lanceox · March 30, 2011

hi guys, the problem is, is that all of the code works fine, however im trying to post the user to the leader board (leaders.xml) however it just isnt adding to the xml page and im not too sure why.

I attached all 3 files that you may need to see to figure it out. Hope you can really help, I would really appreciate it.

Okay this section is the index where the user enters their user name

<?php
session_name("elearning_Test");
session_start();
$_SESSION['score'] = 0;
$_SESSION['correct'] = array(); 
$_SESSION['wrong'] = array();
$_SESSION['finished'] = 'no'; 
$_SESSION['num'] = 0;
require_once ('functions.php');
?>

And finally this section is the functions page.


<?php

// shuffle answers
function shuffle_assoc($array) {

  $keys = array_keys($array);
  shuffle($keys);
  $shuffled = array();
  foreach ($keys as $key)
    $shuffled[$key] = $array[$key];

  return $shuffled;
} 
  
  
// leader board section
function showLeaders($file,$limit,$group = null) { 
$leaders = array();

// Load the xml file and place all users and associated 
	// scores into the 'leaders' array.
	$xml = simplexml_load_file($file);
	foreach($xml->user as $user) 
{
		$name = (string)$user->name;
		$score = (string)$user->score;
		$leaders[$name] = $score;
	}

	// Sort the leaders array numerically, highest scorers first.	
	arsort($leaders,SORT_NUMERIC);

	// Initialise our $counter variable to '1'.
	$counter = 1;

	// Start a html ordered list to hold the leaders.
	$output = "<ul class=\"leaders\">\n";

	// Loop through the 'leaders' array and wrap each username and score
	// in <li> tags. If the user is the current $_SESSION['user'], wrap
	// the name/score in <strong> tags too.
	foreach ($leaders as $key => $value) 
{
		// Check that $counter is less than $limit.
		if ($counter <= $limit)
	{
			if ($key == $_SESSION['user'])
		{
				$output .= "<li><strong>$key:</strong> $value/20</li>\n";
			}
		else 
		{
				$output .= "<li>$key: $value/20</li>\n";
			}
			// Check to see if $group parameter has been passed.
			// If it has, create separate lists according to the $group variable.
			if ($group) 
		{
				// Use the modulus operator(%) to create new sub-list.
				if($counter % $group == 0) 
			{
					$output .= "</ul>\n<ul class=\"leaders\">\n";
				}
			}
		}
	// Increment the $counter.	
	$counter++;
	}
	// End the ordered list.
	$output .= "</ul>\n";

	// Print out the ordered list.
echo $output;
}

function showAnswers($answers,$questions) { 
for($x = 0; $x< count($answers); $x++) {
	if ($x % 2 == 0) { 
	 	$output = "<div class=\"qanda clear\">\n";
	} else { 
		$output = "<div class=\"qanda\">";
  		}
	$output .= '<h4>Question' . ($x+1) . ': ' . $questions[$x] . '</h4>'; 
$output .= "<ol>\n";
	for ($y = 0;$y< count($answers[$x]); $y++) {
		if (($answers[$x][$y] === $answers[$x][0]) && (in_array($answers[$x][$y],$_SESSION['correct']))) {
			$output .= "<li class=\"correctuser\">{$answers[$x][$y]} (Correct!)</li>\n";
		} else if ($answers[$x][$y] === $answers[$x][0]) {
			$output .= "<li class=\"correct\">{$answers[$x][$y]}</li>\n";
		} else if (in_array($answers[$x][$y],$_SESSION['wrong'])) {
			$output .= "<li class=\"wrong\">{$answers[$x][$y]} (Woops!)</li>\n";
		} else { 
			$output .= "<li>{$answers[$x][$y]}</li>\n";
	}
}
$output .= "</ol></div>\n";
echo $output;
}
}
?>
