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 Code:
<?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'], 06);
            
$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'], 06);
            
$currentYMD date("ymd");
            if (
$currentYMD $currentSRYMD
            {  
                
$currentSRNum 1;
            } 
            else 
            {  
                
$currentSRNum += 1;
            }                                           
        }
//------------------------------------------------------------------------------------------------------------------         
        
$yearMonth date('ymd');    
        
$currentSR $currentYMD sprintf("%04d"$currentSRNum);  
?>
