php - 如何修复 sendmail.php 不起作用？

Question

我有网站，我不是专业人士，但我已经完成了，除了 sendmail 问题。当我单击“立即发送”按钮时，屏幕上会显示“感谢您的消息”消息，但我没有收到任何电子邮件。

• 我检查了垃圾邮件箱它也没有

• 我检查了 phpinfo SMTP 端口打开和 25

• 我检查了 phpinfo senmail_path/usr/sbin/sendmail -t -i

• 我调用托管公司并发送了电子邮件，他们说一切正常服务器端检查您的 sendmail 脚本。

这里是sendmail.php文件；

<?php
$name       = @trim(stripslashes($_POST['name']));
$from       = @trim(stripslashes($_POST['email'])); 
$subject    = @trim(stripslashes($_POST['subject'])); 
$message    = @trim(stripslashes($_POST['message'])); 
$to         = 'tradertarik@gmail.com';

$headers   = array();
$headers[] = "MIME-Version: 1.0";
$headers[] = "Content-type: text/plain; charset=iso-8859-1";
$headers[] = "From: {$name} <{$from}>";
$headers[] = "Reply-To: <{$from}>";
$headers[] = "Subject: {$subject}";
$headers[] = "X-Mailer: PHP/".phpversion();

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

我需要帮助找出问题所在。我检查了其他问题并以某种方式回答了它对我没有帮助。提前致谢。

P.S. 我不确定是否有人需要表单 html 代码，但我认为添加它也很好。

    <div class="contact-form wow fadeIn" data-wow-duration="1000ms" data-wow-delay="600ms">
      <div class="row">
        <div class="col-sm-6">
          <form id="main-contact-form" name="contact-form" method="post" action="sendemail.php">
            <div class="row  wow fadeInUp" data-wow-duration="1000ms" data-wow-delay="300ms">
              <div class="col-sm-6">
                <div class="form-group">
                  <input type="text" name="name" class="form-control" placeholder="Name" required>
                </div>
              </div>
              <div class="col-sm-6">
                <div class="form-group">
                  <input type="email" name="email" class="form-control" placeholder="Email Address" required>
                </div>
              </div>
            </div>
            <div class="form-group">
              <input type="text" name="subject" class="form-control" placeholder="Subject" required>
            </div>
            <div class="form-group">
              <textarea name="message" id="message" class="form-control" rows="4" placeholder="Enter your message" required></textarea>
            </div>                        
            <div class="form-group">
              <button type="submit" class="btn-submit">Send Now</button>
            </div>
          </form>   
        </div>

Answer 1

您的$headers 参数不正确；它应该是 string 而不是 array。来自PHP manual :

String to be inserted at the end of the email header.

This is typically used to add extra headers (From, Cc, and Bcc). Multiple extra headers should be separated with a CRLF (\r\n). If outside data are used to compose this header, the data should be sanitized so that no unwanted headers could be injected.

您应该能够像这样解决问题:

mail($to, $subject, $message, implode("\r\n", $headers));
