PHP 邮件发送除 pdf 之外的所有内容

Question

查看并尝试了所有方法，但似乎无法弄清楚这一点。我有一个表单，用户可以通过复选框选择他们想要的某些文件。这通过了，他们应该发送所有文件。一切正常，除了它不会发送任何 pdf 格式的文件。它发送所有其他格式，而不是 pdfs...

我正在使用下面的代码。它使用一个数组来保存文件名，我尝试只使用一个 pdf，但它仍然不起作用。想也许pdf太大了，所以我只用了一个小的单页，还是什么都没有。请帮忙！

<?
function mail_attachment($files, $path, $mailto, $from_mail, $from_name, $replyto,        $subject, $message) {
$uid = md5(uniqid(time()));

$header = "From: ".$from_name." <".$from_mail.">\r\n";
$header .= "Reply-To: ".$replyto."\r\n";
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
$header .= "This is a multi-part message in MIME format.\r\n";
$header .= "--".$uid."\r\n";
$header .= "Content-type:text/html; charset=iso-8859-1\r\n";
$header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$header .= $message."\r\n\r\n";


foreach ($files as $filename) { 

    $file = $path.$filename;
                $name = basename($file);
    $file_size = filesize($file);
    $handle = fopen($file, "r");
    $content = fread($handle, $file_size);
    fclose($handle);
    set_magic_quotes_runtime(0);

    $content = chunk_split(base64_encode($content));

    $header .= "--".$uid."\r\n";
    $header .= "Content-Type: application/octet-stream; name=\"".$filename."\"\r\n"; // use different content types here
    $header .= "Content-Transfer-Encoding: base64\r\n";
    $header .= "Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n";
    $header .= $content."\r\n\r\n";
}

$header .= "--".$uid."--";
return mail($mailto, $subject, "", $header);
}
?>

更新：尝试建议但同样的事情的 swiftmail。电子邮件的新实例工作正常，除非附加 pdf。所以这条线有效：

$message->attach(
Swift_Attachment::fromPath('file.docx')->setFilename('file.docx')
);

但这条线没有：

$message->attach(
Swift_Attachment::fromPath('file.pdf')->setFilename('file.pdf')
);

Answer 1

编辑：修改了一行代码，使用下面的原始代码：

改变：

$header .= "Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n";

到：

$header .= "Content-Type: application/pdf; filename=\"".$filename."\"\r\n\r\n";

新代码：

<?
function mail_attachment($files, $path, $mailto, $from_mail, $from_name, $replyto,        $subject, $message) {
$uid = md5(uniqid(time()));

$header = "From: ".$from_name." <".$from_mail.">\r\n";
$header .= "Reply-To: ".$replyto."\r\n";
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
$header .= "This is a multi-part message in MIME format.\r\n";
$header .= "--".$uid."\r\n";
$header .= "Content-type:text/html; charset=iso-8859-1\r\n";
$header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$header .= $message."\r\n\r\n";


foreach ($files as $filename) { 

    $file = $path.$filename;
                $name = basename($file);
    $file_size = filesize($file);
    $handle = fopen($file, "r");
    $content = fread($handle, $file_size);
    fclose($handle);
    set_magic_quotes_runtime(0);

    $content = chunk_split(base64_encode($content));

    $header .= "--".$uid."\r\n";
    $header .= "Content-Type: application/octet-stream; name=\"".$filename."\"\r\n"; // use different content types here

    $header .= "Content-Transfer-Encoding: base64\r\n";
    $header .= "Content-Type: application/pdf; filename=\"".$filename."\"\r\n\r\n";     $header .= $content."\r\n\r\n";
}

$header .= "--".$uid."--";
return mail($mailto, $subject, "", $header);
}
?>

附件不在标题中。他们应该只声明 MIME 标头

这是一个例子：

<?php
$sendto = "email@example.com";
$message = "Message here\r\n Hello, this is a test!!";

$filename = "file.pdf";
$handle = fopen($filename, 'rb');
$contents = fread($handle,filesize($filename));
fclose($handle);
$encoded = chunk_split(base64_encode($contents));

$seperator = md5(uniqid(time()));
$from = '"First Last" <username@domain.com>';
$header = '';
$header .= "From: $from\r\n";
$header .= "MIME-Version: 1.0\r\nContent-Type:"." multipart/mixed; boundary=\"$seperator\";\r\n";


$body.= "--$seperator\r\n";
$body.= "Content-Type: text/plain; charset=\"iso-8859-1\"\r\n";
$body.= "Content-Transfer-Encoding: 7bit\r\n\n";
$body.= $message."\r\n\n";

$body.= "--$seperator\r\n";
$body.= "Content-Type: application/pdf; name=\"file.pdf\"\r\n";
$body.= "Content-Transfer-Encoding: base64\r\n";
$body.= "Content-Disposition: attachment; filename=\"file.pdf\"\r\n\n";
$body.= $encoded."\r\n";
$body.= "--$seperator--\r\n";

mail($sendto,$subject, $body, $header);
?>

我也找到了这个脚本。 （经过测试）

看看你可以用$files数组做什么。

<?php

// array with filenames to be sent as attachment

$files = array("image.jpg","file.pdf","file3.txt");
// $files = array("LakeRules.pdf","TermsConditions.pdf");
 
// email fields: to, from, subject, and so on
$to = "email@example.com";
$from = "email@example.com";
$cc = ""; 
$subject = "Files";
$message = "$emailBody";
$headers = "From: $from\r\n";
$headers .= "cc: $cc";
 
// 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/html; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n"; 
$message .= "--{$mime_boundary}\n";
 
// preparing attachments
for($i=0;$i<count($files);$i++){
if(is_file($files[$i])){
$message .= "--{$mime_boundary}\n";
$fp = @fopen($files[$i],"rb");
$data = @fread($fp,filesize($files[$i]));
@fclose($fp);
$data = chunk_split(base64_encode($data));
$message .= "Content-Type: application/octet-stream; name=\"".basename($files[$i])."\"\n" .
"Content-Description: ".basename($files[$i])."\n" .
"Content-Disposition: attachment;\n" . " filename=\"".basename($files[$i])."\"; size=".filesize($files[$i]).";\n" .
"Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
}
}
$message .= "--{$mime_boundary}--";
//}

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

?>

好吧，仍然不知道为什么我的脚本不能与 pdf 一起使用，但我终于找到了解决方案。在我使用 SMTP 之前，Swiftmailer 仍然存在问题，然后它运行良好。如果有人对为什么会这样有任何见解，我很想知道答案，但至少它是有效的！感谢大家的帮助！
