Undefined index: $_GET and !isset

[new_born191285]

Hi all,

I have 2 undefined index errors which I don't know hot to solve (I am new to PHP) :quiet: I would appreciate it if anyone can help solve these 2 errors;

 

[Notice: Undefined index: mode in /var/www/html/phpTrafficA-2.0.1/index.php on line 54

 

Notice: Undefined index: mode in /var/www/html/phpTrafficA-2.0.1/index.php on line 56

 

<?php
if (!isset($mode) or $mode == "") {
$mode = 
$_GET["mode"];
if ($mode == "") { $mode = 
$_POST["mode"];}
?>

 

I'm running php 5.2.6 and have register_globals on if that helps

 

Cheers,

Turn register_globals off, it is deprecated and will be removed in php6. About the problem, 'Undefined index' means that 'mode' isn't an array index. That means that you haven't a get variable and/or a post variable called 'mode'.

Use something like:

<?php
if (isset($_GET['mode'])) $mode = $_GET['mode'];
if (!isset($mode) && isset($_POST['mode'])) $mode = $_POST['mode'];
if (!isset($mode)) $mode = 'Error';
?>

 

And TURN OFF REGISTER GLOBALS (Yes, I'm shouting)
