邮件附件问题 - 为什么我没有正确的文件？ [英] mail attachment issue - why do i dont get the file properly?

问题描述

我尝试创建一个表单，并提供上传文件的选项，并将其发送到我的电子邮件。
，例如用户可以将他的信息放在输入字段中，并添加一个文件，当用户提交文件时，我将把它全部寄给我的邮件。

这是我的代码：

 <？php 
 
 if（isset（$ _ FILES） &（（bool）$ _FILES）{
 
 $ allowedExtensions = array（pdf，doc，docx，gif，jpeg，jpg ， RTF， TXT）; 
 
 $ files = array（）; 
 foreach（$ _ FILES as $ name => $ file）{
 $ file_name = $ file ['name']; 
 $ temp_name = $ file ['tmp_name']; 
 $ file_type = $ file ['type']; 
 $ path_parts = pathinfo（$ file_name）; 
 $ ext = $ path_parts ['extension']; 
如果（！in_array（$ ext，$ allowedExtensions））{
 die（File $ file_name的扩展名为$ ext，不允许）; 
} 
 array_push（$ files，$ temp_name）; 
} 
 
 //电子邮件字段：to，from，subject等等
 $ to =[e-mail]; 
 $ from = $ _POST ['sender_email']; 
 $ subject =test attachment; 
 $ message =here ya go; 
 $ headers =From：$ from; 
 
 //边界
 $ semi_rand = md5（time（））; 
 $ mime_boundary === Multipart_Boundary_x {$ semi_rand} x; 
 
 //附件标题
 $ headers。=\\\
MIME-Version：1.0\\\
。 Content-Type：multipart / mixed; \\\
。 boundary = \{$ mime_boundary} \; 
 
 // multipart boundary 
 $ message =这是MIME格式的多部分消息.\\\
\\\
。  -  {$ mime_boundary} \\\
。 Content-Type：text / plain; charset = \iso-8859-1\\\\
。 Content-Transfer-Encoding：7bit\\\
\\\
。 $消息。 \\\
\\\
; 
 $ message。= -  {$ mime_boundary} \\\
; 
 
 //准备附件
（$ x = 0; $ x< count（$ files）; $ x ++）{
 $ file = fopen（$ files [$ x ]， RB）; 
 $ data = fread（$ file，filesize（$ files [$ x]））; 
 fclose（$ file）; 
 $ data = chunk_split（base64_encode（$ data））; 
 $ message。=Content-Type：{\application / octet-stream\}; \\\
。 name = \$ files [$ x] \\\\
。 
Content-Disposition：attachment; \\\
。 filename = \$ files [$ x] \\\\
。 
Content-Transfer-Encoding：base64\\\
\\\
。 $数据。 \\\
\\\
; 
 $ message。= -  {$ mime_boundary} \\\
; 
} 
 
 //发送
 
 $ ok = @mail（$ to，$ subject，$ message，$ headers）; 
 if（$ ok）{
 echo< p>邮件发送到$到！< / p>; 
} else {
 echo< p>邮件无法发送！< / p>; 
} 
} 
 
？> 
  

（和文件到达命名为... tmp / phpcVjk4w /）任何建议？

解决方案

更改：

  array_push ，$ temp_name）; 
  

to：

 code> array_push（$ files，array（'temp_name'=> $ temp_name，'file_name'=> $ file_name））; 
  

并更改：

 （$ x = 0; $ x< count（$ files）; $ x ++）{
 $ file = fopen（$ files [$ x] RB）; 
 $ data = fread（$ file，filesize（$ files [$ x]））; 
 fclose（$ file）; 
 $ data = chunk_split（base64_encode（$ data））; 
 $ message。=Content-Type：{\application / octet-stream\}; \\\
。 name = \$ files [$ x] \\\\
。 
Content-Disposition：attachment; \\\
。 filename = \$ files [$ x] \\\\
。 
Content-Transfer-Encoding：base64\\\
\\\
。 $数据。 \\\
\\\
; 
 $ message。= -  {$ mime_boundary} \\\
; 
} 
  

