    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');
    ?>

    I suggest doing this first without scripting, where you have an "Update Order" button that processes the ticked boxes and takes the appropriate action.
    That way you can guarantee that it works.

    Once the business logic is working, you can use scripting to hide the update button and perform a similar update, either by interacting via ajax with the PHP script or by directly updating the form.

    But first, get the business logic working without JavaScript. That's what I suggest in terms of this.
