在给出排名时添加积分

Question

是的，所以我有一个促销按钮设置。有人收到的每个促销活动都会给他们提供积分，但每个等级都有不同的分数，具体取决于它的高低或高低。我很难弄清楚如何通过他们的排名来获得积分。我的数据库列称为：rank和rank在数据库中称为数字，当它在外部显示时，它们都具有函数的名称。所以即;等级1,2,3,4等于Noob，会员，精英，上帝。无论如何，如果你能帮助我找出我的错误，那将是伟大的，有点新的PHP。我遇到的问题是没有给予该人这些要点。他们得到提升，但没有分数。

promote.php

    <?php include_once('../classes/check.class.php'); ?>
<?php  include('../config/db.php'); ?>
<?php include('functionsprom.php'); ?>
<?php if( protectThis("1, 2, 3") ) : ?>
<?php

 if (isset($_GET['id']) && is_numeric($_GET['id']))
 {
 $id = $_GET['id'];
 $date = date('d M y');
 $prom = promote;
 $result = mysql_query("UPDATE players SET date='$date', rank = rank + 1, exp = exp + '$prom' WHERE id=$id", $db1)
 or die(mysql_error()); 

    require_once("../config/logdb.php");
 include('../logs.php');
 write_mysql_log($promote, $db);


 header("Location: ../home.php");
 }
 else
 {
 header("Location: home.php");
 }

?>
    <?php endif; ?> 

functionsprom.php

    <?php
include('functionsrank.php');
mysql_select_db('pts_player');

$rank = "SELECT rank FROM players WHERE id = $id";

    function promote($rank) {
    if($rank == 1):
    $prom = 0;

    $prom = 0;
