variable scope

[otha]

In the following function all of the variables except $topOpen are assigned values in a form (method=post),
the $offsetf is the name of a set of radio buttons, with top being one of the values.
$desireda is also given a value in the form on a html document.
<?
function desfaceError(){
$topOpen= ($offsetf== top);
if($topOpen)
{$desireda = $desireda;}
else
{$desireda = -$desireda;}
;
return $desireda; }
?>
is the scope of the variables my problem, or am I asking for the wrong return value? If the scope is the problem how do I declare the variables global? or is that the right way to be heading?

You need to use the $_POST global. eg;

[code=php:0]
$_POST['offsetf']
[/code]

[printf]

Change local names to thier SUPER GLOBAL names!

Instead of....

[code]$offsetf[/code]

Use...

[code]$_POST['offsetf'][/code]


$_POST, $_GET, $_REQUEST, $_SERVER, $_FILES, $_SESSIONS, $_ENV, $_COOKIE, $GLOBALS

All have global scope!

me!
