使用PHP通过HTML表单发送电子邮件附件

我在服务器上创建了“uploads”文件夹，用户在HTML表单上上传的文件可以很好地进入该文件夹。 接下来，我尝试从该文件夹中检索它并将其附加到电子邮件中，但这部分不起作用。 以下是我的PHP：

    <?php
$name = $_POST['name'];
$email = $_POST['email'];
$form_subject = $_POST['form_subject'];
$message = $_POST['message'];


//File upload

// Where the file is going to be placed 
$target_path = "uploads/";

/* Add the original filename to our target path.  
Result is "uploads/filename.extension" */
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']). 
    " has been uploaded";
} else{
    echo "There was an error uploading the file, please try again!";
}   

//End of file upload


$ip=@$REMOTE_ADDR;
$date=date("l, F j, Y, g:i a"); 

$to = "vlevsha@gmail.com";
$subject = "New data submitted!";
$body = "Here is the information submitted to 
www.polycysticliverdisease.com/html/pld_form.php 
from $ip on $date.\n\n
--------------------------------\n\n
name: $name \n\n
email address: $email \n\n
subject: $form_subject \n\n
comment: $message";
//mail($to, $subject, $body);

// Obtain file upload vars    
$fileatt      = $_FILES['uploadedfile']['tmp_name'];    
$fileatt_type = $_FILES['uploadedfile']['type'];    
$fileatt_name = $_FILES['uploadedfile']['name'];

if (is_uploaded_file($fileatt)) {    
 // Read the file to be attached ('rb' = read binary)    
 $file = fopen($fileatt,'rb');    
 $data = fread($file,filesize($fileatt));    
 fclose($file);

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

 // Add the headers for a file attachment    
 $headers .= "\nMIME-Version: 1.0\n" .    
             "Content-Type: multipart/mixed;\n" .    
             " boundary=\"{$mime_boundary}\"";

// Add a multipart boundary above the plain message    
 $message = "This is a multi-part message in MIME format.\n\n" .    
            "--{$mime_boundary}\n" .    
            "Content-Type: text/plain; charset=\"iso-8859-1\"\n" .    
            "Content-Transfer-Encoding: 7bit\n\n" .    
            $message . "\n\n";

// Base64 encode the file data    
 $data = chunk_split(base64_encode($data));

 // Add file attachment to the message    
 $message .= "--{$mime_boundary}\n" .    
             "Content-Type: {$fileatt_type};\n" .    
             " name=\"{$fileatt_name}\"\n" .    
             "Content-Disposition: attachment;\n" .    
             " filename=\"{$fileatt_name}\"\n" .    
             "Content-Transfer-Encoding: base64\n\n" .    
             $data . "\n\n" .    
             "--{$mime_boundary}--\n";    
}

// Send the message    
$ok = @mail($to, $subject, $body, $headers);    
if ($ok) {    
 echo "<p>Mail sent! Yay PHP!</p>";    
} else {    
 echo "<p>Mail could not be sent. Sorry!</p>";    
}

?>

这是我的HTML文件上载控件：

<input type="submit" name="submit" class="submit" />
<input type="file" name="uploadedfile" class="upload" />

谢谢大家!

我会用一些邮件库——也许吧。自己编程是不值得的（当然，如果你不是为了学习而编程）。

使用预构建的邮件程序包，如或。两者都可以轻松处理附件。

非常感谢！它工作得很好。我爱速递！但是，当我为我的电子邮件设置正文时，我混合使用了文本和变量：$message->setBody（'这是在$date从$ip提交到www.polycysticliverdisease.com/html/pld_form.php的信息。\n\n name:$name\n\n电子邮件地址：$email\n\n subject:$form_subject\n\n comment:$form_message，'text/html'）；所有变量都声明并分配了适当的值。但是它们和“\n\n”都作为文本的一部分出现在发送的电子邮件中，即它们不被识别为变量。为什么？@vlevsha因为你用的是单引号。使用双引号。谢谢，我甚至在看到你的答案之前就引用了。：）现在，我有一个更严重的问题：谢谢！我选择了斯威夫特梅勒。我就是喜欢！
