[sde]

i want to start coding, or at least know how to be complian with notices. i have all errors reporting including notices.

please advise me how to adjust the code below to not get a notice.

PHP Code:

<?php
if($_GET['player_id'])
{
  $player->setPlayer($_GET['player_id']);
}
?>

error

Notice: Undefined index: player_id in /www/player.php on line 2

well id suspect you have to grab that section of the query string yourself ... ie split it up based on "&'s, and "="'s.. should be trivial with the regexps ...
