PHP Warning: Undefined index:

[squealer]

I've the following error:
"PHP Warning: Undefined index:"

I know it's because i requested a field that i didn't send, i use this page sometimes with $doit and sometimes without $doit in the submited form, so how can i fix the warning?

$doit = $_REQUEST["doit"];

You can check if $doit is set, something like this:

if (isset($doit)) {$doit = $_REQUEST["doit"]; }

Or you can hide the error anyway with

$doit = @$_REQUEST["doit"];

Personally I'd use both, as you don't want the error, but hide it in case you do get it :-)
