PHP mail():发送附件，但不发送正文

Question

我看到过类似的问题，但没有直接涉及主题…

我有一个多部分邮件脚本与附件。附件可以正常发送，但是主体文本(由表单填充)没有发送。我试着将附件功能注释掉后发送，表单元素通过了。我的代码是:

if (empty($_POST['RadioGroup1'])){
    echo "PLease select a version of message";
} else {$selected_msg = $_POST['RadioGroup1'];} 
if (isset($_FILES) && (bool) $_FILES){
    $files = array();
// Check for attachments
    $questions = $_POST['questions'];   
//loop through all the files
  foreach($_FILES as $name=>$file){
// define the variables
    $file_name = $file['name'];
    $temp_name = $file['tmp_name'];
//check if file type allowed
    $path_parts = pathinfo($file_name);
//move this file to server
    $server_file = "reports/$path_parts[basename]";
    move_uploaded_file($temp_name, $server_file);
//add file to array of file
    array_push($files,$server_file);
}
// define mail var
$to   =  $email;
$from = "[server]";
$subject    = "Closed Case:  $case_id $casename";
$headers    = "From: $from";
//define boundary
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
// Header know about boundary
 $headers .= "nMIME-Version: 1.0n";
 $headers .= "Content-Type: multipart/mixed;n";
 $headers .= " boundary="{$mime_boundary}""; 
// Define plain text mail
$message .= "--{$mime_boundary}n";
$message .= "Content-Type: text/html; charset="iso-8859-1"n";
$message .= "Content-Transfer-Encoding: 7bitrn" . $message . "rn"; 
$message .= "--{$mime_boundary}n";
// preparing attachments
foreach($files as $file){
    $aFile = fopen($file, "rb");
    $data = fread($aFile,filesize($file));
    fclose($aFile);
    $data = chunk_split(base64_encode($data));
    $message .= "Content-Type: {"application/octet-stream"}n";
    $message .= " name="$file"n";
    $message .= "Content-Disposition: attachment;n";
    $message .= " filename="$file"n";
    $message .= "Content-Transfer-Encoding: base64nn" . $data . "nn";
    $message .= "--{$mime_boundary}n";
} // END foreach attachment
    $message .= $questions;
    $message .= $selected_msg;

 $ok = @mail($to, $subject, $message, $headers); 
if ($ok) { 
    echo "<p class="success">mail sent to $to!</p>";

脚本运行无错误，并发送文件附件或正文文本。任何见解将不胜感激。

Answer 1

不从内部调用表单变量

$message .= $questions; .

$message .= $selected_msg;
将变量硬编码到$message.=


像——$message .= "Content-Transfer-Encoding: 7bitrn" . $questions . "rn" . $selected_msg . "rn";

如果您喜欢在电子邮件中同时添加文本和附件，则使用下面的代码

$bodyMeaasge = 'Your Body Meaasge';
$filename = yourfile.pdf;
$path   =  '../';
$mpdf->Output($path.$filename,'F'); 
$file = $path . "/" . $filename;
$to = "[e-mail]";
$subject = "My Subject";
$random_hash = md5(date('r', time()));
$headers = "From:[e-mail]" .
           "X-Mailer: PHP" . phpversion() . "rn" .
           "MIME-Version: 1.0rn";
$headers .= "Content-Type: multipart/mixed; boundary = $random_hashrnrn";
if(file_exists($file))
{
    $content = file_get_contents($file);
    $content = chunk_split(base64_encode($content));
    //plain text 
    $body = "--$random_hashrn";
    $body .= "Content-Type: text/html; charset=ISO-8859-1rn";
    $body .= "Content-Transfer-Encoding: base64rnrn"; 
    $body .= chunk_split(base64_encode($bodyMeaasge)); 
    //attachment
    $body .= "--$random_hashrn";
    $body .="Content-Type: application/octet-stream; name=".$filename."rn";
    $body .="Content-Disposition: attachment; filename=".$filename."rn";
    $body .="Content-Transfer-Encoding: base64rn";
    $body .="X-Attachment-Id: ".rand(1000,99999)."rnrn"; 
    $body .= $content;
}else{
    //plain text 
    $body = "--$random_hashrn";
    $body .= "Content-Type: text/html; charset=utf-8rn"; // use different content types here
    $body .= "Content-Transfer-Encoding: base64rnrn"; 
    $body .= chunk_split(base64_encode($bodyMeaasge)); 
}
if (mail($to,$subject,$body,$headers)) {
  header("Location:".$url.'&success=successfully mail send.');
} else {
   header("Location:".$url.'&error=There was a problem sending the email.');
}
