Welcome to the PussyCat FrameWork ᓚᘏᗢ

a framework for WebDevelop based on the mvc structure. The name of this project for Fun because everyone can use it. Completely simple and powerful structure for all your projects

Starting an application using this framework

1. First, download the framework, either directly or by cloning the repo.
2. Run composer update to install the project dependencies.
3. Configure your web server to have the public folder as the web root.
4. Open App/Config.php and enter your database configuration data.
5. Create routes, add controllers, views and models.

See below for more details.

Configuration

Configuration settings are stored in the App/Config.php class. Default settings include database connection data and a setting to show or hide error detail. You can access the settings in your code like this: Config::DB_HOST. You can add your own configuration settings in here.

Routing

The Router translates URLs into controllers and actions. Routes are added in the front controller. A sample home route is included that routes to the index action in the Home controller.

Routes are added with the add method. You can add fixed URL routes, and specify the controller and action, like this:

$router->add('', ['controller' => 'Home', 'action' => 'index']);
$router->add('posts/index', ['controller' => 'Posts', 'action' => 'index']);

Or you can add route variables, like this:

$router->add('{controller}/{action}');

In addition to the controller and action, you can specify any parameter you like within curly braces, and also specify a custom regular expression for that parameter:

$router->add('{controller}/{id:\d+}/{action}');

You can also specify a namespace for the controller:

$router->add('admin/{controller}/{action}', ['namespace' => 'Admin']);

Controllers

Controllers respond to user actions (clicking on a link, submitting a form etc.). Controllers are classes that extend the Core\Controller class.

Controllers are stored in the App/Controllers folder. A sample Home controller included. Controller classes need to be in the App/Controllers namespace. You can add subdirectories to organise your controllers, so when adding a route for these controllers you need to specify the namespace (see the routing section above).

Controller classes contain methods that are the actions. To create an action, add the Action suffix to the method name. The sample controller in App/Controllers/Home.php has a sample index action.

You can access route parameters (for example the id parameter shown in the route examples above) in actions via the $this->route_params property.

Action filters

Controllers can have before and after filter methods. These are methods that are called before and after every action method call in a controller. Useful for authentication for example, making sure that a user is logged in before letting them execute an action. Optionally add a before filter to a controller like this:

/**
 * Before filter. Return false to stop the action from executing.
 *
 * @return void
 */
protected function before()
{
}

To stop the originally called action from executing, return false from the before filter method. An after filter is added like this:

/**
 * After filter.
 *
 * @return void
 */
protected function after()
{
}

Views

Views are used to display information (normally HTML). View files go in the App/Views folder. Views can be in one of two formats: standard PHP, but with just enough PHP to show the data. No database access or anything like that should occur in a view file. You can render a standard PHP view in a controller, optionally passing in variables, like this:

View::render('Home/index.php', [
    'name'    => 'Dave',
    'colours' => ['red', 'green', 'blue']
]);

The second format uses the Twig templating engine. Using Twig allows you to have simpler, safer templates that can take advantage of things like template inheritance. You can render a Twig template like this:

View::renderTemplate('Home/index.html', [
    'name'    => 'Dave',
    'colours' => ['red', 'green', 'blue']
]);

A sample Twig template is included in App/Views/Home/index.html that inherits from the base template in App/Views/base.html.

Import Files

in config file set app_url in public folder for example assets,storage folder { { dir } } in view linked to app_url

link css file

<link rel="stylesheet" href="{ { dir } }assets/css/main.css">

link js file

<script src="{ { dir } }assets/js/mai.js"></script>

Models

Models are used to get and store data in your application. They know nothing about how this data is to be presented in the views. Models extend the Core\Model class and use PDO to access the database. They’re stored in the App/Models folder. A sample user model class is included in App/Models/User.php. You can get the PDO database connection instance like this:

$db = static::getDB();

Use Models in Controllers

Step 1 - use

use App\Models\User;

User Name of Models

Step 2 - use

$Users = User::getAll();

Errors

If the SHOW_ERRORS configuration setting is set to true, full error detail will be shown in the browser if an error or exception occurs. If it’s set to false, a generic message will be shown using the App/Views/404.html or App/Views/500.html views, depending on the error.

Web server configuration

Pretty URLs are enabled using web server rewrite rules. An .htaccess file is included in the public folder. Equivalent nginx configuration is in the nginx-configuration.txt file.
