Hooks

Position custom code

PHP hooks provide a flexible and modular way to extend the functionality of the system. Plugins can easily add custom actions to hooks, allowing developers to customize and extend the system's behavior without modifying its core code, enabling seamless integration and extensibility for plugins within the system. This system incorporates the package available at https://github.com/bainternet/PHP-Hooks.

In the index.php file, you'll find a key hook defined as follows:

$hooks->do_action('start_body_action');

Within a plugin actions/basic.php file, a corresponding function can be declared:

function add_hello_world(){
  echo 'Hello world!';
}

$hooks->add_action('start_body_action','add_hello_world');

In this setup, the 'start_body_action' hook in index.php serves as a designated entry point, and the associated function 'add_hello_world' from the plugin is seamlessly integrated into this hook. When the 'start_body_action' hook is triggered, the specified function is executed.
