PHP 表单无法正常工作

Question

我的网站上有一个 PHP 表单，并且已成功运行。问题是它会向我的 HTML 文件发回发生错误的信息。我已经检查了 webmail 中的消息，它们都可以通过。

我认为这可能与使用 XAMPP 的控制台中显示的这一行有关：

Warning</b>:  mail() expects parameter 3 to be string, object given in 

mail('emails.contactus', $data , function($message) use ($toEmail, $toName, $fromEmail, $fromName, $subject)
    {
        $message->to($toEmail, $toName);

        $message->from($fromEmail, $fromName);

        $message->subject($subject);
    });

我也可以看到这个错误：

Undefined variable: data in

我没有邮件服务器，所以很难在 XAMPP 上进行全面调试。但是使用实时站点，邮件会通过。

HTML：

<div class="col-md-8 contact-form-wrapper">

                <div class="alert alert-style-1 information-box-home success-alert">
                  <div class="alert-icon"><i class="ico-ok"></i></div><!-- end of alert thumb -->
                  <div class="alert-contents">
                    <h6 class="alert-title">Success Message</h6>
                    <p>Thank you for contacting us, you will hear from us soon!</p>
                  </div><!-- end of alert contents -->
                </div><!-- end of alert -->

                </form><!-- end of contact form -->
              </div><!-- end of contact form wrapper -->

 <!-- Ajax Contact Form -->
      jQuery(document).ready(function($){
        // send message
        var form = $(".contact-form");
        $('.fail-alert').hide();
        $('.success-alert').hide();

        form.on( "submit", function( event ) { 
          $(".contact-btn").button('loading');

          event.preventDefault();

          $.ajax({
            type: "POST",
            url: form.attr( 'action' ),
            data: form.serialize(),
            success: function( response ) {
              console.log(response)
              if(response == "success"){
                $('.fail-alert').slideUp();
                $('.success-alert').slideDown();
              }
              else{
                $('.success-alert').slideUp();
                $('.fail-alert').slideDown();
              }
              console.log( response );
              $(".contact-btn").button('reset');
            }
          });

        });
      });

PHP：

<?php

if(!isset($_POST['submit'])) {

    $fromEmail      =  strip_tags($_POST['contact-email']);
    $fromName       =  strip_tags($_POST['contact-name']);

    $themessage     =  $themessage."The Sender Is ( ".$fromName." )" ;

    $toEmail = 'email@email.com';
    $toName = 'Name';
    $subject = 'Enquiry';

    mail('emails.contactus', $data , function($message) use ($toEmail, $toName, $fromEmail, $fromName, $subject)
    {
        $message->to($toEmail, $toName);

        $message->from($fromEmail, $fromName);

        $message->subject($subject);
    });

$headers = 'From:' .$fromName . "\r\n" .
    'Reply-To:' .$fromEmail. "\r\n" .
    'X-Mailer: PHP/' . phpversion();

if(mail($toEmail, $subject, $themessage, $headers))
{
      // Send
echo "success";

}
else{ echo "An error has be occured"; 

}
}

Answer 1

$data 未在您的示例代码中定义，您将其作为第二个参数传递，第二个参数应该是主题行，不确定您是否在页面前面设置了它，而您只是没有包括在这里？

您可以使用如下占位符对其进行测试：

$data = 'My subject line';

Answer 2

您的脚本有一些问题。

您调用了 mail 函数两次，日志中出现的错误来自您第一次调用 mail 时使用未定义的变量作为第二个参数和不正确的第三个参数类型：

mail('emails.contactus', $data , function($message) use ($toEmail, ...)
{
    $message->to($toEmail, $toName);

    $message->from($fromEmail, $fromName);

    $message->subject($subject);
});

由于该错误只是一个警告，因此脚本会继续并通过您必须向 mail() 的第二次调用发送邮件：

if(mail($toEmail, $subject, $themessage, $headers))

我怀疑您想完全删除第一个 mail() 调用，它看起来应该是对其他一些恰好也称为邮件的函数的调用（或者您没有将它的名称更改为正确的）
