[SOLVED] Stopping page refreshing

[darkfreaks]

page refreshing. okay i have a PHP  game that mainly uses javascript to validate everything then switches to PHP to insert the user's score into the database and award points , however there have been complaint's of "cheating" because you can refresh the page over and over and get those points even if it starts a new game. ok here is the code.

 

 

 <?php

$button =  "<input type='submit' name='submit_Score' value='Submit Score!!'>";

if($_POST['submit_Score']){



$score = trim(strip_tags($_POST['show']));
$gameScore = $score / 4;
$gameScoreFinal = round($gameScore);
points("$game", "$username", "$gameScoreFinal");

$button="You have recieved <b>" . $gameScoreFinal. "</b> CP's. They have been added to your account.<br><br><center>

Why not set session data....if the score has been submitted set a session string then check that on page load.

[darkfreaks]

i think i got it, the problem seems to be $_POST['show'], it seems like it needs to be set in a session to avoid refreshing. thanks

More like:

 

<?php 
session_start();

if (isset($_SESSION['submit_score'])) 
    die("You have already submitted.");

$_SESSION['submit_score'] = $_POST['submit_score'];

?>

 

That would work, but you may want to put the actual setting of the session in a spot past any probably errors that may occur...
