Aturan praktis saya:
halaman apa pun yang mengenai database atau membutuhkan input pengguna dalam bentuk apa pun akan lebih mudah dikelola dengan struktur MVC.
Anda tidak perlu pergi dengan kerangka keseluruhan, jika situs ini cukup sederhana, Anda dapat menggunakan kelas Pengontrol Halaman sederhana untuk setiap halaman yang membutuhkannya ( lihat di atas ). Ini bukan solusi yang dapat diskalakan - jadi ingatlah tujuan jangka panjang proyek ini.
Berikut ini sketsa kasar pengaturan PageController (cepat diretas bersama):
index.php
--------------------------------------------------------
include 'Controller.php';
include 'Db.php';//db connection
include 'View.php';
$Controller = new MyController(new Db(), new View());
$Controller->route($_GET);
$Controller->render();
Controller.php
--------------------------------------------------------
class Controller($db){
/* ensure all collaborators are provided */
public function __construct(Db $db, View $view){
$this->db = $db;
$this->db->connect(array('host','db','user','pass'));
$this->view = $view;
}
/* load the appropriate model data */
public function route($_GET){
//load the right model data and template
switch($_GET){
case $_GET['articles'] === 'cats':
$this->vars = $this->db->get('cats');
$this->template = 'cats.php';
break;
case $_GET['articles'] === 'dogs':
break;
$this->vars = $this->db->get('dogs');
$this->template = 'dogs.php';
default:
$this->vars = array();
}
}
/* render an html string */
public function render(){
echo $this->view->render($this->template,$this->vars);
}
}
View.php
------------------------------------------------------------
class View.php
{
/* return a string of html */
public function render($template,$vars){
// this will work - but you could easily swap out this hack for
// a more fully featured View class
$this->vars = $vars;
ob_start();
include $template;
$html = ob_get_clean();
return $html;
}
}
template cats.php
--------------------------------------------------------
$html = '';
$row_template = '%name%,%breed%,%color%';
foreach($this->vars as $row){
$html .= str_replace(
array(%name%,%breed%,%color%),
array($row['name'],$row['breed'],$row['color']),
$row_template);
}
echo $html;
Db.php
---------------------------------------------------------------
I haven't bothered writing a db class... you could just use PDO
