<input type="text" value="<?php echo $sizes ?>" />

Answer 1

Your session is an array you have to loop it.
foreach ($_SESSION['sizes'] as $size)
{
echo $size;
}

Answer 2

But I want to post radio values how could I send?
Radio values from your form are sent automatically to the action specified when a user press the submit button. In the action page they can retrieve them via the $_POST or $_GET global array. In your case, since you are using the POST method, you can retrieve your radio box via:
$_POST['size'];
Actually I want to send when someone click on label then label values to another page.
Well, you can do that by make Javascript trigger an event when a radio box is selected and send a request via AJAX.
