response - How to set status code from service layer in Symfony 2? -

-

i have service helping me validate forms. want set http status code inside of when finds form invalid.

is ok so? how do it? thanks!

the way (probably there's lot more solutions) throwing (custom) exception in service in case form invalid.

then create exception listener listen on kernel exception event. configuration of such listener (services.yml)

kernel.listener.your_listener:     class: acme\your\namespace\yourexceptionlistener     tags:         - { name: kernel.event_listener, event: kernel.exception, method: onexception }

and onexception method in yourexceptionlistener class:

public function onexception(getresponseforexceptionevent $event) {     $exception = $event->getexception();     if ($exception instanceof yourcustomexceptioninterface) {         $response = new response('', 400);         $event->setresponse($response);     } }

this way nicely decoupled stuff, , form validation service independent of response.

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
