Question

我正在尝试编写一个页面，用户可以在其中发送电子邮件和附件。我想我差不多了。现在我收到了电子邮件，但附件在filesize中是空的，或者当我尝试打开它时，我收到一条消息，说它无法打开。任何帮助表示赞赏。

    function valid_email($Email)
{
    //new regex, didn't give me any errors...might be a bit more exact
  if (ereg('^[_a-zA-Z0-9-]+(\.[_a-zA-Z0-9-]+)*@[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*\.(([0-9]{1,3})|([a-zA-Z]{2,3})|(aero|coop|info|museum|name))$', $Email) != false)
    return true;
  else 
    return false;
}

function sendEmail($email){
    return  mail ($email['to'], $email['subject'], $email['message'], $email['headers']);
}


if ( strlen($_FILES['Resume_File']['name']) > 0 )
{   // If a file was uploaded, do some processing
    $filename = preg_replace('/[^a-zA-Z0-9._-]/', '', $_FILES['Resume_File']['name']);
    $filetype = $_FILES["Resume_File"]["type"];
    $filesize = $_FILES["Resume_File"]["size"];
    $filetemp = $_FILES["Resume_File"]["tmp_name"]; 
    $ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);

    if ( !preg_match('/\.(doc|docx|odt|pdf|rtf|txt)/i', $ext) )
    {   $errors++;
        $errorLog .= "Upload filetype not supported.";
    }
    else if ( $filesize > 2000000 )
    {   $errors++;
        $errorLog .= "File size too high, up to 2MB is allowed.";
    }
    else
    {   // Looks like the file is good, send it with the email
        //$fp = fopen($filetemp, "rb");
        //$file = fread($fp, $filesize);
        //$file = chunk_split(base64_encode($file));

        //$email['headers'] .= "\n--{$num}\n";
        //$email['headers'] .= "Content-Type:{$filetype}";
        //$email['headers'] .= "name={$filename}r\n";
        //$email['headers'] .= "Content-Disposition: attachment; ";
        //$email['headers'] .= "filename={$filename}\n";
        //$email['headers'] .= "{$file}";

    }
}

// get posted data into local variables
$fname = trim(stripslashes($_POST['fname']));
$lname = trim(stripslashes($_POST['lname']));
$emailAddress = trim(stripslashes($_POST['email']));
$company = trim(stripslashes($_POST['company'])); 
$information = trim(stripslashes($_POST['information']));
$subject = trim(stripslashes($_POST['subject']));
$title = trim(stripslashes($_POST['title']));

//setup email
$to = 'me@me.com';
$subject = "Resume Submission";

$headers = "From: {$fname} {$lname} <{$emailAddress}>\r\n";

// prepare email body text
$message = "First Name: {$fname} <br>";
$message .= "Last Name: {$lname} <br>";
$message .= "Email: {$emailAddress} <br>";
$message .= "Title: {$title} <br><br>";
$message .= "Comments: {$information}";

if ( $errors == 0 ) {
    // Attachment headers

    //$to = "myemail@mydomain.com";
    //$from = "Website <website@mydomain.com>";
    //$subject = "Test Attachment Email";

    $separator = md5(time());

    // carriage return type (we use a PHP end of line constant)
    $eol = PHP_EOL;

    // attachment name
    //$filename = "document.pdf";

    //$pdfdoc is PDF generated by FPDF
    $attachment = chunk_split(base64_encode($pdfdoc));

    // main header
    $headers .= "From: ".$from.$eol;
    $headers .= "MIME-Version: 1.0".$eol; 
    $headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"";

    // no more headers after this, we start the body! //

    $body = "--".$separator.$eol;
    $body .= "Content-Transfer-Encoding: 7bit".$eol.$eol;
    $body .= "This is a MIME encoded message.".$eol;

    // message
    $body .= "--".$separator.$eol;
    $body .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol;
    $body .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
    $body .= $message.$eol;

    // attachment
    $body .= "--".$separator.$eol;
    $body .= "Content-Type: application/octet-stream; name=\"".$filename."\"".$eol; 
    $body .= "Content-Transfer-Encoding: base64".$eol;
    $body .= "Content-Disposition: attachment".$eol.$eol;
    $body .= $attachment.$eol;
    $body .= "--".$separator."--";

}



//sendEmail($email);

// validation

if ( $errors == 0 ) {

    if (valid_email($emailAddress) && $fname != "" && $lname != "") { //if return is true...
        mail($to, $subject, $body, $headers);
        echo 0; //Success
    }else { //otherwise
        echo 1; //Error
    }

} else {
    echo 1; //Error
}

我正在使用我在这里找到的部分代码

PHP mail() attachment problems

谢谢！

Answer 1

PHP的mail()功能非常差，特别是在尝试添加附件等高级功能时。它最适合用于最基本的“向网站管理员发送通知电子邮件”类型的电子邮件，即使这样，它也不总是最好的解决方案。

我建议放弃任何使用mail()函数本身的尝试，而是转而使用一个不错的PHP邮件程序类，例如适当命名的phpMailer。

phpMailer使得从PHP创建电子邮件变得容易。我拥有您可能想要的所有功能，包括轻松添加附件，编写HTML电子邮件等等。

但关于phpMailer的最好的事情是，它消除了浪费数十行代码格式化电子邮件标题的所有需要。分隔符和mime类型的所有内容都缩减为几行简单的代码。易于阅读，易于维护，并且不太可能有错误。你全面赢了。

//$pdfdoc is PDF generated by FPDF
    $attachment = chunk_split(base64_encode($pdfdoc));

$ pdfdoc未在页面中的任何位置提及。我认为这是问题：|
