Hi,
There are multiple Ways of getting that string.
If your PHP-Server has globals=on in php ini you will recive that string in
$selection variable.

If not you recive it in $_GET["selection"]

So I use a function to handle POST and GET Variabels.

function getpost_ifset($test_vars)
{
$return = FALSE;
if (!is_array($test_vars))
{$test_vars = array($test_vars);}

foreach($test_vars as $test_var) {
if (isset($_POST[$test_var])) {
global $$test_var;
$$test_var = $_POST[$test_var];
$return =
TRUE;
} elseif (isset($_GET[$test_var])) {
global $$test_var;
$$test_var = $_GET[$test_var];
$return =
TRUE;
}
}
return $return;
}

If i now want to get a ariable i either POST or GET from an URL i don't care
if POST or GET.
I just do

getpost_ifset("selection");

and then I have a variable called $selection in my code with the given
value.

You could also do something like this.

if(getpos_ifset("selection"))
{
echo "Selection variable is there with value: ".$selection;
}
else
{
echo "No Selection Variable givin in Link";
}

Hope that helps.
