input data to the textbox after read the barcode using barcode scanner

Hi..

I just want to know how does it happen that when I scan the barcode using barcode scanner it will automatically put on the first textbox, then the focus will go to the next textbox and on the last textbox will automatically save the data to database.

here is my sample form.

<?php                                                                          
   error_reporting(0);
   date_default_timezone_set("Asia/Singapore"); //set the time zone  
$con = mysql_connect('localhost', 'root','');

if (!$con) {
    echo 'failed';
    die();
}

mysql_select_db("mes", $con);
$sr_date =date('Y-m-d H:i:s');

$sql = "SELECT sr_number FROM receiving_materials ORDER BY sr_date DESC LIMIT 1";
        $result = mysql_query($sql, $con);
        
        if (!$result) {
            echo 'failed'; 
            die();
        }
        $total = mysql_num_rows($result);
        if ($total <= 0) {
            $currentSRNum = 1;
             $currentYear  = (int)(date('y'));
            $currentMonth = (int)(date('m'));
            $currentDay = (int)(date('d'));
           
            $currentSRYMD = substr($row['sr_number'], 0, 6);
            $currentYMD = date("ymd");
            if ($currentYMD > $currentSRYMD) 
            {  
                $currentSRNum = 1;
            } 
            else 
            {  
                $currentSRNum += 1;
            }     
             
        } 
        else {
//------------------------------------------------------------------------------------------------------------------
            // Stock Number iteration.... 
            $row = mysql_fetch_assoc($result);
            
            $currentSRNum = (int)(substr($row['sr_number'],0,3));
            
            $currentSRYear  = (int)(substr($row['sr_number'],2,2));
            $currentSRMonth = (int)(substr($row['sr_number'],0,2));
            $currentSRNum = (int)(substr($row['sr_number'],6,4));

            $currentYear  = (int)(date('y'));
            $currentMonth = (int)(date('m'));
            $currentDay = (int)(date('d'));
           
            $currentSRYMD = substr($row['sr_number'], 0, 6);
            $currentYMD = date("ymd");
            if ($currentYMD > $currentSRYMD) 
            {  
                $currentSRNum = 1;
            } 
            else 
            {  
                $currentSRNum += 1;
            }                                           
        }
//------------------------------------------------------------------------------------------------------------------         
        $yearMonth = date('ymd');    
        $currentSR = $currentYMD . sprintf("%04d", $currentSRNum);
