    you have used if($delete){ but u didnt assigned any value for $delete and in your case i think it wont accept if you give $delete = $_POST['delete'] since delete is the submit button so you to have give a hidden field like <input type="hidden" name="chk_del" value="1"> infront of the delete (submit)button and instead of checking if($delete) u have to check if(isset($_POST['chk_del'])) it will work well then hope so...since i'm in rush i cant execute the code...u test execute if any issues araise u post here...

    1. Before this line

    "// Check if delete button active, start this"

    add the code below

    $delete = null;
    $checkbox = array();

    if(isset($_POST['delete']))
    {
    $delete = $_POST['delete'];
    $checkbox = $_POST['checkbox'];
    }

    2. find the lines below:

    $del_id = $checkbox[$i];
    $sql = "DELETE FROM $tbl_name WHERE id='$del_id'";
    $objQuery = mysql_query($sql);


    and replace with lines below

    $del_id = $checkbox[$i];
    if($del_id > 0)
    {
    $sql = "DELETE FROM $tbl_name WHERE id='$del_id'";
    $objQuery = mysql_query($sql);
    }

    Enjoy!
