attachment in sendmail form

Hej,

Jeg prøver at lave en mail formular som sender sender en mail til mig med en attachment som jeg har uploadet via formularen, men indtil videre sender den kun teksten, jeg kan ikke få den til at sende attachment.

Her er min kode:

<?php
function spamcheck($field)
  {
  //filter_var() sanitizes the e-mail
  //address using FILTER_SANITIZE_EMAIL
  $field=filter_var($field, FILTER_SANITIZE_EMAIL);

  //filter_var() validates the e-mail
  //address using FILTER_VALIDATE_EMAIL
  if(filter_var($field, FILTER_VALIDATE_EMAIL))
    {
    return TRUE;
    }
  else
    {
    return FALSE;
    }
  }

if (isset($_REQUEST['email']))
  {//if "email" is filled out, proceed

  //check if the email address is invalid
  $mailcheck = spamcheck($_REQUEST['email']);
  if ($mailcheck==FALSE)
    {
    echo "Invalid input";
    }
  else
    {//send email
    $email = $_REQUEST['email'] ;
    $subject = $_REQUEST['subject'] ;
    $message = $_REQUEST['message'] ;
	
	//Get the uploaded file information
	$name_of_uploaded_file =  basename($_FILES['uploaded_file']['name']);
	//get the file extension of the file
	$type_of_uploaded_file = substr($name_of_uploaded_file, strrpos($name_of_uploaded_file, '.') + 1);
	
	$size_of_uploaded_file = 
    $_FILES["uploaded_file"]["size"]/1024;//size in KBs
	
	//Settings 
	$max_allowed_file_size = 100; // size in KB 
	$allowed_extensions = array("jpg", "jpeg", "gif", "bmp");

	//Validations
	if($size_of_uploaded_file > $max_allowed_file_size ) 
{
  	$errors .= "\n Size of file should be less than $max_allowed_file_size";
}

	//------ Validate the file extension -----
	$allowed_ext = false;
	for($i=0; $i<sizeof($allowed_extensions); $i++) 
{ 
  	if(strcasecmp($allowed_extensions[$i],$type_of_uploaded_file) == 0)
  {
    $allowed_ext = true;    
  }
}

	if(!$allowed_ext)
{
 	 $errors .= "\n The uploaded file is not supported file type. ".
  	" Only the following file types are supported: ".implode(',',$allowed_extensions);
}

	//copy the temp. uploaded file to uploads folder
	$path_of_uploaded_file = $images . $name_of_uploaded_file;
	$tmp_path = $_FILES["uploaded_file"]["tmp_name"];

	if(is_uploaded_file($tmp_path))
{
  	if(!copy($tmp_path,$path_of_uploaded_file))
  {
    $errors .= '\n error while copying the uploaded file';
  }
}



	
    mail("min@e-mail.com", "Subject: $subject",
    $message, "From: $email" );
    echo "Thank you for using our mail form";
    }
  }
else
  {//if "email" is not filled out, display the form
  echo "<form method='post' action='formmail.php' ENCTYPE='multipart/form-data'>
  Email: <input name='email' type='text' /><br />
  Subject: <input name='subject' type='text' /><br />
  Message:<br />
  <textarea name='message' rows='15' cols='40'>
  </textarea><br />
  File to upload:<br>
  <INPUT TYPE='FILE' NAME='upfile'><br>
  <input type='submit' />
  </form>";
  }
?>

Jeg tror muligvis at det er fordi jeg ikke har defineret at den skal hente filen fra feltet som hedder "upfile" kan det passe?

og hvordan ville jeg kunne gøre det?

Tak
