无法使用PHP在emain中发送附件文件

Question

使用此代码使用PHP在电子邮件中发送附件。

因此，我只收到了我的电子邮件，但我无法通过附件收到该邮件。

这是我的PHP代码：

<?php
if($_POST && isset($_FILES['attachment'])){   
$from_email = 'someone@gmail.com'; //sender email
$recipient_email = 'me@gmail.com'; //recipient email
$subject = 'Test mail'; //subject of email
$message = 'This is body of the message'; //message body 

$file_name = $_FILES['attachment']['name'];
$temp_name = $_FILES['attachment']['temp_name'];
$file_type = $_FILES['attachment']['type'];
$file_size = $_FILES['attachment']['size'];

//get base ext of file

$base = basename($file_name);
$extention = substr($base, strlen($base)-4, strlen($base));

//only these files type will allowed
$allowed_extentions = array(".doc", "docx", ".pdf", ".zip", ".png", ".xlsx");



/* check that file type is allowed  */ 

     if(in_array($extention, $allowed_extentions )) {

$user_email = filter_var($_POST["email"], FILTER_SANITIZE_EMAIL);

if($file_error>0)
{
    die('upload error');
}



/* things you need  */

$file = $temp_name ;
$content = chunk_split(base64_encode( file_get_contents($file) )) ;
$uid = md5(uniqid(time()));



    //header
    $header .= "MIME-Version: 1.0\r\n"; 
    $header .= "From:".$from_email."\r\n"; 
    $header .= "Reply-To: ".$user_email."" . "\r\n";
    $header .= "Content-Type: multipart/mixed; boundary = $boundary\r\n\r\n"; 

    /* declaring we  have multiple kinds of email */ 
    $header .= "Content-Type: multipart/mixed; boundary=\"" .$uid."\"\r\n\r\n";
    $header .= "This is multipart message in MIME formate.\r\n";             

    /* plain text part */ 
    $header .= "--".$uid."\r\n";
    $header .= "Content-Type:text/plain; charset=iso-8859-1\r\n";
    $header .= "Content-Transfer-Encoding : 7bit\r\n\r\n";
    $header .= $message."\r\n\r\n";

    /* file attachment  */ 
    $header .= "--".$uid."\r\n";
    $header .= "Content-Type: ".$file_type."; name=\"".$file_name."\"\r\n";
    $header .= "ContentTransfer-Encoding:base64\r\n";
    $header .= "Content-Disposition: attachment; filename=\"".$file_name."\"\r\n";
    $header .= $content."\r\n\r\n";

    require_once "Mail.php";

 /* mail setup recipients, subject etc */
 $name =  'sanju';       //$_POST['name'];
 $email =  $from_email ;     //         $_POST['email'];
 $subject = 'Test mail';   //$_POST['subject'];
 //$comments = 'This is body of the message';   //$_POST['message'];

  $recipients = 'me@gmail.com';

$header = array (
           'From' => "someone@gmail.com",
           'Content-type' => "text/html;charset=UTF-8",
           'Reply-To' => "someone@gmail.com",
           'To' => "contact@domain.com",

           );



 $mailmsg="Name : $name \n\n Email :$email  \n\n Message : $message   ";
 /* SMTP server name, port, user/passwd */
 $smtpinfo["host"] = "ssl://lnxind3.cloudhostdns.net";
 $smtpinfo["port"] = "465";
 $smtpinfo["auth"] = true;
 $smtpinfo["username"] = "contact@net-lytics.com";
 $smtpinfo["password"] = "sanjeev12@";
 /* Create the mail object using the Mail::factory method */
 $mail_object =& Mail::factory("smtp", $smtpinfo);
 /* Ok send mail */
 echo $mail_object->send($recipients, $header, $mailmsg);
 $msg = " Thank you for contacting us. .";;




 } else {
            echo " File type not allowed";
        }
}
?>
