我对带有生成附件并由 mail() 发送的邮件有疑问。我从这里使用示例 3 。

它工作正常。但是当我添加一些 php 定义（如：$somthing = $_POST['sth']）时，收到的电子邮件没有格式化，看起来像源代码。

<?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"

<?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();
// }
?>

并在邮件中：

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

--PHP-mixed-26680626f5767c87be4bc162d5e80e8e

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

这将导致您的标题中出现空行，因此标题将在From字段上结束，Content-type将被视为消息的正文。

您还缺少每个边界标记之前的空行。

更重要的是：

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

你认为它有什么作用？它返回 null 或空字符串，因此您从 POST 数据分配的每个变量都是空的。
