When I try the code below I get:
“Undefined index: dye in /opt/bitnami/apps/wordpress/htdocs/wp-content/plugins/code-snippets/php/snippet-ops.php(352) : eval()’d code on line 2″

<form action=”” method=”post”>
<input checked=”checked” name=”dye” type=”radio” value=”0″ /> Dye 1
<input name=”dye” type=”radio” value=”1″ />Dye 2
</form>

add_action( ‘template_redirect’, function () {
$dye = $_POST[‘dye’];
print_r($dye);
} );
