Laravel Pass Parameter from Route to Filter

Question

I am using the laravel framework. If I have the following route:

Route::get('/test/{param}', array('before'=>'test_filter', 'SomeController@anyAction'));

And this filter:

Route::filter('test_filter', function() {
    $param = [Get the parameter from the url];
    return "The value is $param";
});

How can I pass parameters to the filter so that when visiting /test/foobar I would get a page saying: "The value is foobar"?

Answer 1

Filters can be passed parameters, like the Route object or the Request:

Specifying Filter Parameters

Route::filter('age', function($route, $request, $value)
{
    //
});

Above example is taken from the docs: http://laravel.com/docs/routing#route-filters

Once you're inside the closure, you take the parameter from the $route:

Route::filter('test_filter', function($route) {
    $param = $route->getParameter('param'); // use the key you defined
    return "The value is $param";
});

Alternatively, I believe you can just fetch the segment you need (not tested but should work):

Route::filter('test_filter', function() {
    $param = Request::segment(1);
    return "The value is $param";
});
