A small class implemeting the factory method using WordPress' filter system, designed for making WordPress classes extensible.
composer require perry-rylance/wordpress-class-factory
Let's imagine we have a use case where plugin B would like to extend one of plugin A's classes, allowing plugin A to instantiate plugin B's class without any knowledge of it.
namespace ExamplePlugin;
use PerryRylance\WordPress\Factory;
class Vehicle extends Factory
{
public function name(): string
{
return "A generic vehicle";
}
}
add_action('init', function() {
$vehicle = Vehicle::createInstance();
echo $vehicle->name();
exit;
});
class Camper extends Vehicle
{
public function name(): string
{
return "A wonderful camper";
}
}
Vehicle::override(fn() => return new Camper());
The above will output "A wonderful camper".
