[symfony-users] Get number of values in a filter form

[Michael Smith]

I want to customize the admin generator template with the number of
filters that are currently applied if any. Is there a way to get this
easily from the generated filter form? The code below works but I was
wondering if there was a better way.

$cx = 0;
foreach($form->getDefaults() as $default){
        if(is_array($default)){
                foreach($default as $value){
                        if($value != ''){
                                $cx++;
                                break;
                        }
                }
        }else{
                if($default != ''){
                        $cx++;
                }
        }
}

Thanks,
Michael
