That's correct behavior. As you're simply running action.php on its own,
it sees that $_POST['name'] and $_POST['age'] don't exist and outputs a
notice for each.

To avoid the notices, ensure that those keys exist before calling
something like echo on them:

<?php

if (!empty($_POST['name'])) {
	echo $_POST['name'];
} else {
	echo 'Name not set';
}

if (!empty($_POST['age'])) {
	echo $_POST['age'];
} else {
	echo 'Age not set';
}

?>

HTH!
