Optional section in URL

[bossqone]

Hello, how can I make "lang" section optional, please ?

There is regexp - "/\w{2}:lang/pages/:title"

Thanks for quick answer. (Sorry for my bad english).

You can't really make a part optional at this point, you'd have to define two separate routes for this:

$r->add('/\w{2}:lang/pages/:title', ...);
$r->add('/pages/:title', ...);

If you have to do this a lot, you could automate the creation of these routes:

foreach ($myRoutes as $route) {
    $r->add('/\w{2}:lang' . $route['route'], ...);
    $r->add($route['route'], ...);
}
