php - Slim Route Group not passing url variable to the callback -

i trying use slim's route groups, having trouble getting url parameters pass in.

$app->group('/contest/:id', function($id) use ($api){     error_log('this contest id: '.$id); // id blank... why?     $api->authorize('contest', $id);     $contest = new contest($id);      $app->get('', function() use ($contest, $api){         $data = $contest->getsettings();         $api->output($data);     });      $app->get('/settings', function() use ($contest, $api){         $data = $contest->getsettings();         $api->output($data);     });      $app->get('/stats', function() use ($contest, $api){         $data = $contest->getstats();         $api->output($data);     });      $app->get('/fields', function() use ($contest, $api){         $data = $contest->getfields();         $api->output($data);     }); }); 

why can't access $id in callback function? isn't point of route groups?

i've tried reproduce - last stable release 2.6.2 - , got (probably) same problem you.

warning: missing argument 1 {closure}()

route params in group placed in callback childs:

$app->group('/contest/:id', function() use ($api){      $app->get('', function($id) use ($contest, $api){         $api->authorize('contest', $id);         $contest = new contest($id);         $data = $contest->getsettings();         $api->output($data);     }); }); 

but yeah it's ugly authorize in every single route, maybe in kind of middleware? think last 1 on docs page looks needs.

edit