To：

<$ （$ x = 0; $ x< count（$ files）; $ x ++）{
$ temp_name = $ files [$ x ] [ 'temp_name']; //临时文件位置
$ file_name = $ files [$ x] ['file_name']; // filename
$ file = fopen（$ temp_name，rb）;
$ data = fread（$ file，filesize（$ temp_name））;
fclose（$ file）;
$ data = chunk_split（base64_encode（$ data））;
$ message。=Content-Type：{\application / octet-stream\}; \\\
。 name = \$ file_name\\\\
。
Content-Disposition：attachment; \\\
。 filename = \$ file_name \\\\
。
Content-Transfer-Encoding：base64\\\
\\\
。 $数据。 \\\
\\\
;
$ message。= - {$ mime_boundary} \\\
;
}

这里的区别是将文件名拖到$ files数组中，临时文件位置。您需要两者，服务器上的文件在哪里，以及上传文件的名称。

i try to create a form with a option to upload files and to get it to my email . for example that a user can put his info in the input fields and to add a file and when the user submit it i will get it all to my mail.

this is my code :

<?php

if(isset($_FILES) && (bool) $_FILES) {

$allowedExtensions = array("pdf","doc","docx","gif","jpeg","jpg","png","rtf","txt");

$files = array();
foreach($_FILES as $name=>$file) {
    $file_name = $file['name']; 
    $temp_name = $file['tmp_name'];
    $file_type = $file['type'];
    $path_parts = pathinfo($file_name);
    $ext = $path_parts['extension'];
    if(!in_array($ext,$allowedExtensions)) {
        die("File $file_name has the extensions $ext which is not allowed");
    }
    array_push($files,$temp_name);
}

// email fields: to, from, subject, and so on
$to = "[e-mail]";
$from = $_POST['sender_email']; 
$subject ="test attachment"; 
$message = "here ya go";
$headers = "From: $from";

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

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

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

// preparing attachments
for($x=0;$x<count($files);$x++){
    $file = fopen($files[$x],"rb");
    $data = fread($file,filesize($files[$x]));
    fclose($file);
    $data = chunk_split(base64_encode($data));
    $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$files[$x]\"\n" . 
    "Content-Disposition: attachment;\n" . " filename=\"$files[$x]\"\n" . 
    "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
    $message .= "--{$mime_boundary}\n";
}

// send

$ok = @mail($to, $subject, $message, $headers); 
if ($ok) { 
    echo "<p>mail sent to $to!</p>"; 
} else { 
    echo "<p>mail could not be sent!</p>"; 
} 
   }    

   ?>

(and file arrive named... tmp/phpcVjk4w/ ) any suggestions?

解决方案

Change:

array_push($files,$temp_name);

to:

array_push($files, array('temp_name' => $temp_name, 'file_name' => $file_name));

And change:

// preparing attachments
for($x=0;$x<count($files);$x++){
    $file = fopen($files[$x],"rb");
    $data = fread($file,filesize($files[$x]));
    fclose($file);
    $data = chunk_split(base64_encode($data));
    $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$files[$x]\"\n" . 
    "Content-Disposition: attachment;\n" . " filename=\"$files[$x]\"\n" . 
    "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
    $message .= "--{$mime_boundary}\n";
}

To:

// preparing attachments
for($x=0;$x<count($files);$x++){
    $temp_name = $files[$x]['temp_name']; // temporary file location
    $file_name = $files[$x]['file_name']; // filename
    $file = fopen($temp_name,"rb");
    $data = fread($file,filesize($temp_name));
    fclose($file);
    $data = chunk_split(base64_encode($data));
    $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$file_name\"\n" . 
    "Content-Disposition: attachment;\n" . " filename=\"$file_name\"\n" . 
    "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
    $message .= "--{$mime_boundary}\n";
}

The difference here is pulling the filename into the $files array along with the temporary file location. You need both, where is the file on the server, and what is the name of the file when uploaded.
