The snippet itself is not interactive, it is executed as a piece of raw PHP code. So the simplest implementation would be something like this:

switch ($action) {
    case 'firstAction' :
        $class->firstMethod();
        break;
    case 'secondAction' :
        $class->secondMethod();
        break;
}

And then, at the right place in the template, the snippet with the passed parameter is called: Or Fenom:

{'!yourSnippet' | snippet : ['action' => 'firstAction']}
