Laravel Pass Parameter from Route to Filter


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"?


Solution

  • 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";
    });
