README

Parable is a PHP framework with two goals: it's just enough, and it doesn't enforce a way to build.

Install

Php 8.0+ and composer are required.

$ composer require parable-php/parable

And to set up parable, run the following and follow the interactive questions:

$ vendor/bin/parable install

Usage

After installation (and you chose to install the example app) you'll have an example application to look at.

Parable 2.0 is based around plugins to arrange everything. It's not a framework that makes you do things a certain way outside of this.

If you want to set up routes? RoutesPlugin. Set up the configuration? ConfigPlugin. As long as you add these to Boot.php they'll be loaded at the appropriate time.

Application::PLUGIN_BEFORE_BOOT should contain plugins that need to be loaded before the database or sessions are loaded. ConfigPlugin, for example, should be here so you can set up the database. Application::PLUGIN_AFTER_BOOT is for plugins that require a database, for example.

Example `ConfigPlugin`

Anything within the config namespace parable is used by the Application class to set up specific things. You don't have to use these (this example file shows all possible values) but you can if it's faster/easier.

In the example below, yourstuff is just an example of adding your own config values to the Config instance used throughout the application. Feel free to add whatever you want here!

class ConfigPlugin implements PluginInterface
{
    public function __construct(
        protected Config $config
    ) {}

    public function run(): void
    {
        $this->config->setMany([
            'parable' => [
                'default-timezone' => 'Europe/Amsterdam',
                'database' => [
                    'type' => Database::TYPE_MYSQL,
                    'host' => 'localhost',
                    'username' => 'username',
                    'password' => 'password',
                    'database' => 'database',
                    'charSet' => 'utf8mb4',
                    'port' => 40673,
                    // all other values, see https://github.com/parable-php/orm/blob/master/README.md for more
                ],
                'session' => [
                    'enabled' => true,
                    'name' => 'app_session_name',
                ],
                'debug' => [
                    'enabled' => (bool)getenv('DEBUG_ENABLED'),
                    'levels' => E_ALL | ~E_DEPRECATED,
                ],
            ],
            'yourstuff' => [
                'extensions' => [
                    CleanerExtension::class,
                ],
            ],
        ]);
    }
}

Example `RoutingPlugin`

To set up routing, just add a RoutingPlugin and place it either in PLUGIN_BEFORE_BOOT or PLUGIN_AFTER_BOOT depending on whether you need the session/database to be active first.

For full information on parable-php/routing, read the README.md of that package.

class RoutingPlugin implements PluginInterface
{
    public function __construct(
        protected Router $router,
        protected Path $path
    ) {}

    public function run(): void
    {
        $this->router->add(
            ['GET'],
            'site-index',
            '/',
            [SiteController::class, 'indexAction'],
            ['template' => $this->path->getPath('src/Templates/Site/index.phtml')]
        );
    }
}

Being able to set template is something specific to Parable 2.0.0, parable-php/routing by default doesn't understand templates, so it's being passed as metadata, and the framework itself can deal with the template metadata.

The template files are expected to just be php files (but named phtml here to indicate it's a template). See welcome.phtml in the example app to see how to use it.

By setting this at the top of the file, you get access to a lot of built-in features:

/** @var \Parable\Framework\Http\Template $this */

See the top-most doc-block of Template.php to see what's available, but you can do anything from accessing the Di Container ($this->container) to events ($this-events).

A question I've gotten regularly is 'how do I pass data from a controller to a template/view?'.

Well, my dear friend, it's easy. In the controller:

public function __construct(protected DataCollection $dataCollection) {}

public function someAction() {
    $this->dataCollection->set('viewData', [
        'value' => 'this is value',
        'bool' => true,    
    ]);
}

And in the template, if you've added @var \Parable\Framework\Http\Template $this like I suggested you do? Easy!

echo 'Value is ' . $this->data->get('viewData.value');

The DataCollection from parable-php/getset is specifically intended for free-form data storing and sharing across files, so it's perfect for this.

Note that you don't need either controllers OR templates! You can also just pass an anonymous function in, which can be perfect for small and simple REST APIs:

$this->router->add(
    ['GET'],
    'api-index',
    '/api',
    static function () {
        echo json_encode([
            'status' => 'success',
        ]);
    },
);

Packages used in `parable-php/framework`

Check the below packages for any questions you might have about how to approach them. Their behavior is fully available to you as part of the framework and Parable 2.0 doesn't do anything special to stop you or wrap it in weird ways. Mostly what's been added only serves to do setup as part of the Config flow, none of which is required.

Thank youses

I want to thank the following people for inspiring, challenging and brainstorming with me about ideas and how to make Parable the best framework I never found anywhere else:

Dave van der Brugge for his almost insane eye for detail and asking 'why?' so often it made me cry once.
Thijs Riezebeek for being my braining sparring partner whether he wants to or not. Will never ever ever not challenge me on every single decision ever. Which is good!
Jerry van Kooten for always going well beyond the knowledge I'd expect him to have and testing my stuff out. Also for actually creating PRs when he hated something, improving a few packages massively.
Lucas Grossi for choosing to go with Parable's alpha version for an actual professional project, forcing me to release 2.0.0 because otherwise it'd never be approved.
