# Add New Transformer
|
|
|
|
The WordPress ActivityPub plugin offers an advanced built-in transformer, but it also allows other plugins to register new transformers.
|
|
|
|
## Hooks
|
|
|
|
To do that we simply hook to the `activivitypub_transformer_register` action which provides access to the transformer manager as a parameter. Developers can use this manager to add new transformers using the `register()` method of this manager instance.
|
|
|
|
## Registering Widgets
|
|
|
|
To register new transformers use the following code:
|
|
|
|
```php
|
|
function register_new_transformers( $widgets_manager ) {
|
|
|
|
require_once( __DIR__ . '/widgets/widget-1.php' );
|
|
require_once( __DIR__ . '/widgets/widget-2.php' );
|
|
|
|
$widgets_manager->register( new \Transformer_1() );
|
|
$widgets_manager->register( new \Transformer_2() );
|
|
|
|
}
|
|
add_action( 'activivitypub_transformer_register', 'register_new_transformers' );
|
|
```
|
|
|
|
The transformer manager registers new transformers by accepting transformer instances. For more information about the transformer class, read about the [transformer class structure](./transformer-structure/).
