Help With PHP + MySQL Thanks!

Here is the error:

[code]Notice: Undefined index: p in C:\xampp\htdocs\pages\leaderboard.php on line 5

Notice: Undefined index: sort in C:\xampp\htdocs\pages\leaderboard.php on line 6

Notice: Undefined index: mode in C:\xampp\htdocs\pages\leaderboard.php on line 7[/code]

Here is the code(obviously only some):
[php]<?php
//require_once( ‘…/db_con.php’ );

$per_page = 50;
$p = mysql_real_escape_string(addslashes($_GET[‘p’]));
$sort = mysql_real_escape_string(addslashes($_GET[‘sort’]));
$mode = $_GET[‘mode’];
if(trim($sort) == “”)
$sort = ‘total_points’;
if($mode == “raw”){
$per_page = 1000000000000000;
}[/php]

I dont know whats wrong?

[aztech4mac]

how are you calling this file?

It should be something like;

myscript.php?p=data1&sort=data2&mode=data3

p, sort, mode can be in any order.

You also can’t use mysql_real_escape string unless a mysql database connection is open or it returns errors.
