帶生成附件的郵件（）未在客戶端郵件上格式化

Question

我使用生成的附件發送郵件時發生問題，並通過郵件發送（）。 我使用here中的示例3。

它工作正常。但是當我添加一些php定義（如：$ somthing = $ _POST ['sth']）時，到達的電子郵件沒有格式化，它看起來像源代碼。

<?php 
    //session_start(); 
    include('funkcje.php'); 
    //$db=polaczMy(); 
    $nazwa = uzupelnij($_POST['nazwa']); 
    $vorname= uzupelnij($_POST['vorname']); 
    $strasse = uzupelnij($_POST['strasse']); 
    $kod = uzupelnij($_POST['kod']); 
    $tel = uzupelnij($_POST['tel']); 
    $mail = uzupelnij($_POST['mail']); 
    $datum_od = uzupelnij($_POST['datum_od']); 
    $datum_to = uzupelnij($_POST['datum_to']); 
    $ort = uzupelnij($_POST['ort']); 
    $zeit = uzupelnij($_POST['zeit']); 
    $mietteilung = uzupelnij($_POST['mietteilung']); 
    $service = uzupelnij($_POST['service']); 

    function uzupelnij($przesyl){ 
     if(empty($przesyl)){ 
      $przesyl = ""; 
      return $przesyl; 
     } 
    } 

     $to = '***@***.net'; 
     $subject = 'Anfrage'; 
     $random_hash = md5(date('r', time())); 
     $headers = "From: ***@***.de\r\n"; 
$headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\""; 
     $attachment = "BEGIN:VCARD\nVERSION:3.0\nN:".$vorname.";;;;\nFN:".$vorname."\nORG:".$nazwa."\nADR;TYPE=work:;;".$strasse.";".$ort.";;;\nEMAIL;type=INTERNET;type=WORK;type=internet:".$mail."\nTEL;type=WORK;type=pref:".$tel."\nEND:VCARD"; 
     ob_start(); 
     ?> 
--PHP-mixed-<?php echo $random_hash; ?> 
Content-Type: multipart/alternative; boundary="PHP-alt-<?php echo $random_hash; ?>" 
--PHP-alt-<?php echo $random_hash; ?> 
Content-Type: text/plain; charset="iso-8859-1" 
Content-Transfer-Encoding: 7bit 
Hello World!!! 
This is simple text email message.

Content-Transfer-Encoding: 7bit 
<h2>Hello World!</h2> 
<p>This is something with <b>HTML</b> formatting.</p> 
--PHP-alt-<?php echo $random_hash; ?>-- 
--PHP-mixed-<?php echo $random_hash; ?>

Content-Transfer-Encoding: 7bit 
Content-Disposition: attachment 
<?php echo $attachment; ?> 
--PHP-mixed-<?php echo $random_hash; ?>-- 
<?php 
     //copy current buffer contents into $message variable and delete current output buffer 
     $message = ob_get_clean(); 
     //send the email 
     $mail_sent = @mail($to, $subject, $message, $headers); 
     //if the message is sent successfully print "Mail sent". Otherwise print "Mail failed" 
     echo $mail_sent ? "<span style=\"margin-top: 20px; font-size: 18px; font-weight: bold;\">Vielen Dank! Ihre Anfrage wurde versendet. Wir werden bald mit Ihnen Kontakt aufnehmen. </span>" : "Mail failed"; 
     //session_destroy(); 
// } 
?> 

，並在郵件：

Content-Type: multipart/mixed; boundary="PHP-mixed-26680626f5767c87be4bc162d5e80e8e" 

--PHP-mixed-26680626f5767c87be4bc162d5e80e8e

Answer 1

$headers = "From: ***@***.de\r\n"; 
$headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\""; 

這將導致你的頭空行，所以頭會在From場結束，Content-type將被視爲該郵件的正文。

您還在每個邊界標記之前缺少一條空行。

，更重要的是：

function uzupelnij($przesyl){ 
    if(empty($przesyl)){ 
     $przesyl = ""; 
     return $przesyl; 
    } 
} 

你怎麼看它？它返回null或空字符串，所以你從POST數據分配的每個變量都是空的。
