Question

我通过php mail（）发送电子邮件。在那，我能够收到简单的（文本）邮件。当我附加文件时，我收到了电子邮件中的附件，但是当我尝试查看它时，该文件始终是空白的，即使它是PDF格式!!!请帮帮我。我的发送邮件页面的代码如下：

include_once("db_connect.php");
session_start();
error_reporting(16);
require_once('class.phpmailer.php');//Getting values from Session
$tot = $_SESSION['$tot'];
$from = $_SESSION['from'];
$message = $_SESSION['message'];
$subject = $_SESSION['subject'];
$full_nm = $_SESSION['firstnm']." ".$_SESSION['lastnm'];
$temp_passwd = $_SESSION['e_pwd'];
$email_use = $_SESSION['email'];

function send_mail($to, $message, $subject, $from, $temp_passwd, $full_nm, $email_use)
{
    $message_org      = nl2br($message);
    $mail             = new PHPMailer();
    $body             = $message_org;
    $mail->IsSMTP(); 
    $mail->SMTPAuth   = true;
    $mail->SMTPSecure = "ssl";
    $mail->AddAttachment("Uploads/file.pdf");
    $mail->ContentType = "mutlipart/alternative";
    $mail->Host       = "smtp.mail.yahoo.com";
    $mail->Port       = 465;
    $mail->Username   = $from;
    $mail->Password   = $temp_passwd;
    $mail->SetFrom($from, $full_nm);
    $mail->Subject    = $subject;
    $mail->MsgHTML($body);
    $address = $to;
    $mail->AddAddress($address, $address);

    if(!$mail->Send())
    {
        $err_send = "Mailer Error: " . $mail->ErrorInfo;
    }
        else
    {
        $err_send = "";
    }
}
foreach($tot as $to_trim)
{
    $to = trim($to_trim);
    send_mail($to, $message, $subject, $from, $temp_passwd, $full_nm, $email_use);
    echo $err_send;
}

The function AddAttachment in class.phpmailer.php is as follows:

public function AddAttachment($path, $name = '', $encoding = 'base64', $type = 'application/octet-stream') {
try {
  if ( !@is_file($path) ) {
    throw new phpmailerException($this->Lang('file_access') . $path, self::STOP_CONTINUE);
  }
  $filename = basename($path);
  if ( $name == '' ) {
    $name = $filename;
  }

  $this->attachment[] = array(
    0 => $path,
    1 => $filename,
    2 => $name,
    3 => $encoding,
    4 => $type,
    5 => false,  // isStringAttachment
    6 => 'attachment',
    7 => 0
  );

} catch (phpmailerException $e) {
  $this->SetError($e->getMessage());
  if ($this->exceptions) {
    throw $e;
  }
  echo $e->getMessage()."\n";
  if ( $e->getCode() == self::STOP_CRITICAL ) {
    return false;
  }
}
return true;
}

Answer 1

当您执行$ mail-＆gt; AddAttachment（“Uploads / file.pdf”）; 如果将添加附件放在“if file exists add attachment”子句中，文件是否不会被附加？我认为“Uploads / file.pdf”并不足够。

Answer 2

根据the documentation for this class，您应该能够指定该文件的相对路径。

尝试使用PHP测试在该行之前查看文件是否确实存在：

// Change this
$mail->AddAttachment("Uploads/file.pdf");

// To this...
$attachment = "Uploads/file.pdf";
$mail->AddAttachment($attachment);

// And then to this
$attachment = "Uploads/file.pdf";
if(!file_exists($attachment) && !file_exists(getcwd().'/'.$attachment)
{
    die(sprintf("attachment: %s does not exist", $attachment));
}
$mail->AddAttachment($attachment);

我提出了一个中间步骤，只是为了向您展示我的想法。

我没有测试过if语句，但想法是确保$attachment变量是有效的绝对（第一部分）或相对（第二部分）路径。

附加文件无法查看
