new PHPMailer();

    $mail->CharSet = "utf-8";
    $mail->IsSMTP();                                      // Set mailer to use SMTP
    $mail->Host = "mail.example.com";  // Specify main and backup server
    $mail->SMTPAuth = true;     // Turn on SMTP authentication
    $mail->Username = "myusername";  // SMTP username
    $mail->Password = "p@ssw0rd"; // SMTP password

    $mail->From = "me@walalang.com";
    $mail->FromName = "System-Ad";
    $mail->AddAddress($email, $recipient_name);

    $mail->WordWrap = 50;                                 // Set word wrap to 50 characters
    $mail->IsHTML(true);                                  // Set email format to HTML (true) or plain text (false)

    $mail->Subject = "This is a Sampleenter code here Email";
    $mail->Body    = $message;
    $mail->AltBody = "This is the body in plain text for non-HTML mail clients";
    $mail->AddEmbeddedImage('images/logo.png', 'logo', 'logo.png');
    $mail->addAttachment('files/file.xlsx');

    if(!$mail->Send())
    {
       echo "Message could not be sent. <p>";
       echo "Mailer Error: " . $mail->ErrorInfo;
       exit;
    }

    echo "Message has been sent";
}

你可以通过以下方法查看错误:

error_reporting(E_ALL);

我的示例代码是:

<?php
    use PHPMailer\PHPMailer\PHPMailer;
    require 'PHPMailer.php';
    require 'SMTP.php';
    require 'Exception.php';

    $name = $_POST['name'];
    $mailid = $_POST['mail'];
    $mail = new PHPMailer;
    $mail->IsSMTP();
    $mail->SMTPDebug = 0;                   // Set mailer to use SMTP
    $mail->Host = 'smtp.gmail.com';         // Specify main and backup server
    $mail->Port = 587;                      // Set the SMTP port
    $mail->SMTPAuth = true;                 // Enable SMTP authentication
    $mail->Username = 'someone@gmail.com';  // SMTP username
    $mail->Password = 'password';           // SMTP password
    $mail->SMTPSecure = 'tls';              // Enable encryption, 'ssl' also accepted

    $mail->From = 'someone@gmail.com';
    $mail->FromName = 'name';
    $mail->AddAddress($mailid, $name);       // Name is optional
    $mail->IsHTML(true);                     // Set email format to HTML
    $mail->Subject = 'Here is the subject';
    $mail->Body    = 'Here is your message' ;
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
    if (!$mail->Send()) {
       echo 'Message could not be sent.';
       echo 'Mailer Error: ' . $mail->ErrorInfo;
       exit;
    }
    echo 'Message has been sent';
?>

只需在发送邮件之前添加一些标题:

<?php 
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$from = 'From: yoursite.com'; 
$to = 'contact@yoursite.com'; 
$subject = 'Customer Inquiry';
$body = "From: $name\n E-Mail: $email\n Message:\n $message";

$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html\r\n";
$headers .= 'From: from@example.com' . "\r\n" .
'Reply-To: reply@example.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);

还有一件事。mail()函数在本地主机中不起作用。将代码上传到服务器并尝试。

如果您正在使用SMTP配置来发送电子邮件,请尝试使用PHPMailer。您可以从https://github.com/PHPMailer/PHPMailer下载该库。

我用这种方式创建了我的电子邮件:

function send_mail($email, $recipient_name, $message='')

    $mail->CharSet = "utf-8";
    $mail->IsSMTP();                                      // Set mailer to use SMTP
    $mail->Host = "mail.example.com";  // Specify main and backup server
    $mail->SMTPAuth = true;     // Turn on SMTP authentication
    $mail->Username = "myusername";  // SMTP username
    $mail->Password = "p@ssw0rd"; // SMTP password

    $mail->From = "me@walalang.com";
    $mail->FromName = "System-Ad";
    $mail->AddAddress($email, $recipient_name);

    $mail->WordWrap = 50;                                 // Set word wrap to 50 characters
    $mail->IsHTML(true);                                  // Set email format to HTML (true) or plain text (false)

    $mail->Subject = "This is a Sampleenter code here Email";
    $mail->Body    = $message;
    $mail->AltBody = "This is the body in plain text for non-HTML mail clients";
    $mail->AddEmbeddedImage('images/logo.png', 'logo', 'logo.png');
    $mail->addAttachment('files/file.xlsx');

    if(!$mail->Send())
    {
       echo "Message could not be sent. <p>";
       echo "Mailer Error: " . $mail->ErrorInfo;
       exit;
    }

    echo "Message has been sent";
}

总是尝试在邮件函数中发送标题。 如果您通过localhost发送邮件,则执行SMTP设置以发送邮件。 如果您通过服务器发送邮件,请检查您的服务器上是否启用了电子邮件发送功能。

对于那些不想使用外部邮件并且希望在专用的Linux服务器上使用mail()的人。

PHP如何发送邮件,详见PHP .ini中[邮件函数]一节。

参数sendmail-path描述如何调用sendmail。默认值是sendmail -t -i,因此如果您在Linux控制台中得到一个正常工作的sendmail -t -i < message.txt,那么您就完成了。您还可以将mail.log添加到调试中,并确保真正调用了mail()。

不同的mta可以实现sendmail。它们只是在这个名称上创建一个符号链接到它们的二进制文件。例如,在Debian中,默认是后缀。配置MTA以发送邮件并从控制台使用sendmail -v -t -i < message.txt进行测试。文件message.txt应该包含消息的所有头和正文,信封的目的地址将从To:头中获取。例子:

From: myapp@example.com
To: mymail@example.com
Subject: Test mail via sendmail.

Text body.

我更喜欢使用smtp作为MTA,因为它简单,不需要运行开放端口的守护进程。smtp仅适用于从本地主机发送邮件。它还可以通过公共邮件服务通过您的帐户发送经过认证的电子邮件。安装ssmtp,编辑配置文件/etc/ssmtp/ssmtp.conf。配置/etc/ssmtp/revaliases文件也能够接收本地系统邮件到Unix帐户(例如,从cron作业到root的警报)。

以下是我在Yandex邮箱上的账户配置:

root=mymail@example.com
mailhub=smtp.yandex.ru:465
FromLineOverride=YES
UseTLS=YES
AuthUser=abcde@yandex.ru
AuthPass=password
