    need help in checkboxes inside while loop

    Hi,

    I created picking module and now I need help in subtract/minus Demanded Qty to the Qty from the wms table based on the lot number selected and it will happen only when the checkbox was check.

    Here is the flow:

    1. Select SR #
    2. After Select SR # data will display below
    3. Choose Lot Number
    4. Check the beside textbox to subtract/minus the demanded qty to the lot number qty from wms table
    5. When the check box was check and after subtract the select option will be only display the lot number you selected.

    I am new in using checkbox.

    Here is my code:

    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);
    $Date_Shelve =date('Y-m-d H:i:s');
    ?>
