The Scoring module

First, we will take a look at the Scoring module. It consists of JavaScript with an Ajax call to actually get the score data from the database. Here is the code for the JavaScript method:

function GetMyScore(){
  var action='GetMyPoints',
    player=getFromLocalStorage('player');
   $("#myscore").html('0');
   $.ajax({
        dataType: "text",
        data: {action:action,player:player},
        url: $AJAXHANDLER,
        success: function (data) {
    $("#myscore").html(data);
  },
        error: function (xhr, status, error) {
            alert(status + error + xhr.responseText);
        }
    });
  
  }

AjaxHandler.php

In the following code, the Ajax method calls ajax_handler.php, whose job is to accept the Ajax call and call the correct PHP function based on the action parameter passed to it by the Ajax call:

<?php include 'vupoint.php'; ?>
<?php
if(isset($_GET['player'])){$player=$_GET['player'];  }

switch ($_GET['action']) {
  case 'GetMyPoints':
  GetMyVuPoints...
