What is the Core Plugin?

The Flynt Core WordPress plugin is the main building block of the Flynt Framework. It provides a small public interface, combined with several WordPress hooks, to achieve the main principles of the framework.

This plugin essentially functions as a HTML generator with two key steps:

  1. Given a minimal configuration, the Flynt Core plugin creates a hierarchical plan for how the site will be constructed (the Construction Plan).
  2. The Construction Plan is parsed and rendered into HTML.

Each configuration passed to the plugin represents a single component. This configuration can also contain additional, nested component configurations, which are contained within areas.


To install via composer, run:

composer require flyntwp/flynt-core

Activate the plugin in the WordPress back end and you’re good to go.


Hello World

To see the simplest way of using Flynt Core, add the following code to your theme’s functions.php:

$componentManager = Flynt\ComponentManager::getInstance();

add_filter('Flynt/renderComponent?name=HelloWorld', function () {
    return 'Hello, world!';

This defines a new component (‘HelloWorld’), which when rendered, will output the text ‘Hello, world!’.

To render the component, add the following code to your theme’s index.php:

    'name' => 'HelloWorld'

Initialize Default Settings

We recommend initializing the plugin’s default settings. Do this by adding the following line of code to your theme’s functions.php:


This will:

  • Implement the component structure.
  • Load component scripts.
  • Enable PHP file rendering.

This also adds the following hooks:

// Set the config path to './config'.
add_filter('Flynt/configPath', ['Flynt\Defaults', 'setConfigPath'], 999, 2);

// Parse `.json` config files.
add_filter('Flynt/configFileLoader', ['Flynt\Defaults', 'loadConfigFile'], 999, 3);

// Set the component path to `./Components`.
add_filter('Flynt/componentPath', ['Flynt\Defaults', 'setComponentPath'], 999, 2);

// Load ./Components/{$componentName}/functions.php from every registered component.
add_action('Flynt/registerComponent', ['Flynt\Defaults', 'loadFunctionsFile']);

// Render `./Components/{$componentName}/index.php` and make view helper functions `$data` and `$area` available (see explanation below).
add_filter('Flynt/renderComponent', ['Flynt\Defaults', 'renderComponent'], 999, 4);

With the Flynt/renderComponent filter added above you can now use the following helper functions in your template files:

  • $data is used to access the component’s data in the view template.
  • $area is used to include the HTML of an area’s components into the components template itself.
