Get the subdomain in a subdomain-route (Laravel)

Question

I'm building an application where a subdomain points to a user. How can I get the subdomain-part of the address elsewhere than in a route?

Route::group(array('domain' => '{subdomain}.project.dev'), function() {

    Route::get('foo', function($subdomain) {
        // Here I can access $subdomain
    });

    // How can I get $subdomain here?

});

I've built a messy work-around, though:

Route::bind('subdomain', function($subdomain) {

    // Use IoC to store the variable for use anywhere
    App::bindIf('subdomain', function($app) use($subdomain) {
        return $subdomain;
    });

    // We are technically replacing the subdomain-variable
    // However, we don't need to change it
    return $subdomain;

});

The reason I want to use the variable outside a route is to establish a database-connection based on that variable.

Answer 1

Shortly after this question was asked, Laravel implemented a new method for getting the subdomain inside the routing code. It can be used like this:

Route::group(array('domain' => '{subdomain}.project.dev'), function() {

    Route::get('foo', function($subdomain) {
        // Here I can access $subdomain
    });

    $subdomain = Route::input('subdomain');

});

See "Accessing A Route Parameter Value" in the docs.

Way with macro:

Request::macro('subdomain', function () {
    return current(explode('.', $this->getHost()));
});

Now you can use it:

$request->subdomain();
