Establishment of route mvc

[jonetta]

I understand that the topic that has been afflicted, and there are many (some) examples on the Internet.

The thing is, I have routs, but they're curves. Type:

 array(new Route('/url','className','methodName'));

and mass through new Router;

The point is, for everything to work, I need to create a separate file and write two methods there:

__construct($args=[]) {$this->args = $args} 

and method, to produce a copy of a class called class, parameters and parameters.

Anyway, what's above doesn't matter.

The point is, it's like my experience in writing a rolling, and I''ve got a hard way in my head, alas.

How can you write a system like properly? Not using dop class, that is: Two classes Route, Router:

$router = [new Route('/','main','index')];
new Router($router);

P.s: Don't ask me to write, just push me into thinking. Thank you.

Hello!

MVC means you have controllers to work with a data-produced website and pictures.

In the idea, the structure of the crypt catalogues could be something like:

\Core
    //базовые классы
    Controller.php 
    Model.php
    View.php
    //и роутер
    Route.php
\Controllers
    //тут должны лежать контроллеры, для примера положу блог.пхп для блога
    blog.php
    error404.php
\Models
    //тут должны лежать модели, для примера положу модель блог.пхп для блога
    blog.php
\Views 
    //тут должны лежать вьюхи, для примера положу пару вьюх для блога
    //я тут показал файлы html, но тут могут быть и файлы php
    blog_index.html
    blog_post.html
    error404.html
\More 
    //в этой папке пускай будут лежать какие-нибудь дополнительные классы

The first thing we need to do is describe a carloider so we don't invent bikes and include classes as we wish (to be included in the index file):

autodoader.php*

<?php
spl_autoload_register(function($class){
    $file = SITE_DIR.'/'.str_replace('\\', '/', $class).'.php';
    if (file_exists($file)) require_once $file;
});

Basic classes (they are supposed to have a base function defined):

Core/Controller.php

<?php
namespace Core;
abstract class Controller
{
    public View = null;
public function __construct()
{
    $this-&gt;init();
}

abstract function init();

}

\Core\Model.php

<?php

namespace Core;

abstract class Model

{

}

_

<?php

namespace Core;

class View

{

public function addTemplate($template)

{

//тут нужно описать процедуру подгрузки шаблона

}

public function addView($view)
{
    //тут нужно описать процедуру подгрузки вьюхи
}

public function show()
{
    //тут нужно сделать вывод контента
}

}

In fact, your View class may be a casing over some sort of template to work with him more comfortable. In this case, I highly recommend that you not write your template, but use something ready. I like the best of the ready. Twig♪

It is further necessary to take the URL received and to take the way out of it to call the right controller:

_

<?php

namespace Core;

class Route

{

static public $routes = null;

static function start()
{
    if (self::$routes == null) {
        $url = explode('?', substr(strtolower($_SERVER['REQUEST_URI'], 1)));
        self::$routes = explode('/', $url[0]);
    }
    $controller_name = 'main';
    $action_name = 'index';

    if (!empty(self::$routes[0])) {
        $controller_name = self::$routes[0];
    }

    if (!empty(self::$routes[1])) {
        $action_name = self::$routes[1];
    }

    $controller_class = '\\Controllers\\'.$controller_name;
    $action_name = 'action_'.$action_name;

    $controller = new $controller_class;

    if(method_exists($controller, $action_name)) {
        $controller-&gt;$action_name();
    }
    else {
        Route::Error404();
    }
}

public static function Error404() {
    $protocol = 'http';
    if ($_SERVER['SERVER_PORT']==443) $protocol = 'https';
    $host = $protocol.'://'.$_SERVER['HTTP_HOST'];
    header('HTTP/1.1 404 Not Found');
    header("Status: 404 Not Found");
    header('Location:'.$host.'/error404');
}

}

\Controllers\error404.php

<?php

namespace Controllers;

class error404 extends \Core\Controller

{

public function init()

{

}

public function action_index()
{
    $this-&gt;View-&gt;addTemplate('basic');
    $this-&gt;View-&gt;addView('error404');
    $this-&gt;View-&gt;show();
}

}

\Views\error404.html

<h1>Ошибка 404</h1>

<p>Страница не доступна или не существует.</p>

And you have to have something. index.php (or some other file) that will start everything.

<?php

include "autoloader.php";

\Core\Route()::start();

Come on! Even though I've been in some detail, I just wanted to push you into some kind of automation. Rooting can also be performed with files (writing paths to some Rooting file/fail, for example Symfony). Anyway, I wrote the code right here without checking his work capacity. I also don't insist on his ideals.

I'd be glad if I could help.
