Occasions within the Shared\Controller classification namespace Shared { use Framework\Events as occasions; use Framework\Router as Router; use Framework\Registry as Registry; type Controller extends \Framework\Controller { public functionality setUser($user) { $session = Registry::get("session"); if ($user) { $session->set("user", $user->id); } else { $session->erase("user"); } $this->_user = $user; go back $this; } public functionality __construct($options = array()) { parent::__construct($options); // connect with database $database = Registry::get("database"); $database->connect(); // agenda: load person from consultation Events::add("framework. router. beforehooks. before", function($name, $parameters) { $session = Registry::get("session"); $controller = Registry::get("controller"); $user = $session->get("user"); if ($user) { $controller->user = \User::first(array( "id = ? " => $user )); } }); // time table: shop person to consultation Events::add("framework. router. afterhooks. after", function($name, $parameters) { $session = Registry::get("session"); $controller = Registry::get("controller"); if ($controller->user) { $session->set("user", $controller->user->id); } }); // agenda: disconnect from database Events::add("framework. controller. destruct. after", function($name) { $database = Registry::get("database"); $database->disconnect(); }); } } What we’ve performed is upload new occasion listeners to the __construct() approach to the Shared\Controller category. those hook the person session–related information into the request cycle. the 1st occasion, which retrieves a person row in keeping with consultation facts, occurs while the development "framework. router. beforehooks. prior to" fires. which means it's going to happen prior to any motion hooks or activities are finished. the second one occasion, which shops a consumer connection with the consultation, occurs while the development "framework. router. afterhooks. after" fires. which means it's going to take place finally the motion hooks and activities are performed. We’ve additionally overridden the $_user setter approach. this is often in order that the login() and logout() activities could make speedy adjustments to the consultation. The store occasion is the same to the code we have been repeating within the login() and settings() activities, in up to it takes the person row and saves it to the consultation. We get this information from the controller’s person estate, which for this reason is the user’s identification. this can be far better than our prior strategy since it permits us to deal simply with the controller’s consumer estate, and we not have to even take into consideration saving consumer rows to consultation! we're additionally now not saving all of the user’s info to the consultation, yet fairly simply the user’s identification estate. this implies we additionally have to request the consumer row after we pull the reference from the consultation, yet this is often leading to storing every little thing within the consultation. lets additionally shop the consumer row in cache, to avoid wasting the overhead of an extra database question, yet that’s now not very important immediately. Now we have to deal with that Hypertext Preprocessor computer virus.
