vb.org Archive - multiple check boxes

I know how to work with regular forms. Even drop downs. But not when it comes to multiple selections.

In my case, I have 8 check boxes with the name "sizes[]" with different values. When a user checks 1 or more boxes, I want that information to pass on to the next page to get sent in an email. Here's the block of coding I'm using.

Code:

  <?php



$email = $_SESSION['MM_UserEmail'];

$username = $_SESSION['MM_Username'];

$userid = $_SESSION['MM_UserID'];

$instructions = $_POST['instructions'];



for ($x = 0; $x < count($sizes); $x++)

{

        $papersize = "$sizes[$x]";

}



$message = "$username (userid $userid) wants \"$paper paper\" and the following sizes:\n\n

$papersize

has sent the following instructions:\n\n\"$instructions\".";

$from = $email;

$to = "some@email.com";

$subject = "$username (userid $userid) Uploaded Photographs";

$headers = "From: $from";



mail($to,$subject,$message,$headers);

$paper is the name of a drop down form with different papers.
$sizes is the name of the 8 check boxes with different sizes.

Code:

for ($x = 0; $x < count($sizes); $x++)

{

        $papersize = "$sizes[$x]";

}

This peice of code is where I believe the problem lies. I tested it, and checked 3 sizes. However, only the last one is called out in the email. What am I doing wrong? I tried many ways, but no luck. Thanks for the help.

Andrew, I tried putting $papersize = "$sizes . $x"; but that didn't work. :p

I ran into this code which looked simpler but didn't work either.

Code:

   foreach($sizes as $value)

   {

      $papersize = "$value ";

   }
