Echo your query before inserting, I am sure it is invalid.

First of all, you have too many if(isset($_POST['save'])) conditions. Second, how did you store multiple id's in the form? Thirdly... what is this? "foreach($_POST as $data =>$d)"? By the way... no filtering?

for($i=0;$i<$num_entry;$i++)
                    {
                    if($i!=$num_entry)
                        {
                        $insert.="$d,";
                        }
                    else
                        {
                        // will never run because for-loop exits at same value
                        $result=mysql_query($insert)or die(mysql_error());
                        }
                    }
           // $insert still not finist here see:
           echo "<br/>$insert<br/>";
