I have designed a small web-based system that have a school evaluation form to ask specific users who can access the system" some questions and the input will be a radio type ( 1 or 2 or 3 or 4)!
the code is working and can inserts the input
into the database but i don't know the correct query to calculate the total mark and store it in the database, this is currently working code below:
<?php
session_start();
$Load=$_SESSION['login_user'];
include('../connect.php');
$sql= "Select name from student where ID='$Load'";
$username = mysql_query($sql);
$id=$_SESSION['login_user'];
if (isset($_POST['submit']))
{
$v1 = $_POST['v1'];
$v2 = $_POST['v2'];
$v3 = $_POST['v3'];
$total = $_POST['total'];
mysql_query("INSERT
into Form1 (P1,P2,P3,TOTAL)
values('$v1','$v2','$v3','$total')") or die(mysql_error());
header("Location: mark.php");
}
?>
<html>
<head>
<?php
if(!isset($_SESSION['login_user']))
header("Location:index.
html");
?>
