score keeps incrementing? cant see why though

lanceox · March 26, 2011

hey guys. Hopefully someone can help me with this. I have been trying to figure out for a while now why the quiz score keeps incrementing even if i refresh the page.

so far there is 2 quiz sections, firstly $_SESSION['score']; is incremented on every correct answer then this information is carried on to the second part of the quiz which increments $_SESSION['score'1];

However everytime a page is refreshed then it increments again. How can i get around this?

Also note i have a questions and answers section (array of q's and a's) and a functions page. Any help would be great.

Thanks in advance

Lance

<?php
session_name("Question_Test");
session_start();
$_SESSION['score'];
require_once('questionsandanswers2.php');
require_once('functions.php');


if (!isset($_POST['submit'])) 
{	
	$score1 = 0;
	$_SESSION['correct'] = array(); 
	$_SESSION['wrong'] = array();
	$_SESSION['finished'] = 'no';

	if (isset($_SESSION['error']))
	{
		unset($_SESSION['error']); 
		$num = 0;
	} 
		else
	{
	$score1 = 0;
	$_SESSION['score1'] = $score1;
	$_SESSION['correct'] = array(); 
	$_SESSION['wrong'] = array(); 
	$_SESSION['finished'] = 'no';
	$num = 0;
	} 
}
else
{
$num = (int) $_POST['num'];
$postedanswers = str_replace("_"," ",$_POST['answers']);
	if ($postedanswers == $answers[$num]['0'])
	{
		$_SESSION['score1'] ++;
		$_SESSION['correct'][] = $postedanswers; 
	} 
	else
	{
		$_SESSION['wrong'][] = $postedanswers;
	}	

if ($num < count($questions)-1) 
{
	$num++;
} 
	else 
{
	$last = true;
	$_SESSION['finished'] = 'yes';
}
}
