这是表单的 php 代码：

<?php
if(isset($_POST['email'])) {

    // CHANGE THE TWO LINES BELOW
    $email_to = "kennis_16@yahoo.com";        

    $email_subject = "form submission";

    function died($error) {
        // your error code can go here
        echo "We are sorry, Your comment couldn't be submitted. Please provide solution to error(s) below.<br /><br />";

        echo $error."<br /><br />";

        echo "Please go back and fix these errors.<br /><br />";
        die();
    }

    // validation expected data exists
    if(!isset($_POST['author']) ||
        !isset($_POST['email']) ||
        !isset($_POST['url']) ||

        !isset($_POST['comment'])
        )

    $error_message = "";
        $string_exp = "/^[A-Za-z .'-]+$/";
  if(!preg_match($string_exp,$commentName)) {
    $error_message .= 'The Name is empty, or does not appear to be valid.<br />';
  }
    $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';

  }

        $string_exp = "/^[0-9+().-]+$/";

    }

    $email_message .= "commentName: ".clean_string($commentName)."\n";

// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);  
?>

这是 HTML 代码：

【解决方案1】：

您不能将图像分配给变量并通过邮件发送。你需要做几个步骤

检查图片格式是否有效（jpg、png...）
然后上传到服务器
然后用附件发送

在<form> 中你应该使用enctype="multipart/form-data"

<form id="" method="post" action="" enctype="multipart/form-data">

检查图片格式是否有效

<?php
    $target_dir = "uploads/";
    $target_file = $target_dir . basename($_FILES["photo"]["name"]);
    $status = 1;
    $FileType = pathinfo($target_file,PATHINFO_EXTENSION);

// Allow certain file formats
    if($FileType != "jpg" && $FileType != "png" && $FileType != "jpeg")
    {
        echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
        $status = 0;
    }


// Check if $status is set to 1
    if ($status == 1) 
    {
        // if everything is ok, try to upload file
        if (move_uploaded_file($_FILES["photo"]["tmp_name"], $target_file)) 
        {
            echo "The file has been uploaded.";
        } else 
        {
            echo "Sorry, there was an error uploading your file.";
        }    

    } 
    else 
    {
        echo "Sorry, your file was not uploaded.";
    }
?>

然后获取文件路径

<?php

$path = "uploads/".$_FILES["photo"]["tmp_name"];

?>

在邮件中

<img src="<?php echo $path ;?>" alt="">

将其包含在电子邮件标题中

$header = "From:".$email_from."\nMIME-Version: 1.0\nContent-Type: text/html; charset=utf-8\n";

非常感谢@阿卜杜拉。请您花点时间解释一下我可以如何或将这个新代码添加到我现有的代码中。在此先感谢您，我等待您的回复
另外，我尝试通过添加 enctype="multipart/form-data"> 来遵循您的指示，这是用户提交表单时的响应：对不起，您的评论无法提交。请提供以下错误的解决方案。很抱歉，您提交的表单似乎有问题。请返回并修复这些错误。

【解决方案2】：

这里是完整的解决方案。我简单地保留了它。您可以稍后添加其他代码。我已经测试了代码并且它工作得很好。

PHP 部分

<?php
$error_message = "";
if(isset($_POST['send'])) {


// CHANGE THE TWO LINES BELOW
$email_to = "kennis_16@yahoo.com";   


$email_subject = "form submission";

$commentName = $_POST['author']; // required
$email_from = $_POST['email']; // required
$website = $_POST['url']; // required
//$photo = $_POST['photo'];

$photoname=$_FILES['photo']['name'];
$tmp_name=$_FILES['photo']['tmp_name'];
$comments= $_POST['comment']; // required

if($commentName==""){
    echo "Empty author name";
}else if($email_from==""){
    echo "Empty email";
}
else{
 //create a folder name called img
 $destinationpath="img/".$photoname;
 $moveimage=move_uploaded_file($tmp_name,$destinationpath);


 if(!$moveimage){
  die("Error in uploading");
 }

  $message = "Form details below\n\n";


  $message .= "commentName: ".$commentName."\n";
  $message .= "email: ".$email_from."\n";
  $message .= "website: ".$website."\n";

  $message .= "comments: ".$comments."\n";


    // boundary 
    $semi_rand = md5(time()); 
    $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";



     // preparing attachments            
        $file = fopen($destinationpath,"rb");
        $f_contents = fread($file,filesize($destinationpath));
        $f_contents = chunk_split(base64_encode($f_contents));
       fclose($file);
        # Get a random 32 bit number using time() as seed.
     $num = md5( time() );

    # Define the main headers.
    $header = "From:xyz@somedomain.com\r\n";
    $header .= "MIME-Version: 1.0\r\n";
   $header .= "Content-Type: multipart/mixed; ";
   $header .= "boundary=$num\r\n";
   $header .= "--$num\r\n";

   # Define the message section
   $header .= "Content-Type: text/plain\r\n";

   $header .= "$message\r\n";
   $header .= "--$num\r\n";

   # Define the attachment section
   $header .= "Content-Type:  multipart/mixed; ";
   $header .= "name=\"$photoname\"\r\n";
   $header .= "Content-Transfer-Encoding:base64\r\n";
   $header .= "Content-Disposition:attachment; ";
   $header .= "filename=\"$photoname\"\r\n\n";
   $header .= "$f_contents \r\n";
   $header .= "--$num--";

      mail($email_to, $email_subject, $message, $header); 
           }
         ?>

      <!-- place your own success html below -->

   <h2>Your comment will be reviewed before posting within 48hours.
  </h2>
  <?php
   }

  ?>

还有body标签里面的html部分

  <!-- Comment Form -->
  <div id="respond" class="eleven columns row alpha">
  <h4>Leave a comment</h4>
  <form id="replyform" method="post" action="" enctype="multipart/form-data">
  <div class="input_cm_wrapper">
  <h6 for="commentName">Name *</h6>
  <input type="text" name="author" id="reply_name" class="required"/>
</div>
<div class="input_cm_wrapper">
  <h6 for="email">Email Address *</h6>
  <input type="email" name="email" id="reply_email" class="required"/>
</div>
<div class="input_cm_wrapper last">
  <h6 for="website">Phone No. *</h6>
  <input type="text" name="url" id="reply_website" class="last"/>
</div>
<span class="clear"></span>
  <h6 for="commentsText">
  Message *   <span>&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp
  Upload Photo. * &nbsp&nbsp&nbsp
  <input type="file" name="photo" id="reply_photo" class="requiredfield"  required />
  </span> </h6>
<textarea name="comment" id="reply_message" class="requiredfield"></textarea>
<span class="clear"></span><br>
<button type="submit"  name="send">Send</button>
</form>
</div>

干杯
