PHP邮件功能不发送附件

Question

我正试图发送一封带有附件的电子邮件，我的代码如下，让我知道我是否正在做遗漏的东西或做错了什么

<?php
    function mail_attachment( $filename, $path, $mailto, $from_mail, $from_name, $replyto, $subject, $message ) {
        $file = $path. "/" .$filename;
        $file_size = filesize($file);
        $handle = fopen($file, "r");
        $content = fread($handle, $file_size);
        fclose($handle);
        $content = chunk_split(base64_encode($content));
        $separator = md5(uniqid(time()));
        $eol = PHP_EOL;
        $header = "From: ".$from_name." <[e-mail]>".$from_mail. $eol;
        $header .= "Reply-To: ".$replyto.$eol;
        $header .= "MIME-Version: 1.0".$eol;
        $header .= "Content-Type: multipart/mixed; boundary="".$separator. """ . $eol . $eol;
        $header .= "Content-Transfer-Encoding: 7bit" . $eol;
        $header .= "--".$separator. $eol;
        $header .= "Content-Type: text/plain; charset="iso-8859-1"" . $eol;
        $header .= "Content-Transfer-Encoding: 8bit" . $eol . $eol;
        $header .= $message. $eol . $eol;
        $header .= "--".$separator. $eol;
        $header .= "Content-Type: application/octet-stream; name="".$filename. $eol; // use different content types here
        $header .= "Content-Transfer-Encoding: base64".$eol;
        $header .= "Content-Disposition: attachment; filename="".$filename. $eol;
        $header .= $content. $eol;
        $header .= "--".$separator."--";
        ob_start(); //Turn on output buffering 
        if( mail( $mailto, $subject, "", $header ) ) {
            echo "mail send ... OK"; // or use booleans here
        } else {
            echo "mail send ... ERROR!";
        }
    }
    if( isset($_REQUEST['FindDealer']) ){
        $my_file = "pdf.pdf";
        $my_path = "/";
        $my_name = " Find Dealer @ flowsleeve";
        $my_mail = "[e-mail]";
        $my_replyto = "[e-mail]";
        $my_subject = "Find Dealer @ flowsleeve";
        $my_message = "Hallo,rndoPlease find Attached PDF For Dealers";
        mail_attachment( $my_file, $my_path, $my_mail, $my_name, $my_replyto, $my_subject, $my_message );
        header("Location: index.php#section8");
        exit();
    }
?>

use $mail-> addatattachment ($path);用这个比较好。

您可以从https://github.com/PHPMailer/PHPMailer获取phpmailer文件

<?php
require("class.phpmailer.php");
$mail = new PHPMailer();
$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp1.example.com;smtp2.example.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = '[e-mail]';                 // SMTP username
$mail->Password = 'secret';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;                                    // TCP port to connect to
$mail->setFrom('[e-mail]', 'Mailer');
$mail->addAddress('[e-mail]', 'Joe User');     // Add a recipient
$mail->addAddress('[e-mail]');               // Name is optional
$mail->addReplyTo('[e-mail]', 'Information');
$mail->addCC('[e-mail]');
$mail->addBCC('[e-mail]');
$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
$mail->isHTML(true);                                  // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
?>

这里有很多东西需要消化，但下面这行看起来不对。

$header = "From: ".$from_name." <[e-mail]>".$from_mail. $eol;

解析后，将显示为:

 "From: [e-mail] <[e-mail]>Find Dealer @ flowsleevern"

回复地址也是错误的，请参阅标题的完整打印输出，以了解我的意思。

提示:为了方便起见，我建议使用命名为与提供给函数mail_attachment ~ I的参数相同继续计算哪个参数引用了哪个变量

整个头部看起来像这样:

From: [e-mail] <[e-mail]>Find Dealer @ flowsleeve
Reply-To: Find Dealer @ flowsleeve
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="2642aff44ba290c53e0574e15444e12f"
Content-Transfer-Encoding: 7bit
--2642aff44ba290c53e0574e15444e12f
Content-Type: text/plain; charset="iso-8859-1"
Content-Transfer-Encoding: 8bit

--2642aff44ba290c53e0574e15444e12f
Content-Type: application/octet-stream; name="pdf.pdf
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="pdf.pdf

--2642aff44ba290c53e0574e15444e12f--

从以前处理附件的经验来看，格式是至关重要的——它必须在行结尾方面完全正确，否则就会失败。一些可能有帮助的指针:

• 边界前应该只有一行。
• 最后一个边界后面应该有2个破折号。
• 有两个地方的Content-Transfer-Encoding需要有一个新的行。

另外，我忘了提到你调用函数mail_attachment有7个参数，但函数有8个参数。在函数调用中似乎没有提供的是$from_mail
