hi all i have this project to do b ut i have having a bit of a problem with checkbox, only selected checkbox goes to the database. it works but only the first value which is chips is inserted even if chapati is selected.
below is the html code:

<?php session_start();
include("conn.php");
    if(isset($_SESSION['id'])){
        $query="SELECT name, course FROM details where id like '".$_SESSION['id']."'";
        $result_user=mysql_query($query,$conn);
        $id=$_SESSION['id'];
        $name=mysql_result($result_user,0,0);
        $course=mysql_result($result_user,0,1);
 ?>

From skimming over your rather long code, it looks like you aren't setting any values for the checkboxes.

Have a look at this recent tutorial that has some good information about checkboxes.
