Notice Undefined index: reset/ Attempting to redirect, works, but get a notice

Posted on 16th Feb 2014 by admin

Full Header.php is:
Code: [Select]<?php
$reset= false;
$reset= strip_tags($_GET["reset"]); //THIS IS LINE 3
if(empty($reset))
$reset = false;
if($reset==NULL)
$reset=false;
if($reset==true){
session_destroy();
header( 'Location: index.php' ) ;
}
?>

and i get the "Notice":
Undefined index: reset in /Users/../header.php on line 3

What is going on? If you need more information, here is start and end of my main file, index.php
Code: [Select]<?php
ini_set('display_errors',1);
error_reporting(E_ALL|E_STRICT);

session_start();
require_once("includes/header.php");
require_once("includes/constants.php");

//...
?>
<a href="index.php?reset=true">CLICK HERE TO RESET AND DESTROY ALL DATA</a>

So i only get this error when i go to index.php
index.php?reset=true works for me, but the problem is later after it redirects me back to index.php, the "Notice" is displayed..
How do i fix this??
