savegenarateBarcode.php:

<?php

try{
session_start();
include('../connect.php');



$d1=$_GET['id'];
$b=$_POST['serialnumber'];

$query = $db->prepare($sqlm);
$user_array = $query ->execute();

Answer

I think you should use ajax because the form submit method reload the page.

var id = '<?php echo $d1; ?>';
$("#submit").click(function(){
        $.ajax({
            type: 'GET',
            url: "savegenarateBarcode.php",
            data:`id=${id}`
            success:function(data){
             alert(data);
            }
        });
    return false;
    });
