PHP Error : Undefined Index

Question

This is going to sound really stupid, but I cannot figure out why I am getting this error.

Notice: Undefined index: o in C:\inetpub\wwwroot\webres\OC_defaults.php

    $o = !empty($o) ? $o : $_REQUEST['o'];
    $ST_defaults["office"] = !empty($o) ? strtoupper($o) : $officeDefault;
    extract($ST_defaults);

Thanks, Jatin

Are you expecting o to be passed to your page via the query string? — Fabien Warniez

$_REQUEST['o'] is not set. .. a simple fix would be to add

if(!array_key_exists('o',$_REQUEST)){$_REQUEST['o']='';};

oh, also, don't use $_REQUEST, its bad practice, its lazy, where the data comes is unknown, corruption/overwriting is possible~

use $_COOKIE / $_POST / $_GET instead..

o is not defined in the associative array $_REQUEST.

You can check if it is defined by using isset($_REQUEST['o']).

Hi Fabien, I did isset() and it does not show that error now. But where does it show the checked value.

Fabien Warniez Over a year ago

isset checks if the value is set. If it returns false, the value is not set. Now your problem is that that value is not set, you need to figure out why not. How is 'o' supposed to be passed to your page? GET or POST?
