POST input

[gonny]

Hi all!

I want to show some content if is any $_POST[''] input.
Ex. index.php?show=page where $_POST is $_POST['show'] and I have many $_POST.
Now I want a case like:
if (!$_POST['*']) { $content="bla bla"; }

What can use * or '' blank into POST to mean there is any input?

Hi gonny,

I think you are getting comfused with your superglobals. $_POST is for POST data. In your example, 'show' is $_GET data.

if (!isset($_GET['show'])) { $content="bla bla"; }
if (isset($_GET['show']) && $_GET['show']!='page') { $content="bla bla"; }

etc etc

Thnx for replying me dreamcatcher: What I want is if exist a way to identify any $_GET or $_POST. $_GET['show'] identify "show" case only.

Rather than use a wild card character
if (!$_POST['*']) { $content="bla bla"; }

just test for the existence of the $_POST array:

if(isset($_POST) will return true if ANY $_POST variables is set

Similarly,
if(isset($_GET) )will return true if ANY $_GET variable is set.

Actually you should check that the arrays are empty, as they are set anyway by default.

if (!empty($_POST)) {
}
if (!empty($_GET)) {
}

if i get it right yo are asking something like:

$content = "";
foreach ($_POST as $key=>$value)
{
$content .= $key." = ".$value."<br>";
}
echo $content;

I hope i understand correctly what you are asking gonny
