If you're used to running on a system with register_globals turned ON then you might run into a snag with something like this since the GET and POST values aren't automatically assigned to the variables you're trying to echo.
You need to do:
$variablename = $_GET["variablename"];
Or...
$variablename = $_POST["variablename"];
Or..
$variablename = $_REQUEST["variablename"];
The last one (REQUEST) will populate the $variablename variable with either GET or POST data so can be used for either. I forget the order that it takes it though, I believe it essentially does:
If (isset($_POST["variablename"])) $variablename = $_POST["variablename"];
If (isset($_GET["variablename"])) $variablename = $_GET["variablename"];
(or vice versa)
So if both $_POST["variablename"] and $_GET["variablename"] are both set, then the data stored in the GET overwrites the POST data previously assigned to $variablename.
It IS possible to pass both POST and GET data at the same time:
<form action="index.php?GETVARIABLE=testget" method="POST">
<input type="text" name="POSTVARIABLE" value="testpost">
</form>
Var_dump($_REQUEST) will have both GETVARIABLE and POSTVARIABLE values ("testget" and "testpost" respectively) available where as $_GET only has the GETVARIABLE value ("testget") and $_POST only has the POSTVARIABLE value ("testpost")
