code to retieve value whether POST or GET

[Microbe]

I am passing a value to a page. Some times it is a POST sometimes it is a GET.

I can do something like

	if(isset($_POST["key"])){
		$key= $_POST["key"];
	}
	elseif(isset($_GET["key"])){
		$key= $_GET["key"];
	}

but it seems a bit ugly and clumsy.

Is there a way to grab the value by just doing something like $_["key"] ?

hmmm...maybe I should try that...

Microbe,

The code in your first message is the preferred and more secured one. $_REQUEST superglobal variables cosists of variables passed via either GET, POST or COOKIE. So you will never be able to control if cookie is already set by this variable name.

I never set a goal because u never know whats going to happen tommorow.

Thanks for that.

In this case it isn't going to be a problem but will try to keep it in mind.

i'd prefer your first post. if you must use $_REQUEST, then understand about GPC order and that you might also be picking up a cookie value.

alternatively you could use this as a reusable function.

$key = extractVar('key');

function extractVar($varName, $order = 'PG'){
	if (strtoupper($order) === 'GP') 
		{$one = '_GET'; 	$two = '_POST'; } 
		else 
		{$one = '_POST'; 	$two = '_GET';}
	return isset(${$one][$varName]) ? ${$one}[$varName] : (isset(${$two}[$varName]) ? ${$two}[$varName] : '');
}
