Scusa, ma a me sinceramente rivedere per l'ennesima volta la ricreazione di un framework da 0 stomaca alquanto. Partendo dal presupposto che l'MVC è un pattern abbastanza semplice da capire, la sua implementazione fatta come si deve richiede parecchio lavoro. Soprattutto quando parli di "M", li le cose si complicano alquanto.
Capisco perfettamente, ma il mio intento era di iniziare a capire mvc da un piccolo progetto.
A questo punto mi viene da pensare che per come è costruita la logica mvc in questo mini framework sia un pò errata, e tanto vale utilizzarlo.
Proverò allora ad utilizzare subito symfony sperando di capirci e non andare a casaccio.
NO... è impossibile che il programma giri se il codice non è scritto!!
non ti sto prendendo in giro :
Codice PHP:
<?php
/**
* Class View
*
* Provides the methods all views will have
*/
class View
{
/**
* simply includes (=shows) the view. this is done from the controller. In the controller, you usually say
* $this->view->render('help/index'); to show (in this example) the view index.php in the folder help.
* Usually the Class and the method are the same like the view, but sometimes you need to show different views.
* @param string $filename Path of the to-be-rendered view, usually folder/file(.php)
* @param boolean $render_without_header_and_footer Optional: Set this to true if you don't want to include header and footer
*/
public function render($filename, $render_without_header_and_footer = false)
{
// page without header and footer, for whatever reason
if ($render_without_header_and_footer == true) {
require VIEWS_PATH . $filename . '.php';
} else {
require VIEWS_PATH . '_templates/header.php';
require VIEWS_PATH . $filename . '.php';
require VIEWS_PATH . '_templates/footer.php';
}
}
/**
* renders the feedback messages into the view
*/
public function renderFeedbackMessages()
{
// echo out the feedback messages (errors and success messages etc.),
// they are in $_SESSION["feedback_positive"] and $_SESSION["feedback_negative"]
require VIEWS_PATH . '_templates/feedback.php';
// delete these messages (as they are not needed anymore and we want to avoid to show them twice
Session::set('feedback_positive', null);
Session::set('feedback_negative', null);
}
/**

* Useful for handling the navigation's active/non-active link.
