README

A page controller for good and old (and notorious) PHP code.

This is a component created with the hope that it will make things a little easier for people (i.e. me) who have to maintain PHP code written in the old style.

For example, the following

http://example.com/example.php

The goal is to give you the freedom to develop with controllers, even if you access PHP directly.

Installation

PHP 5.6 is targeted. only available in beta alpha version.

composer require "wscore/pages: ^0.1"

Demo

git clone https://github.com/WScore/Pages
cd Pages
composer install
cd public
php -S localhost:8000 index.php

Access localhost:8000 in your browser.

Simple Usage

It's relatively normal.

1. create a Controller for the page and generate an object.
2. Execute the controller with Dispatch.
3. Create an HTML page under the directory for the view.

Create a Controller.

Create it by inheriting from ControllerAbstract.

use WScore\Pages\AbstractController;

class MyController extends AbstractController {
    private $user;
    public function __construct($loginUser) {
        $this->user = $loginUser;
    }
    public function onGet($id) {
        return $this->render('user.php', [
            'user' => $this->user,
        ]);
    }
}

Run the controller.

Execute (Dispatch) the Controller in a PHP file.

use Laminas\Diactoros\ServerRequestFactory;
use WScore\Pages\Dispatch;

$request = ServerRequestFactory::fromGlobals();
$controller = new DemoController();

$view = Dispatch::create($controller, __DIR__ . '/views')
    ->handle($request);
$view->render();

Dispatch is used for session management and CSRF token checking.

The method name of the controller to be executed is determined from one of the following.

• From the HTTP method name.
• From the value of "act" of GET/POST, onMethod is called.

If you access the site normally, onGet will be called. If you post with a form, it is onPost.

View file

In the sample code, "__DIR__ . '/views'" in the sample code is the directory for views.

Create "user.php" in this directory.

use WScore\Pages\View\Data;
/** @var Data $_view */

$user = $_view->get('user');
?>
<! -- show user -->

• $this is the object to return from the controller Dispatch (PaveView).
• $view is an object that holds parameters for drawing (Data).

Other Functions

CSRF tokens.

Outputs a CSRF token from the $view object.

use WScore\Pages\View\Data;
/** @var Data $_view */

echo $_view->makeCsRfToken();

Whenever posted, check for a CSRF token. If the check fails, it will result in a Critical error.

Critical error.

This is a special error for PageView.

use WScore\Pages\PageView;
/** @var PageView $view */

if ($view->isCritical()) {
    $view->setRender('critical.php');
}
$view->render();

• If you catch an exception when executing the controller, it will be a Critical error.

Messages and Flushing

You can specify a message in the controller's message and error.

use WScore\Pages\AbstractController;

class MsgController extends AbstractController
{
    public function onGet()
    {
        $this->message('please try this demo!');
        $this->error('maybe not!');
        return $this->render('message.php');
    }
}

In view PHP, you can display messages, as;

use WScore\Pages\PageView;
/** @var PageView $view */

echo $view->alert();

Flash message

use WScore\Pages\AbstractController;

class MsgController extends AbstractController
{
    public function onGet()
    {
        $this->flashMessage('thank you!');
        $this->flashError('sorry!');
        return $this->location('example.php');
    }
}

With the same PHP code as the message, you can display.
