Help with Controllers
Hi.
I don't understand, how true make controllers in MVC model.
My current realization (reduced):
PHP Code:
// User Controller - delete, save and edit user data
// Each method performs certain actions and generates a variable to "View",
// which are used in the templates of specific pages.
class User_Controller
{
// main method.
// this method execute all others methods of this controller
public function run($method)
{
// if in request exists key id_user,
// get user data from user_mapper class
if ($id = $this->request->get('id_user', 'int'))
{
$this->user = $user_mapper->findById($id);
}
$this->$method();
}
// edit and add user in database
public function edit()
{
// if POST method (save or edit user data)
if (POST)
{
$this->user = $user_mapper->createObjectByArray($this->request->getData('post'));
// check errors ....
$errors;
if (!$errors)
{
$user_mapper->save($this->user);
header('Location: ....');
exit;
}
// set view error data as array-vars
$this->view->errors = $errors;
}
// set view user data as array-vars
$this->view->user = $this->user->getDataAsArray();
}
// view user data
public function view()
{
$this->view->user = $this->user->getDataAsArray();
// important! here other vars go to "View"-component
$this->view->other_vars = $this->other_method(); // this method run mysql or other operations with systems resourse
}
// delete user from database
public function delete()
{
$user_mapper->delete($this->user);
}
// and etc...
}
Front Controller activate this class:
PHP Code:
$c = new User_Controller();
$c->run($method_name);
Problem.
In method User_Controller::view() we are see this code:
PHP Code:
// important! here other vars go to "View"-component
$this->view->other_vars = $this->other_method(); // this method run mysql or other operations with systems resourse
this code make operations, specific for page /user/view/id125.html
If i have use class and method User_Controller::view() in other Controller, then I have to running and code
PHP Code:
// important! here other vars go to "View"-component
$this->view->other_vars = $this->other_method(); // this method run mysql or other operations with systems resourse
but this code is run I do not need.
I don `t know, how to make *!* |
