I have a simple system for a University Project which I have become stuck with an would really appreciate some help. I have created a 5 star rating system based on the user logged on, my project will all be running on localhost, but i need multiple people to test it on the same device.
My rating system works fine and inserts into my database with the ratings, however I wish to use my rating system across multiple pages. I have two files to complete my this action E1index.php and E1ajax.php which I have included.
I tried creating separate index files for my other pages (E2index.php, E3index.php etc ) so that the same user can rate multiple pages, but only 1 rate per user is inserting into my database, the second rate will overwrite the first.
My question is, can anyone explain how I can amend my code to have my rating insert into a separate row for the same user depending on the page they are on?
E1index.php
<?php
session_start();
include_once 'dbconnect.php';
if( !isset( $_SESSION['user'] ) ) header("Location: index.php");
$res=mysql_query("SELECT * FROM users WHERE user_id=".$_SESSION['user']);
$userRow=mysql_fetch_array( $res );
$post_id = '1';
?>
